An Arduino-powered 4-axis Parallel-mechanism Robot Arm

IMG_7859x.jpg
uArm is a miniature 4-axis parallel-mechanism robot arm, modeled after the ABB PalletPack IRB460 industrial robot arm.

It is made up of laser cut acrylic or wood parts, powered by standard RC hobby servos, and controlled by an Arduino-compatible board.

The basic design is Arduino-controlled, using 4 servos, with 4 degrees of freedom. Three servos on the base control the main movement of the arm and the last servo on the top moves and rotates the object.


uArm can be controlled with keyboard or mouse easily.


Using mouse to control uArm to play Cup Stacking via serial.


Now we are on Kickstarter, you can see more details about this robot here.
