1. Introduction

This document lists the various features available in the MIMBUS LOGISTICS simulator.

First, features that are not specific to a particular exercise will be listed.

Next, we will detail each instruction associated with a exericse in the simulator, i.e., how to complete the task assigned by the system in order to move on to the next step during the simulation.

2. General operation

2.1. Controllers

The application is compatible with all OpenXR complient headsets. Depending on the virtual reality headset used, the controllers and hence the associated keys are different.

2.2. Authentication

md lobby
Figure 1. Main screen in the lobby

When the application is launched, the user finds themselves in a main room called the “welcome hall,” where they see a screen displaying the simulator’s main menu.

The main menu allows the user to log in and select the exercise they wish to perform. At the end of each exercise, they will be teleported back to this screen.

md screen breakdown
Figure 2. Main screen in the lobby

The main menu is organized as follows:

  1. Class selection (online mode only): classes are configured on the VULCAN online platform.. Visual indicator of progress on the authentication and exercise selection pages:

    1. Authentication

    2. Module selection

    3. Level selection

    4. Exercise selection

  2. Switching to offline mode: exercises are no longer retrieved from Vulcan and results will not be sent back to Vulcan. A generic user named DEMO is then used instead of a student connected to Vulcan.

  3. Displaying the settings screen: the settings screen allows you to change the simulator language, among other things..

  4. Quitting the application

2.2.2. Class Selection

First, the user needs to select the class in which they are enrolled.

This menu only appears when the simulator is connected to the VULCAN online platform.

Click once to select the class, then click again to confirm your selection.

The score screen is organized as follows:

  1. Validation or rejection of the exercise with results displayed as a percentage.

  2. Exercise evaluation criteria. The evaluation criteria are specific to each exercise.

  3. Events shows all actions validated by the user based on the time elapsed since the start of the exercise.

  4. [Optional] Movements shows a map of the user’s movements during the exercise

2.6. Didacticiel

Afin de se familiariser avec les interactions disponibles, un scénario didacticiel peut être lancé depuis le menu de choix du module.

Le didacticiel aura pour but d’apprendre à l’utilisateur les commandes de son matériel de réalité virtuelle et les différentes métaphores utilisées dans l’application de façon claire et progressive. Il prendra place dans un environnement neutre et dépouillé afin de ne pas distraire l’utilisateur des différentes actions attendues.

Un panneau permettant de connaitre l’association entre les touches de la manette de l’utilisateur et les actions sera toujours visible pendant l’expérience.

md controllersPoster
Figure 9. Panneau présentant les différents boutons de contrôle des manettes

Le didacticiel se présente sous la forme de salles à thèmes successives, que l’utilisateur devra valider les uns après les autres :

  • Se déplacer

  • Saisir et déplacer un objet

  • Interagir avec un objet

Dans chacune des salles, l’utilisateur apprendra une action (utilisation d’un bouton) dans un espace dédié, puis devra mettre en pratique cette action pour quitter la salle et passer à la suivante. Une fois les trois salles validées, l’utilisateur passera une dernière porte pour terminer le didacticiel.

md didacticiel graph

2.6.1. Déplacement

Objectif : apprendre à se mouvoir dans le monde virtuel et à reconnaitre les marqueurs indiquants de se positionner à un emplacement précis.

L’utilisateur apprendra à se déplacer par téléportation. Pour quitter ce premier atelier, l’utilisateur sera invité à se téléporter à nouveau vers la salle suivante.

En appuyant sur la touche "Téléportation" (cf. chapitre Contrôleurs), il est possible d’enclencher une téléportation. Tant que le bouton est maintenu, vous pouvez choisir où vous téléporter. Au relâchement du bouton, la téléportation sera effectuée.

Un pointeur parabolique sortant du contrôleur sera alors visible et symbolise le chemin parcouru lors d’une téléportation. Si une téléportation est possible, ce pointeur est de couleur violette; dans le cas contraire, celui-ci est de couleur rouge.

2.6.2. Saisir / déplacer un objet

Objectif : Apprendre à saisir un objet, le lâcher et le déposer sur une zone aimantée. Reconnaître le retour visuel associé.

L’utilisateur sera invité à approcher sa main d’un objet, visualiser le retour visuel associé (contour bleu), puis à saisir cet objet à l’aide du bouton associé pour et le déposer sur une zone prévue à cet effet sur un second présentoir.

Cette action validée, l’utilisateur sera invité à sortir de la pièce en ouvrant une porte, ce qui lui donnera l’occasion d’utiliser à nouveau l’interaction "Saisir un objet" sur la poignée.

4.4. Using the picking scanner

Each user will be equipped with a picking scanner.

This scanner has a screen that displays the locations where the products to be picked are located.

Note

The locations indicated on the scanner may not be correct if another user has made a mistake in storage.

In fact, as in a real warehouse, the work of each position is interdependent.

ml picking scanner fr

5. Explanation of Responsibilities

During this simulation, the user will have the opportunity to take on several logistics agent positions. These will be available during each exercise, so we will describe each of these positions in this section.

5.1. Receiving Dock

When staffing the Receiving Dock, the user’s role will be to unload the trucks using forklifts.

After that, the user will have to scan the labels on the crates and pallets taken out of the trucks using the scanner available at their workstation.

Each time the user scans a label, an “R0” label will be printed, which the user must then take and place on the scanned crates and/or pallets.

Once the pallets have been labeled, they must be placed in the receiving area.

5.2. Smalling Volume Receiving

For small-volume deliveries, the user must collect the boxes from the pallets and process them.

This task is divided into two stages: processing the boxes and storing the products.

Box processing procedure:

  1. Retrieve a box from the pallet

  2. Place the box on the work desk

  3. Open the box using the box cutter available on the work desk

  4. Scan the delivery note in the box

  5. Retrieve the labels printed when scanning the delivery note

  6. Place the labels on the products in the box

  7. Remove the products from the box and place them in a conveyor box

  2. Place the products in the appropriate bins

  3. All products have a label associated with a bin name

5.3. Large Volume Receiving

In Large Volume Receiving, the user will need to process high volumes, labeled items, and stored items.

Procedure for processing high volumes:

  1. Take the scanner from the work surface

  2. Scan the “R0” labels on the boxes

  3. Take the printed labels and place them on the boxes

  4. Send the boxes to the correct locations using the forklift truck

5.4. Stock Picking

When picking stock, the user must pick small-volume and large-volume items from throughout the warehouse.

Stock picking procedure (small volume):

  1. Take a picking box from the “Order Preparation” desk

  2. Go to Zone 1 in the small volume storage area

  3. Take the picking scanner

  4. Pick the products displayed on the scanner

  5. Return the picking box with the picked items inside.

5.5. Order Preparation

In the role of an order filler, the user will be required to retrieve previously picked products and assemble orders to send them to the correct recipients.

  1. Retrieve the picked products

  2. Sort the products by order

  3. Select an order

  4. Move the products to the loading docks associated with each order’s destination

    1. For small volumes: Take a picking box.

      1. Fill this box with the small volumes related to the order

      2. Call a Mobile Storage Unit (MSU)

      3. Place the box on the MSU

    2. For large volumes:

      1. Use a forklift to move the crate

  5. Go to the shipping area

  6. Send the products using the computer
