Issues experienced with µArm, for use when designing improved firmware and hardware.

µArm issues

Firmware

  1. Resets unpredictable during movement series (such as hanoi.c).
  2. Pushes servos into mechanically limited positions.
  3. No collision detection despite servo position feedback, sucker contact button.
  4. No state display on LEDs.
  5. Servos move at high speed, stressing mechanism and overcoming base friction.
  6. Position based around servo settings rather than head position. Stretch and height coordinates are not independent.
  7. Many serial libraries don't function (eg RubySerial), forced to use specialised arduino-serial library.
