Abstract
A model vehicle runs on a running surface which comprises a substrate having an array of contact pins, the tops of the contact pins forming one electrode and the sides of the contact pins forming a second electrode. The model vehicle comprises wheels for running over the running surface, an electrically powered drive means, a first pick-up for engaging the tops of the contact pins, and a second pick-up for engaging the sides of the contact pins.
Claims8
A running surface for a model vehicle, comprising a planar substrate having a top surface and a bottom surface, and a plurality of contact pins projecting upwardly from said top surface, said plurality of contact pins being distributed over said top surface in a two-dimensional array, each contact pin of said plurality of said contact pins having tops forming a first electrode and side surfaces forming a second electrode.
A model vehicle for use on a running surface, said running surface comprising a planar substrate having a top surface and a bottom surface, and a plurality of contact pins projecting upwardly from said top surface, said plurality of contact pins being distributed over said top surface in a two-dimensional array, each contact pin of said plurality of contact pins having tops forming a first electrode and side surfaces forming a second electrode, said model vehicle comprising:
- wheels for engaging said running surface;
- electrically powered drive means for driving said wheels;
- and,
- a pick-up arrangement comprising a first pick-up for making contact with said tops of said plurality of contact pins of said running surface, and a second pick-up for making contact with said side surfaces of said plurality of contact pins comprising at least one elongate probe projecting downwardly to a level below bottom edges of said wheels for making said contact with said side surfaces.
