Liquid-Slosh Balancing Robot

Mobile platform carrying an open half-full liquid payload without spilling. Mobile platform carrying an open half-full liquid payload without spilling.

Components

  • ESP32 or Teensy
  • IMU
  • load/spill sensor
  • geared drive

Build steps

  1. Inventory the board, actuators, sensors, and power rails listed for F01.
  2. Build and inspect the low-voltage wiring against the supplied connection diagram before connecting actuators.
  3. Flash the firmware, run the startup self-check, and record the printed board and firmware version.
  4. Calibrate the sensors and limits, then run the acceptance tests at the lowest safe energy level.

Test and expected result

Characterize slosh, baffles, center-of-mass shift, IMU filtering, and spill threshold.

Safety and limits

No-spill threshold must be measured; use a tether and low-speed first tests.
