Description

A flat, no-fuss line-follower deck in the spirit of a bare-bones racing sled: one smooth plate, wheels tucked at the rear, and a sensor bracket reaching out front. Built around an Arduino Uno, with four solid standoffs matching the Uno R3 hole pattern.

Design notes

  • Plain flat baseplate with no fastener holes or slots
  • Openings only for the two wheel cutouts and the sensor tray window
  • N20 motor cradles at the rear, shaft notches kept
  • Four solid Uno standoffs for a 68.6 × 53.3 mm board, long side across the chassis
  • Front sensor bracket with a 126 × 26 mm board shelf
