I have one robot plataform, metal and rigid.
I want use this in off road, more interesting :-)
But with rigid chassis no good performance on off road.
Because this I made my first robot plataform, 3D printed, with off road crawler suspension.
And I made one firmware in ESP32 Arduino, with advanced features:
- Web control (not need an app, just one browser)
- Car control by virtual joystick (It is good due you do not need to see the screen to touch the control buttons and very fun)
- Another virtual joystick to control the servo of camera
- Slow speed mode, using PWM over PWM, to give slow speeds but high torque.
- And More....
See it on action (off road):
