It's a Lynxmotion AL5A you have to assemble it yourself. We have 8 lever switches under the staging area we built connected to the GPIO pins on the Pi. When the Pi recognises a switch push it tells the nodejs server which passes it on to everyone.

We will post full lab notes explaining everything in detail like we did for our Halloween experiment soon!



Is the control code written in Python (which seems to be the favored language on the Pi)?


Yer the code to control the arm, listen for the lever switches and talk to socket.io is all in Python.
