It was never going to be strong enough as a robot arm, so they turned it around and made it into an interface device. The amount of room needed for the linkages to move around is not practical.
On the plus side, it’s got a lot of the hardware that robots use and may serve as a great education for people starting out in the field: encoders, position sensors, DC brushless motors, control, and more.
Makes life easier by cleaning up all those messy wires in your prototyping. hanging off the side makes it easy to fit in a two part, 3D printed case. We use it as part of development for our Sixi Robot Arm.
You can get all the details and order them for you or a friend right now.
From any web-enabled desktop browser you can experiment with the kinematics of a robot arm at http://robot.glumb.de/
The author, Maximilian Beck, has made all the code available online at https://github.com/glumb/robot-gui. Be sure to check out his other interesting projects on github, too.
