The newly upgraded 4WD Multi-purpose car is one of the most popular Arduino sets. It not only has a beautiful appearance but also powerful functions. In addition to the usual functions of line tracking, obstacle avoidance and remote control, it also uses facial expressions to make lovely expressions. Furthermore, you empower to expand your own projects, or add other sensors to complete your exploration.

Most of the components are connected via screws and copper pillars, thereby you can build your own robot through a few simple assembly steps. What’s more, the basic knowledge such as line tracking, obstacle avoidance sensors, ultrasonic ranging, Bluetooth communication, motor drivers as well as IR remote controls are accessible for us to learn. This product boasts 17 learning projects, from simple to complex, which will guide you to make an Arduino robot.
