For several years, most of the robots were controlled by MIDI-to-voltage control
computers designed and built by Stock Plum, of Holland.
The "SBrain" (StockTek SN# 001) computer is capable of switching
96 actuators, as well as an additional 32 polarity switching continuous motors.
Closed loop feedback is achieved at the hardware level by a separate
positional feedback controller computer, also designed by Stock Plum.
This computer is used for driving such robots as the
"Geck" voice box and the "Electro Drummer",
which both require positional feedback to operate.
Both of the control computers interpret MIDI data and translate
that information into voltage switched signals which are sent to the robots.
