Evolutionary Building Forms
Wall-E Robot., Four leg robot, Robot Penguin, Walking Robot, Three Wheel Car, Detection Robot.
Easy but Powerful WeeeCode, Support Scratch & Arduino Programming

WeeeBot Evolution is fully compatible with WeeeCode which is a graphical programming environment based on Scratch 3.0 Open-Source Code. It makes programming projects and interactive applications easier through simply dragging and dropping function blocks.

Learning programming is way more fun when your code controls a robot. Based around an Arduino board, this kit will teach you all about programming a micro-controller board to control physical objects using sensors.
Control and Code by One Touch
WeeeMake APP is a control and program application designed for Weeemake robot. It provides six modes to play with your robot such as manual control, line-following, obstacle avoidance, music, voice control, and coding.
 
Easy Wiring
Modules in this kit all equipped with RJ11 ports for easy wiring. Just by connecting the modules together, robots can be built in a really quick way. All the wiring is simple and very clean.

RGB Ultrasonic Sensor
The RGB ultrasonic sensor is an electronic module used to measure the distance with a measurement range of 4 cm to 500 cm. It can be used to help a car avoid obstacles or other projects related to ranging. The ultrasonic transmitter send ultrasonic wave in a certain direction and start counting time. The ultrasonic wave spreads in the air, and when the obstacle is encountered on the way, it returns immediately. The ultrasonic receiver immediately stops timing while receives the reflection wave. The transmission speed of the sound wave in the air is 340m/s. According to the time (T) recorded by the timer, the distance (S) between the transmitting point and obstacle is calculated, that is, S = 340*T/2.

At the same time, both ultrasonic probes has an built -in RGB LED light.

Double-way Line-following Sensor
The line-following sensor is using the feature of infrared that will get different reflection strength on the difference color surface. During the driving process of the robot car, the line-following sensor continued to transmit infrared light to the ground. When infrared light encountered a white surface, a long reflection occurred and the receiver on the sensor will receive those reflected infrared; When infrared light encountered a black surface, the infrared light is absorbed, and sensor’s receiver cannot receive infrared or receive very few. The position of the black or white line is determined by whether to receive the infrared light returned from the reflection or not.

The double-way line-following sensor has two groups of infrared transmitter and receiver tube S1, S2.
