This is a controller program for a hexapod (six-legged) robot. Mechanical design of the robot can be found here: https://github.com/SmallpTsai/hexapod-v2-7697. Electronics and software is custom.
- Control algorithm running in soft real-time under Raspbian Lite on Raspberry Pi Zero W
- Movement on three axes: Forward-back, sidewards, and left-right turn
- Adjustable movement speed
- Adjustable body height and attitude
- Adjustable leg lifting height
- I2C communication with two Waveshare Servo Driver boards (PCA9685) to run a total of 18 servos
- I2C communication with an Arduino Nano to read command signals from a Sanwa SD-10G radio controller for remote control (Arduino code available at https://github.com/Valthoron/arduino-rc-sampler-interrupt)
- XML-based configuration file for servo calibration
Main controller routine is python3 Main.py.
To calibrate servos, python3 ServoCalibration.py commands all joints to preset angles and continually reads the configuration XML for bias values.
