Picture of An Arduino-powered 4-axis parallel-mechanism robot arm
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.

Hello! We are university students (Colombia)

Can we get the sources files (design) for print the materials?

We hope that you can help us! Thanks!

as I can find measures cadaq piesa recomiedan paging me to know

searching for plans and I found this. for an open source piece of hardware, very little has been released. when and where will the plans be available? Could you make an edition that is not in CAD so that those of us without CAD can still play with the designs?

Hi! Nice project!! Is it open source? Is it possible to download the plant? I've searched on your website, gitHub and Open Source Hardware websites but didn't find it.


Awesome Project !!
How can i buy this robotic arm. i am very much interested to integrate it with my UGV.
