Here’s an interesting open source project on Kickstarter the MeArm, a pocket size robot Arm by Benjamin Gray:
Low cost, easy to build and simple to control, MeArm is designed to make learning with robotics accessible for everyone.
MeArm is a pocket size robot arm. It was conceived to make robotics, electronics and programming accessible – by driving down the cost of robot arm ownership. The ultimate aim is to make something low cost that you can build with nothing but a screwdriver and enthusiasm.
Apart from being something that’s small, cool and attractive the MeArm is a miniature version of an industrial robot arm. So while it’s simple enough to build and use with a child on a rainy Sunday afternoon – it can also be used at more advanced levels of education to teach real robotics.
Design and code files are available on Github.
