Holio II

Holio II is a "rebuild"

We started with the wheeled motion base of Holio and added a fully articulated sensor array. Essentially this is a test bed for sensor technology. It has a video camera, a sharp IR distance sensor and an ultrasonic sensor. It is driven and powered down a cable system - basically any serial cable will work. The 9 volt battery powers the PonTech servo controller board as servo activation causes it to reset frequently. (This is very typical with this controller. The designers did a smart thing and put in a cutable foil to separate the power supplies but it seems like some well placed diodes and a capacitor would save us used some trouble.)
