Overview: 

1. The most economical and fun robot car kit.

2.  With simple mechanical structure, a nice system and very easy to install.

3. Code with the tutorial which bring you to the robot car world. 

4. The ultrasonic sensor to keep the car way from barrier. 

5. Use the UNOR3 control board to meet demands of different users. 

Description: 

1.The main body of the chassis is made of Laser-Cut Clear-Acrylic sheet and can hold two gear motors
on either side and a supporting universal Castor wheel. 

2.It also holds a compartment for four AA batteries (not included) with battery terminals that protrude
through the chassis and can be accessed from the top. 

3.Each dual shaft motor has one side holding the wheel while the other is connected to an encoded disk.
The chassis has enough holes and openings for mounting Sensors, Servo, Motor Drivers, and control modules. 

4.This kit can be used to build a robot for distance sensing, Obstacle Avoidance, Line follower, Flame Detector,
Speed Tester, Wireless remote controlled Car, and any other creative works. 

Feature: 

Simple mechanical structure and easy installation. Smart robot car with code and ideal for DIY.

Using for distance and speed measurement due to the tachometer encoder with the car. Multi-function and various
kinds of positioning holes for all kinds of modules. Controlled by the UNO R3 Development Board,Ultrasonic sensor
to achieve obstacle avoidance function. 

Notes: Come with a 4 AA battery box (batteries not included). The car Chassis is transparent; you need to tear out
protective paper. Due to the difference between different monitors, the picture may not reflect the actual color of
the item. We guarantee the style is the same as shown in the pictures.
