Mechanical arm, alike people’s arms, could execute a series of postures. At present, many mechanical arms can’t be operated flexibly because of the change of environment and distance.

On tackling this problem, KEYES group has launched a 3 in 1 learning kit-4DOF mechanical robotic arm car. With this kit, you could acquire how to control mechanical arm and smart car. I believe that you can’t help opening it to get started.



3 in 1 Design: Smart car, mechanical arm, mechanical robot arm car Multi-purpose Function: obstacle avoidance, follow, remote control and automatic convey.

Easy to Build: Soldering circuit is not required.

High Tenacity: high performance baseplate and metal mechanical arm

High Extension: expand other sensors and modules through motor driver shield.

Multiple Controls: PS2 joypad control, fully automatic and App control(iOS and Android system)
