HeadpatVR
Device that brings tactile feelings of VR head pats using mechanical force applied by brushes
[!WARNING] This project is in the development phase. Please note that components of the project are subject to frequent changes
Introduction
Feel VR head pats in real life!
This device monitors hand contacts with a head in VRChat and reproduces cuddles on a head in real life using brushes controlled by servo motors
Inspired by a similar project that uses vibrating motors Why another version? I found vibrations on a head too unpleasant and decided to try to reproduce head pats in another way
Project parts
Server
This repository includes only the server application that should be launched on the PC along with VRChat. The server communicates with VRChat application using OSC protocol (you can find more details about VRChat OSC here) It doesn't have UI but provides useful logs to give you an understanding of what's going on
Firmware
The source code is available here The code is written based on Arduino framework
Hardware
- 2 servo motors
- ESP-WROOM-32 38pin board
- esp-32 expansion board
- fasteners
- silicone brushes
- mount system for the motors
- mount system for esp-32 expansion board
- power supply
The detailed list of parts with description can be found here
Setup
Firmware
The documentation and source code of the firmware can be found here You need PlatformIO IDE to compile and upload it to your esp32-based board
Hardware
Since there are only 3 electronic components, the wiring is simple
You can use a regular power bank as a power supply by connecting it to the expansion board. Make sure that the board jumper is in the right position (in the 5V position) This is the minimal device setup to do basic tests
The motors with brushes and the board should be mounted on the VR headset with the help of additional printable plastic parts The latest assembly instructions can be found here:
Server
The latets binary file can be downloaded from the Releases section
Alternatively, you can build it locally. Download repository, install Python and execute the build.bat file. The executable file will be located in the dist folder
Preparing VRChat avatar
Follow the instructions described in the Patstrap project documentation's VRChat section: https://github.com/danielfvm/Patstrap?tab=readme-ov-file#vrchat
