Mimbus Discover - User Guide

When the application is launched, the user is in a main room called the "lobby" where a screen displaying the main menu of the simulator is located in front of him.

The main menu allows the user to authenticate themselves and to select an exercise to perform. At the end of each exercise, the user will be teleported back to the lobby.

The main menu is organised as follows:

Initially, it is necessary to choose the class in which the user who wants to launch an exercise is located.

This menu is only displayed when the simulator is connected to the online platform Vulcan.

Once the class has been selected, the user must be authenticated. Clicking on the user’s name will bring up a window in which the user’s PIN code, a four-digit number set in Vulcan, must be entered. Users who are not assigned to a Discover learning path will appear in grey. It will not be possible to select them on the simulator.

In offline mode, a demo user will be automatically selected.

Once the user is authenticated, the module selection menu is displayed.

The available modules are "Building", "Industry", "Services" and "Tutorial". Pointing at a module allows see the description of the module, while clicking on a module will select it.

The tutorial allows you to familiarise yourself with the commands by running through a set of simple scenarios.

On this page, the exercises within the previously selected module are displayed. Pointing at an exercise displays a description of the selected exercise, while clicking on an exercise will launch it.

Objective: to learn how to move around the virtual world and recognize markers that indicate a specific location.

The user will learn to move by teleportation. To leave this first room, the user will be asked to teleport to the next room.

By pressing the "Teleportation" button, it is possible to initiate a teleportation. As long as the button is held down, you can choose the teleportation destination. When you release the button, the teleportation will be performed.

A parabolic pointer coming out of the controller will then be visible, symbolizing the path taken during a teleportation. If teleportation is possible, this pointer is violet; if not, it is red.

Objective: To learn to pick up an object, release it and place it on a magnetized area, and to recognize the associated visual feedback.

The user will be invited to bring their hand close to an object, visualize the associated visual feedback (blue outline), then pick up the object using the associated button and drop it onto a designated area on a second display.

Once this action is completed, the user will be prompted to exit the room by opening a door, giving them the opportunity to use the "Grab an item" interaction again on the handle.

Objective: To learn how to interact with tools or buttons, and recognize the associated visual feedback.

The user will be asked to interact with an object on a display (the object will be surrounded by a yellow outline indicating the possibility of activating it) and activate it using the associated button.

To exit the tutorial, the user will have to move to the back of the room and press the elevator button using the "Interact" button. A fade to black will return the user to the lobby.

To complete the exercise, the user must carry out the actions in the following order:

The user starts the scenario with the following briefing:

To get to your workstation you will have to use the scaffolding and go to the 4th floor.

To use the ladder, the user uses the "Grab an object" button to climb and the "Interact" button to open the hatch.

At his workstation, tools will be provided: a small and a large wooden board as well as a nail gun.

The user grabs and places the smallest board at the left end of the façade. They will have to take the nail gun in order to place the nails in the intended places using the "Interact" button. The user will not be able to proceed to the next step if a sufficient number of nails have not been placed. The user will then be able to place the second board, and perform the same operation.

Once the steps have been completed, the user will be teleported to the lobby in front of the scoring screen.

To complete the whole exercise, the user will have to carry out the actions in the following order:

The user starts the scenario with the following briefing:

Once the briefing is complete, the user is teleported to a corridor with two sockets (one functional, the other not) and two wall lights, one of which is defective. At the end of the corridor, a circuit breaker will be visible at the beginning of the scenario.

Their first task is to identify and replace the faulty socket. To do this, they grab the socket tester on the cart and check both wall sockets (by inserting the tester into the socket). The tester displays 230V if the tested socket is functional. If not, the tester displays OV.

Once the faulty socket has been identified, the user grabs the insulating gloves and helmet. To ensure safety, the user should turn off the circuit breaker ("Socket 1 corridor" or "General") before working on the socket.

They then go to the defective socket and detach it. In order to completely remove the plug, the user must loosen the screws on the 3 cables with the insulated screwdriver. The user can then pick up the defective plug and replace it with a new one.

The user then retightens the cable screws and installs the socket in the wall. Finally, the user switches the power back on to the sockets from the electrical panel and tests the replaced socket once again.

Their second task is to replace the bulb of the defective wall light. To avoid any risk of electrocution, the user must turn off the circuit breaker of the sconces from the electrical panel (they can turn off the "General" circuit breaker if they wish).

The user picks up the screwdriver and loosens the 3 screws of the defective light fixture’s cover. Once the cover is removed, they grab the bulb and replace it with a new one. The user can then replace the cover and screw it back on.

Before finishing, the user turns the power back on and checks that the light is working properly.

Once the steps have been completed, the user will be teleported to the lobby in front of the scoring screen.

To complete the whole exercise, the user will have to carry out the actions in the following order:

The user starts the scenario with the following briefing:

In order to carry out the task, the user will have the necessary materials available on the workbench to their right at the start of the exercise.

The user grabs a rail, and comes to place it on the "ghost" of its final position. It will not be necessary to screw the rails down. The user will have to do the operation once to treat the whole length of the façade.

Once the rails have been laid, the user will need to grab an insulation panel from the workbench. The drop zone is highlighted on the front; the user drops the panel onto the zone.

The user takes the drill on the workbench, and drills 5 holes in the panel at the designated locations by pressing the "Interact" button near the areas.

The user grabs the roll of reinforcing fabric, and applies it to a first area at the bottom of the façade by pressing the "Interact" button. A strip appears on the whole height of the building. The user repeats the operation twice.

The user uses the scaffolding ladder to access the first floor.

They grab the spray nozzle to spray plaster over the entire area required by sweeping the area while holding the "Interact" key.

Once the area has been treated, they must confirm their action by clicking on the "I’m done" button on the instruction panel.

The user then uses the ladder to access the 2nd floor. They grab the scraper and applies it to the entire area required.

Once the area has been treated, the user must confirm his action by clicking on the "I’m done" button on the instruction panel.

Once the steps have been completed, the user will be teleported to the lobby in front of the scoring screen.

To complete the whole exercise, the user must carry out the actions in the following order:

The user starts the scenario with the following briefing:

Once the briefing has been accepted, the user is teleported to a bathroom being renovated. In this room there is a workbench with the tools needed for the job, a sink, a cabinet and an assembly plan.

The user’s first task is to install the cabinet unit.

With the help of the assembly plan on the wall, the user must determine the position of the cabinet and drill two of the eight holes on the wall using a drill.

Once the holes have been drilled, the user selects the correct anchor for the wall and places the anchor in the holes.

The cabinet can then be placed on its location.

Using the cordless screwdriver, fasten the furniture to the wall.

With the cabinet installed, pick up the sink and place it on top of the cabinet.

The faucet and its hoses are already mounted on the basin.

The user will need to grasp the end of the hot and cold water hoses and connect them to the correct water supply.

The next step is to connect the sink’s drain pipes.

As the wall-mounted drain is 50mm diameter, the user should place the Ø50-Ø40 reducer in the elbow to reduce the diameter to 40mm.

They then take the L150 Ø40 pipe and inserts it on the reducer.

They then place the Ø40 elbow at the end of the previously laid pipe.

Finally, they place the L350 Ø40 pipe between the last pipe laid and the sink’s drain.

In order to complete the exercise, the user will have to test their assembly by operating the faucet.

Once the steps have been completed, the user will be teleported to the lobby in front of the scoring screen.

The user starts the scenario with the following briefing:

Once the briefing has been accepted, the user can move freely around the entire site.

Hazards are scattered throughout the site and a fatal error occurs if the user gets too close to a hazard. The user will complete the exercise when they have identified 10 hazards.

In this mode, the user does not have the option of securing the hazards they encounter, and can exit the exercise at any time by clicking on the cross on the watch on their left wrist.

To complete the exercise, the users will have to proceed with the actions in the following order:

The scenario is divided into 3 parts.

To complete the exercise successfully, the user must perform the following actions:

The scenario begins on an active construction site. In front of the user is a control screen used to start and complete the exercise.

All the tools needed to perform the exercise are placed on the sawhorse in front of the user.

The concrete blocks are stacked on the pallet to the left. There are four types:

After reviewing the environment and the briefing, the user must complete the unfinished wall to their right.

Click the Start button to begin the task.

First, apply the mortar using the applicator roller. To do this, pick up the roller and apply mortar along the top edge of the wall.

Be sure to cover the entire area with mortar before proceeding to the next step.

When all the mortar has been applied, take a half block with an opening and place it beside the doorway.
It will initially not be level; use the mallet and the level to check and adjust its alignment.

Repeat this process with a standard block on the opposite side of the course.

Place the mason’s line over one of the two blocks positioned earlier.

Continue placing the remaining blocks to complete the wall.

When the wall is complete, the user must click the Finish button in the interface.

To validate the whole exercise, they must carry out the actions in the following order:

The user starts the scenario with the following briefing:

The scenario will start in a hangar with a complete production line switched off. The nearby screen will show the maintenance operations and the time remaining before production starts. It is also on this screen that the user can use to end the exercise.

The necessary tools (rag and pressurized grease can) will be placed on a table in the user’s field of vision.

The user will have to consult the screen in order to learn about their tasks.

Their first task is to identify and clean the 20 sensors hidden throughout the production line.

The user will need to grab the cloth on the nearby table, locate and clean the sensors on the line.

Once the 20 sensors have been cleaned, his second task will be to grease some of the components of the production line.

The user will have to grab the degreasing spray and use it with the "Interact" button on the three elements in the picture.

Once the parts have been greased, the user should return to the screen and click on the "Resume Production" button, which will end the countdown and the exercise. The user is then teleported back to the lobby to the scoring screen.

To complete the whole exercise, the user must carry out the actions in the following order:

The user starts the scenario with the following briefing:

Refrigerant

After changing a solenoid valve, you will have to perform a leakage test.

At the start of the scenario, the user is presented with a refrigerant circuit and the tools needed to carry out the task: a nitrogen cylinder, pressure gauges, a leak detection spray and a vacuum pump.

The first step of the exercise will be to fill the nitrogen circuit using the pressure gauges.

First, the user connects the yellow hose from the pressure gauges to the regulator on the nitrogen cylinder and opens the valve on the hose.

To put the nitrogen into the system, the user will need to open the nitrogen cylinder and adjust the pressure.

The pressure regulator on the cylinder will then show 100 bar at the inlet and 20 bar at the outlet. Note also that the pressure gauges will read 20 bar.

The circuit is then filled, so the user proceeds to the leak test on the previously replaced part.

Using the spray, the user sprays the liquid on the connections of the part (these connections will be highlighted) to identify the presence of a leak. The user will then have to report his findings on the instruction panel by answering "No" to the question asked.

At the end of the leakage test, their mission is to empty the nitrogen from the circuit.

To do this, they will have to stop the gas circulation by closing the nitrogen bottle and the yellow hose of the pressure gauges, disconnect the yellow hose and open the valve of the hose to release the nitrogen. The pressure gauges will then indicate 0 bar of pressure.

Finally, they use the vacuum pump to completely drain the nitrogen from the system.

They should then connect the yellow hose to the vacuum pump, turn on the vacuum pump.

When the pressure indicated on the manometers is lower than -0.63 bar, they should close the valve of the yellow hose and turn off the vacuum pump.

Once the mission is completed, the user will be teleported to the lobby in front of the scoring screen.

To complete the exercise, they must perform the actions in the following order:

The user starts the scenario with the following briefing:

The user stands in front of the chicken and proceeds to cut the neck of the chicken.

With their blade, they must follow the cutting line marked with small dots.

Once the neck is cut, the user will need to grab the part. A red arc will appear indicating that the part should be placed in the red bin.

The user can move on to the next piece: the wing.

They cut and place the first wing on the cutting board and then the second. Each wing needs to be recut in 3 parts. They can then proceed to the sorting procedure on each part of the cut wing.

The user then proceeds to cut and sort the first leg. This operation must be repeated for the second leg as well.

Once the legs have been sorted, the user cuts and sorts the first fillet. This operation must be repeated for the second fillet as well.

Finally, the user cuts and sorts the upper cartilage.

When the user believes that they have finished their cutting work, they press the validation button which will end the countdown. The user will then be teleported back to the lobby in front of the scoring screen.

To complete the whole exercise, the user will have to follow the following instructions:

The exercise is divided into two parts: one consists of weighing powder on a scale. The other part consists in mixing and heating different products in a triple-neck flask in order to merge them with the help of a reflux heater with a magnetic stirrer.

To begin, the user will approach the scales, and turn on the single scale.

Then, they will place an empty and clean jar on the scale and perform the tare. Then, they will retrieve the jar and place it on the work surface.

The user must transfer 180 mg of 4-hydrazino benzenesulfonic acid into the jar he has just tared. When opening the bottle, the user must be careful to place the cap the right way up on the work surface.

They must use the spatulas to perform this decanting.

The user must not put the product back into its original container. If they have taken too much product, they must put the powder in the waste beaker

The user should transfer product into the jar outside the scale, otherwise they may drop powder on the scale pan, which will distort the weight. At this point, they must take the brush to clean it.

When the user is sure of the quantity of product weighed, they will confirm by pressing the 3rd button.

The second part of the exercise begins. They will have to approach the fume hood and open it halfway.

Next, place the funnel on the left side of the triple-neck flask.

They must transfer all the powders (including the one that has just been weighed) into the triple-neck flask with the help of spatulas, above the funnel: 180 mg of 4-hydrazino benzene sulfonic acid and 218 mg of 2,2,3,3-tetrahydroxysuccinic acid*.

Then, they should transfer 0.56 ml of H2SO4 into the triple-neck flask (still above the funnel), and then close the bottle of H2SO4.

When the triple-neck flask is filled, the user can remove the funnel and replace it with the triple-neck flask cap.

The user must interact with the lab elevator to adjust the height of the stirrer until the heat-on touches the triple-neck flask.

The user will continue with the set-up: the reflux column should be positioned on the center hole of the triple-neck flask and the thermometer on the right hole of the triple-neck flask.

The user will set up the reaction, setting the control temperature on the blue probe to 65 °C by clicking on the arrows. The longer they presses, the faster the temperature changes.

On the magnetic stirrer, it is necessary to set the speed of rotation between 350 and 500 rpm and the heating temperature to 60 °C. To do this, they must press the interaction button near the wheels and rotate his wrist to change the values.

The user can observe misting on the walls of the triple-neck flask and see that the solution has changed color if they have followed the instructions correctly.

To complete the exercise, the user must check the temperature of the solution by clicking on the icon near the thermometer. The user will then be teleported back to the lobby in front of the scoring screen.

To complete the exercise, the user must carry out the actions in the following order:

Warehouse floor plan

The scenario is divided into 2 parts.

At the start of the exercise, three hazards are randomly generated in the warehouse. The user can use the laser pointer attached to his belt at the start of the exercise to point them out, although missing them has no impact on the overall score.

The list of hazards that can be found is as follows:

To successfully complete the exercise, the user must perform the following steps in the correct order:

The user starts the scenario with the following briefing:

The user positions themselves in front of the workbench and examines the cutting plan. Using a pencil, they draw thr first line.

Following the first line, the user must place the board in front of the band saw and hold the board with both hands to proceed with the cut along the line.

They can then use the pusher when their hand nears the warning zone.

Once the first cut is made, the user must recycle the scrap by placing it in the bin located to the left of the band saw. They place the remaining section of board on the workbench in order to draw the second cutting line using the pencil.

Once the second cut is made, the user must recycle the scrap by placing it in the bin located to the left of the band saw. They place the finished board on the workbench.

Once the steps are completed, the user will be teleported to the lobby in front of the scoring screen.

To complete the whole exercise, the user will have to perform the actions in the following order:

The user starts the scenario with the following briefing:

At the start the user is in a corridor where they are asked to clean the task with the brush.

The user grabs the handle of the machine left near the area and cleans the floor.

Once the action is complete, they will have to go to the classroom. To get there, they will have to interact with the door handle.

Two tasks are visible in the classroom. All the necessary products and buckets will be provided as well as all the maintenance materials.

The user is first asked to treat the stain on the platform with the microfiber mop.

The user should consult the pictograms on the cleaning products to check the compatibility of each with the surface to be treated. As the platform is made of wood, the user must choose the water canister, the only product compatible with the floor.

While holding the canister, the user pours the contents of the water canister into the bucket.

The user then grabs the microfiber mop (in blue) and wets it by dipping it into the bucket.

The user will then be able to clean the stain by sweeping the area while gripping the broom handle.

Once the stain on the stage has been cleaned, the user will be asked to clean the blue ink stain.

The user repeats the previous operations, but this time choosing the soap cleaner as the cleaning product compatible with the linoleum floor and the mop (in green).

Once the mission is completed, the user is teleported back to the lobby in front of the scoring screen.

To complete the whole exercise, the user will have to perform the actions in the following order:

The user starts the scenario with the following briefing:

When starting, the user is presented with a car mounted on a hydraulic lift in a garage environment. Their first task is to change the oil in this car.

To do this, the user raises the hydraulic lift using the control panel in order to access the drain plug located under the car’s engine.

Before loosening the plug, they grabs the drain pan and place it on the ground under the plug. They take the wrench on the trolley and loosen the plug by placing the wrench over the drain plug and pressing the trigger.

If the user has placed the drain pan correctly, the used oil will pour into the pan.

The user must then dispose of the oil in the waste oil container (blue).

The user closes the drain plug and positions the hydraulic lift on the ground in order to open the front hood of the car.

Under the hood is the engine oil tank. Using the oil can on the trolley, the user removes the cap and pours the contents of the can into the tank.

Finally, they put the cap back on and closes the hood.

The user’s second task is to replace the car’s worn-out tire.

In this scenario, the user will only work on the right front wheel (passenger side).

First, thee position the lift so that they can access the wheels.

They take the impact driver from the tool stand and loosen the 5 bolts on the right front wheel.

Once the bolts are loosened, they pick up the wheel and place it on the tire changer tray behind them. They operate the tire changer to remove the tire.

They should then pick up and place the used tire in the used tire recycling area.

They pick up one of the tires (carefully selected) from the tire rack and place it on the rim of the previously removed wheel.

Now that the wheel mounting is complete, the user can proceed to the wheel balancing step. The user picks up the wheel, places it on the balancing machine and activates it.

To ensure that the weight of the wheel is distributed evenly, the balancing machine must indicate 0 - 0. If the result of the balancing machine is not correct, the user must install counterweights.

For example: the balancer indicates 0 - 10 as a value (the leftmost number corresponds to the left side of the wheel and the rightmost number to the right side of the wheel).

The user should therefore place a 10 on the right side of the wheel. The user will then operate the balancer again until the values show 0 - 0.

The wheel is finally balanced, the user can then grab the wheel and place it on the car in its intended location. Finally, they take the impact screwdriver again and reattaches the 5 bolts.

Once the steps have been completed, the user will be teleported to the lobby in front of the scoring screen.

The user can complete the tasks in any order they wish, but it is best to follow the order below in order to meet the ideal schedule.

Here is an example of a timeline of actions that would complete the whole exercise.

The user starts the scenario with the following briefing:

Once the briefing is accepted, the user starts in the entrance of the house. The elderly person’s avatar is on the sofa in the living room. A to-do list is prominently displayed on the kitchen counter.

On arrival, the user can go and greet Rose, who will inform the user that she has broken a glass and ask her to pick up the debris.

The user then goes to the kitchen, grabs the broom, and sweeps up the debris.

They consult the schedule to find out what their tasks are.

If Rose has to eat before 12:30, it is best for the user to prepare the meal first.

To do this, they opens the bottom compartment of the fridge and grab the pot of soup.

They put the pot on the cooker and heat the soup.

Once the soup is warm (steam comes out of the pot indicating it is ready), they pick up the pot and the plate on the island and bring them to the dining room table.

The user will need to speak to Rose to indicate that the meal is ready.

During the meal, the user can then chat with her.

Once the conversation is over, the user should consult with Rose to help her back to the sofa.

The user can then pick up the mail. They pick up the newspaper at the bottom of the front door and put it on the kitchen island.

They talk to Rose again and ask her if she needs anything. Rose then asks them to bring her the book.

They grab the book from the coffee table in front of her and give it to her.

Finally they have to go to the bedroom and make the bed.

It is now 4pm, the user has finished their day. They should inform Rose that he is leaving.

Once the steps are completed, the user will be teleported back to the lobby in front of the scoring screen.

To complete the exercise successfully, the user must perform the following actions in order:

To validate the exercise, the user must perform the actions in the following order:
