We present theory and measured performance of an autonomous slot car driven by a heuristic algorithm on a typical track. The hardware consists of a PIC 8-bit single-chip microcontroller with various sensors driving a standard permanent-magnet (PM) brushed dc (BDC) motor in a mechanically-standard Scalextric platform. We present some interesting results concerning the relative difficulty of apparently-balanced lanes on a track. The car achieves optimum lap times with high consistency. Measured performance agrees with theoretical expectation. The consistency of performance allows the impact of experimental changes to be reliably assessed.
