4-Wheel Differential Ackerman Smart Car Kit Line Following Car with 51 or STM32F103C8T6 Board Option

* 4-wheel differential car: Its movement is similar to that of a tank. It can be used for low-speed movement and can turn on the spot.

* Ackerman car: It adopts a car-like structure, and the front wheels are controlled by a servo to turn, which can be used for turning at high speed.

* Mecanum wheel car: Omnidirectional movement. It can move sideways and turn on the spot. The algorithm is slightly more complicated.

* Multiple movement forms

* Easy assembly

* Small and flexible

* All-metal gears: long motor life and good quality. Motors come with motor wire and no need to weld.

* Three-layer large space for easy expansion: reserved holes meet a variety of common components, making it convenient to DIY

* Four-motor drive makes the control more flexible

* The front part of the car has reserved holes for a dot matrix screen

* Motor model: N20 DC reduction motor

* Rated voltage: 6V

* Rated speed: 400r/min

* Rated current: 70ma

* Servo model: SG90

* Servo torque: 1.5kg/cm

* Servo running speed: 0.3s/60°

* Servo line sequence: dark gray for GND; red for VCC; orange for pulse input
