Arduino Raspberry mcnamara wheel smart car

LC Arduino mcnamara wheel SMART CAR

sku  :LC-Smartcar-PCB-MW-PS2 (with PS2 remote control)
sku  :LC-Smartcar-PCB-MW  (without  remote control)


I. Overview
LC Arduino Mecanum wheel car adopts PCB with mechanical strength superior to acrylic as the chassis of the trolley, Arduino UNO as the main control MCU, with 4-way H-bridge L298N motor drive module and Mecanum wheel.
It can comply conventional forward, reverse, turn and horizontal tire translation functions .
It is suitable for group programming practice of electronic enthusiasts and students, making programming full of fun!

hardware introduction and description
1. Component introduction

1. PCB chassis;
2. Arduino UNO R3 main control MCU;
3, 2 rechargeable 18650 batteries (not include );
4, L298N motor module: can drive 4 motors forward, reverse, stop;
5. Mecanum wheels: including 2pcs R wheels + 2pcs L wheels, which can achieve horizontal movement;
6. Infrared obstacle avoidance module: When the obstacle is detected, the indicator light is on and outputs low level;
7, HC-SR04 ultrasonic ranging module: used for ultrasonic obstacle avoidance;
8. Infrared tracking module: When the tracking vehicle presses the black line when the tracking module is pressed to the black line, the indicator lights and outputs a low level, so that the vehicle makes corresponding attitude adjustments;
9, SG90 steering gear: used to support the ultrasonic module;
10, DC3-6V DC deceleration TT motor.
 
11. In addition, also supports connecting the PS2 handle remote control . If you have demand can purchase it.

note :due  to shipping  not covenient ,so accessories do not include 2 knots  3.7V 18650 batteries and chargers, need purchase  in your local market .
