The power with which this unit can drive a heavy-duty motor
is astonishing!

Some years back the author was bitten by the bug to build a radio controlled combat robot. Plans were laid and the mechanics were built with a lot of work from a team of three engineers including himself.

The classic wedge shape robot was born with a pair of 24V d.c. permanent magnet electric motors, previously used on an electric wheelchair. These were needed to supply drive for the robot. Mild steel square section tubing and a few square metres of 3mm aluminium sheeting was also used in the construction.
