Fail of the Week: Good Prosthetic Hand Design Goes Bad

Is this a case of a good design gone wrong in the build phase? Or is this DIY prosthetic arm a poor design from the get-go? Either way, [Will Donaldson] needs some feedback, and Hackaday is just the right place for that.

Up front, we’ll say kudos to [Will] for having the guts to post a build that’s less than successful. And we’ll stipulate that when it comes to fully articulated prosthetic hands, it’s easy to fail. His design is ambitious, with an opposable thumb, fingers with three phalanges each, a ball and socket wrist, and internal servos driving everything. …read more

Robotic Arms Controlled By Your….. Feet?

The days of the third hand’s dominance of workshops the world over is soon coming to an end. For those moments when only a third hand is not enough, a fourth is there to save the day.

Dubbed MetaLimbs and developed by a team from the [Inami Hiyama Laboratory] at the University of Tokyo and the [Graduate School of Media Design] at Keio University, the device is designed to be worn while sitting — strapped to your back like a knapsack — but use while standing stationary is possible, if perhaps a little un-intuitive. Basic motion is controlled by the …read more

Ardu McDuino Plays the Bagpipes

To “pipe in” the new year, [John] decided to build a bagpipe-playing robot. Unlike other instrument-playing robots that we’ve seen before, this one is somewhat anatomically correct as well. John went the extra mile and 3D printed fingers and hands to play his set of pipes.

The brains of the robot are handled by an Arduino Mega 2560, which drives a set of solenoids through a driver board. The hands themselves are printed from the open source Enabling the Future project which is an organization that 3D prints prosthetic hands for matched recipients, especially people who can’t otherwise afford prosthetics. …read more
