Automatic Cheese Grater

Designed and built an affordable, fully-automated cheese grater for home kitchens, aiming to replicate commercial performance in a compact, user-friendly package. The system integrates dual-motor actuation (compression and grating) with feedback control for fully automated operation.

My Role

  • Led prototyping and mechanical integration of the motorized compression and grating system
  • Developed the control logic and feedback loop (motor, encoder, and button integration using ESP32)
  • Conducted load, torque, and safety factor analyses to optimize mechanical design
  • Performed extensive testing and refinement to ensure repeatable, smooth operation

Impact

  • Push-button interface and reliable state machine for user-friendly use
  • Lead screw mechanism applies controlled force matched to cheese consistency
  • Total bill of materials under $400—substantially less than existing commercial solutions
  • Lessons in state machine design, physical manufacturing, and iterative testing
