Robotic arm body is made of aluminium alloy featuring lightweight and high strength. 5DOF compact and flexible body design enables you to mount it on your desktop.

The integration of 120° wide-angle camera and flexible robotic arm provides ArmPi mini with expanded field of view. This camera supports manual focus making it handy for use.

Robot base adopts full-metal high torque servo with metal servo horn which brings stronger force. And robotic arm end uses micro anti-blocking servo with high accuracy and longer service life.

Always excited when Hiwonder comes out with a new Raspberry Pi kit as I buy it. This one comes with only a small amount of assembly required. The arm itself comes assembled as they felt it might be too complicated for their intended audience. You just have to assemble base and controller. I got bought this to help me learn about A.I. and coding and so far i like it a lot very good.
