1. The main control board adopts Arduino CH340 Development Board.
2. Motor driver module uses L293D module to drive DC motor.
3. BT Wireless Module HC-06 connects the module through mobile phone APP and sends control instructions to realize the motion control of smart car.
4. The ultrasonic sensor module adopts HC-SR04 module and adopts ultrasonic distance measure sensors to measure the distance between the car and the obstacle. When the distance is less than the set obstacle avoidance value, change the direction to realize the obstacle avoidance function.
5. The chassis of the trolley is made of aluminum alloy, which is light and thin, not easy to deform and firm.
6. Mecanum wheel is used as a wheel to make the car realize all-round movement.
