We bought an old electric wheelchair for about £100. The motors and electronics were taken from this and kept safe for later. We then started to make a steel frame and weld it together. Diagonal cross members were welded on and the motors were fastened into place. Weight was going to be a problem for us, although the limit was increased to 100Kg this year. The frame and shell of our next robot will almost certainly be aluminium
		A lot of welding and grinding was carried out. We are fortunate that we are able to use the workshop at our factory in the evenings.
	A plate was then fastened to the bottom so that we had somewhere to locate the batteries, electronics, and of course the piston for the flipper.
		We then made another frame for the jaws of our Wolf, and cut out panels to fit on the side. Next the wheelchair electronics were fastened into place, an old CO2 fire extinguisher was used to power the flipper, and our radio control was tested to make sure we had no interference problems. The large red gear wheels were driven by radio control servos.
	These gears moved smaller gears attached to potentiometers. The resistance change was used to vary the input voltage to the speed controller. Depending on the position of the gears the controller would deliver between 0 - 24 volts DC to the motors.
	Before long the robot was taking shape. A coat of paint made it look much better and we were nearly ready for our first battle.
