Mechanical and electrical

Building the robot

Plywood, two gearmotors, three mechanisms, and a front skid cut from a plastic spoon.

Phase 1 skeleton. This page will contain:

  • Radical simplification: triangular chassis on omni wheels → a rectangle of plywood
  • Three mechanisms: compost rotator, lever arm, window extension
  • The lever arm doing double duty — apple bucket and fertilizer levers
  • The plastic spoon skid
  • Drivetrain analysis: 178in path, torque-speed curves, 14.04° ramp
  • Electrical system and wiring
  • Budget: $160 allotted, $36.99 remaining
  • CAD drawings, exploded views, and build photos
