What it can do

Written by Robotheca from the project's documents.

  • Designed as a small 50 cm, 4 kg humanoid inspired by ROBO-ONE, capable of agile movements, combat-oriented sequences, and dance moves.
  • Servo calibration tool maps intended angles to actual PWM pulse widths in microseconds for each servo.
  • Calibration tool works on 180-degree servos; 270-degree servos can be calibrated with adjusted +/-135 degree marks.

Wiring and electronics

Notes written by Robotheca from the project's documents.

Main parts

  • Commercial off-the-shelf servos, which the robot is built around.
  • Arduino board used as the controller for the servo calibration tool.
  • External power supply set to servo voltage (typically 7.4 V) for powering the servo during calibration.
  • ESP32 controller is mentioned as a planned optimization target in the to-do list.

Connections

  • For servo calibration, the servo signal line connects to Arduino pin D7 and the servo ground connects to GND.
  • The servo is powered from an external PSU at servo voltage rather than from the Arduino.
  • A standard wiring convention is still in progress; the repository points to a wiring diagram image for now.
