A remote-controlled bot which designed to pass an obstacle course.
This repo aggregates all the files needed to build it yourself.
The key trait of the bot is a steering wheels system. As soon as there is no differential, each of the wheels is attached to a separate motor and "inner-outer" wheels rotating difference is obtained programmatically.
- Servo shouldn't be powered from the Arduino board, doing this will cause the board to restart on each turn (and to loss control).
- 3D-printed wheels are quite slippery, you may want to cover edges in hot glue or chose other shape/material.
- The rear of the bot definitely lacks something of ball-wheel kind. Without it bot tends to hook everything below it.
- Chasis and wheels are 3D-printed (STLs are in the repo)
- 7x bearings 10x5x4
- 2x DC motors
- H-bridge (e.g. Amperka Motor Shield)
- Servo
- 2x Arduino UNO (bot + transmitter)
- Batteries
- Receiver-transmitter pair
- Joystick
