When [Robert] realized Adafruit is now selling analog comments servos, he decided he just had to make a programmable robot arm that might be trained like the commercially offered Baxter robot.

The neat thing with the analog comments servos is it takes all the complexity out of training a robot. All you have to do is put the robot in teach mode, physically move the robot’s joints to the positions you want, as well as save your program! depending upon your application, it definitely beats trying to work out the fun kinematics equations…

Anyway, the full guide offered on Adrafuit’s discovering system provides directions on exactly how to develop your own arm from scratch (well, with a 3D printer) or exactly how to replace the servos in a pre-made toy robotic arm you may already have sitting around. It’s extremely comprehensive as well as includes all the code you requirement for your Arduino too.

Stick around after the break to see exactly how the robot works!
