Arduino-powered, Smartphone-controlled, 3D Printed Robot arm

Hi guys!

We're developing a 3D printed robotic arm maker kit you you can control from your smartphone!

We've got a cool timelapse video of the build here.

It will come with a full set of of instructions and a gameified learning platform that teaches you how to make your kit and engages you with some of the science behind the electronics. The arm is controllable from your smartphone with our special Maker Connect chip.

We've got an IndieGoGo campaign launching pretty soon (you can read about that here), so any input is greatly appreciated!
What would you like to see on a robot arm? What kind of attachments would you like?

Thanks guys, glad to become a part of your community
