Abstract
The system uses an electric accumulator and reversible motors with reduction gears mounted by means of clamping collars on the chair framework. These can have rollers of semi-flexible moulded plastic which are ribbed and which transmit the drive to the tyres without wear. The motors can be of very low power, absorbing approximately 20 watts, with an output speed of 60 r.p.m. or so. Thus travel speed is approximately 15 metres per minute, providing a self-braking effect, so that it can be used by a paraplegic. The complete system including the accumulator weighs less than 18kg.
