Keyestudio Mini Caterpillar Tank Robot V3.0


This STEM educational V3.0 tank robot is newly upgraded, adding an line-tracking and a fire- extinguishing function. It vigorously enhances the relationship between kids and parents, and sparks children’s imagination through programming and coding.

In the course of assembly process, you can see its multiple functions like light following, line tracking, IR and BT remote control, speed adjustment and so on. Additionally, there are some small parts that can help you assemble the robot car.

There are basic sensors and modules, such as a flame sensor, a BT sensor, an obstacle avoidance sensor, an line tracking sensor and an ultrasonic sensor are included.

The two tutorials for C language and Arduino are also suitable for the enthusiasts at different ages.
