As a controls engineer, I have wanted a way to share a real example of how a real industrial controls system is designed without sharing company property. The AR4 robot seemed like the perfect platform to enable me to do this because robots are fun to play with and the cost of the AR4 is super inexpensive – making the cost of ownership within reach for almost everyone. So I created ArfBotOS as a complete operating system for this robot and shared it open source for anyone.
