In this project, we will show how to use Arduino to control an Osoyoo Brand Mecanum wheel robot car.
OSOYOO UNO board or MEGA2560 board fully compatible with Arduino UNO/Mega2560 x 1
OSOYOO V1.0 Wifi Shield x 1
Mecanum Wheels x 4 (2 left-wheels and 2 right-wheels)
GM37 Stepper Motor x 4
OSOYOO 4-channel motor driver board
Chassis x 1
HC02 Bluetooth Module
screws and jumper wires
18650 battery x 2
battery box x 1
