• Lockdown period gave me some time to add the stomach and develop the interface. Our “Ultron” has a Raspberry Pi V4 with NodeRed as master, an Arduino Uno plus two PCA9685 servo shields. Communication between Pi and Arduino is established via Serial over USB and works fine. Still a lot to do…

    Yes Steve, and the true work seems to start on the soft(ware) part. I decided to use Arduino shields, a Raspberry PI4 with Node Red and Serial Communication via USB to connect both platforms – boy this is really challenging my software development skills. But its fun – and I consider it a marathon.

  • Assembly of major parts finished, all servos tested – programming can start!

    • Looking good. It makes me realise just how much work I still have to do.
