Abstract (en)
Apparatus for controlling the motion of miniature vehicles along a track comprises power supply means including an oscillator (B1) and a frequency divider (B2) for supplying a signal comprising a plurality of different frequency component signals via spaced conductive strips on the track to the miniature vehicles. Each miniature vehicle carries two band pass filters each arranged to allow only one of the different frequency component signals to be supplied to respective switching means (T1, T2) controlling operation of a corresponding drive motor (M1, M2) arranged to drive a respective one of two drive wheels of the vehicle to control the motion of the vehicle on the track.
