j-be/vj-servo-controller

A Python server providing a SocketIO interface and a wrapper for Maxon EPOS2 servo controllers.

Introduction

This repo contains:

• The Python based server meant to run on a RaspberryPi 2 (root folder)
• The Arduino sketch for the servo position detector (Arduino folder)
• The schematic for the additional PCB (hw folder)

The server

Development environment

Within the development environment both the servo and the Arduino are mocked.

Requirements

• Python 2.7
• (Windows only) Install the VC++ compiler for Python 2.7 (http://www.microsoft.com/en-us/download/details.aspx?id=44266)

Setup

I recommend using pip and virtualenv. One way to do so is:

1. Download PyCharm (https://www.jetbrains.com/pycharm/download/) - Community Edition is sufficient
2. Open this repository
3. Set interpreter to Python2.7
   1. Go to "File" -> "Settings"
   2. Search for "Interpreter"
   3. Set to Python 2.7
4. Open epos_control_server.py
5. PyCharm should now display that some requirements are missing -> click "Install requirements"

Run

python epos_control_server.py

Production

Ready-to-use SD card images can be built following the instructions at https://github.com/j-be/vj-control-server-buildenv

Arduino

Download the Arduino IDE (https://www.arduino.cc) and follow the usual Arduino procedures as described at https://www.arduino.cc/en/Guide/ArduinoUno.

Unity3D

The API can be found at https://github.com/j-be/vj-unity-apis. Follow the instructions there. For this server you need:

• AbstractSocketioClient.cs
• ServoControllerClient.cs
