Out Of Stock



4WD Multi-purpose car is One of the most widely used Arduino sets that has recently been upgraded. It not only has a stunning appearance, but it also performs well. It performs the typical tasks of line tracking, obstacle avoidance, and remote control in addition to making beautiful expressions using facial expressions. Additionally, you have the freedom to develop your own projects or incorporate new sensors to complete your investigation.

The majority of the parts are connected by screws and copper pillars, so you can construct your own robot by following a few straightforward assembly steps. Additionally, we can learn the fundamentals of line tracking, obstacle avoidance sensors, ultrasonic ranging, Bluetooth communication, motor drivers, and IR remote controls. This product offers 17 educational projects that will help you build an Arduino robot and range in difficulty from simple to difficult.

Package Includes:




1. Multi-purpose function: Obstacle avoidance, following, IR remote control, Bluetooth control, confined with a circle, gravity control as well as facial emoticons display.
2. Simple assembly: No soldering circuit is required, simple assembly.
3. Sturdy construction: 4WD construction, 4 premium motors, and wheels.
4. High extension: It can expand other sensors and modules via a motor driver expansion board
