AR4 6 Axis Robot Arm

This 6 axis robot arm uses an Arduino based controller and Python interface programming as well as RoboDK. The AR3 & AR4 have been used in hundreds of hobby, educational and STEM programs to teach mechatronics, machining, 3D printing as well as programming. This desktop robot arm has also been used for a wide variety of industrial tasks such as welding, sorting, stacking and machine tending and has also been used in many filming and videography applications.
