DIY Programmable 2WD Smart Robot Car Chassis Kit with Motor Speed Encoder for Kids to Learn Arduino Coding Robotics and Electronics

It is really cool when seeing some robot cars wandering around, right? It is very simple. With a car platform, add some micro-controller (such as Arduino) and sensor modules, and program it. Then you made your own robot car. Features: Mechanical structure is simple, it is easy to install. This car is the tachometer encoder. Application: Can be used for distance measurement, velocity. Can use with other devices to realize function of tracing, obstacle avoidance, distance testing, speed testing, wireless remote control. Product Description 100% Brand New.
