This page is about the electronics assembly. Check out the main project index for the rest.

There are some videos about this section:

The main microcontroller is an Arduino Mega. It probably doesn’t need to be that, but there’s lots of space. I’m also using four Arduino Pro-minis which will each handle two PID motor controllers. The Mega will be the master device – the Pro-Minis will be slave devices on a common serial bus.

The motor drivers are BTS7960s – there are nine of them including eight for the legs motors and one for the front/back waist action. The remote is largely button based to trigger routines on the Droid, apart from one slide control which will alter the angle of the waist/box. The remote is Bluetooth using HC-05 modules.
