very nice work, I installed last night,, works great, I see two bugs,
1. facing robot, turn my head, the robot not turn head, but turn both arms,
2, back facing robot, waving arms, turn head look at robot, sometime the robot's arms are stuck inside the body.
nice to have a reset button on the table.
I can help testing too, I can test using different version unity, god knows how many different versions I got installed.
