How to make a simple dynamic balanced vehicle
This is a simple dynamically balanced vehicle.Williamson writes:The only really exotic component is the motor/gearbox: it is a high impedance motor with a 62:1 epicyclic gearbox and cost ?7. A cheaper option is to use a mabuchi solar motor without any gearbox at all, a walkman motor would also probably work although I haven’t tried it. Use a wheel just slightly
bigger than the motor body to maximise torque. One-wheel drive is important because the correcting force must be applied at the end of the dowel. If you use two wheel drive the sideways wobble of the mast puts all the weight on one wheel or the other and the vehicle spins about the axis of the mast. The undriven wheel provides sideways balance, like an outrigger, without exerting any steering force.
