RAD206-FinalProject

Software:

• This project was created using Unity 2020.3.19f1 and Arduino version 1.8.10

Hardware:

• This project used a HoloLens 2 developed by Microsoft Corporation found at: https://www.microsoft.com/en-us/hololens/hardware
• The microcontorller used for servo control is the Arduino Mega 2560 Rev3 found at: https://store-usa.arduino.cc/products/arduino-mega-2560-rev3?selectedStore=us
• The servos used for development were the Hextrinik HXT500 6.2g 0.6kg .08sec Micro Servo found at: https://www.amazon.com/gp/product/B00WFHMXHY/ref=ppxyodtbsearchasintitle?ie=UTF8&psc=1
• The rack and pinion mechanism used to provide normal forces to the user's wrist were 3D printed using the https://formlabs.com/3d-printers/form-3/
• The housings around the wrist-worn device were 3D printed using the https://www.makerbot.com/3d-printers/replicator/

Setup:

Unity Hub: - In Unity Hub, open the Unity project folder named FinalProject in the path: [your download location]\RAD206-FinalProject\Final Project

Unity Editor: - Once the Hololens 2 Holographic Remoting and Arduino serial communication is setup, press the Play button in the Unity Editor to start the simulation

Hololens 2 Setup: - This project is run using the Hololens' Holographic Remoting in the Unity Editor so that the serial communication between the Arduino microcontroller and Unity can allow the wrist-worn device to provide haptic feedback - Please follow the instructions to setup Holographic Remoting in the Unity Editor (Unity 2020 + OpenXR): https://docs.microsoft.com/en-us/windows/mixed-reality/develop/unity/unity-play-mode?tabs=openxr

• Arduino Setup:
  • Plug in the Arduino connected to your servo-driven wearable device to a USB port on your computer
    • Find the folder with path [your download location]\RAD206-FinalProject\Final Project\UnityArduinoComms and open the file UnityArduinoComms.ino
    • Download the program to the Arduino and make note of the COM port being used
    • In the Unity Editor, find the script SerialComms.cs in the file path Assets\Scripts
    • One line 13 of SerialComms.cs, change the String variable to "COM[#]" where "[#]" is the number (e.g. "COM3") of the COM port used to upload the UnityArduinoComms.ino program to the Arduino
    • Recompile the project in Unity Editor and ensure the change was made by checking the "Port Name" public variable attached to the GameObject "Needle"
