The (Robot) Body Electric

If you deal with electronics, you probably think of static electricity as a bad thing. It blows up MOSFETs and ICs and we take a lot of pains to prevent that kind of damage. But a start-up company called Grabit is using static electricity as a way to allow robots to manipulate the real world. In particular, Nike is using these robots to build shoes. You can see a demo video, below.

Traditional robots use human-like hands or claw-like grippers to mimic how humans handle material. But Grabit has multiple patents on electroadhesion. The original focus was wall-climbing robots, but …read more

Hackaday Prize Entry: A Six Axis Robotic Arm With Fingertip Control

If you were a child of the 1980s whose fascination extended to the contents of your local Radio Shack store, you may remember the Armatron robot arm as a particular object of desire. It was a table top robot arm operated not by motors or a microcontroller, but by a clever set of gears directed manually from a pair of joysticks. If you took a look at it with an eye to control from your 8-bit home computer you were likely to be disappointed, but nevertheless it was an excellent toy.

The Armatron may be long gone, but if you …read more

Evezor Robotic Arm Engraves 400 Coasters

When you’re running a Kickstarter for a robotic arm, you had better be ready to prove how repeatable and accurate it is. [Andrew] has done just that by laser engraving 400 wooden coasters with Evezor, his SCARA arm that runs on a Raspberry Pi computer with stepper control handled by a Smoothieboard.

Evezor is quite an amazing project: a general purpose arm which can do everything from routing circuit boards to welding given the right end-effectors. If this sounds familiar, that’s because [Andrew] gave a talk about Evezor at Hackaday’s Unconference in Chicago,

One of the rewards for the Evezor …read more

Tying Knots with Industrial Robots

We’re not ashamed to admit that we desperately want a pair of high-end industrial robot arms to play around with. We don’t know where we’d put them — maybe the living room? — but we know that we’d figure something out.
This demo aims to get Boy Scouts interested in robotics by applying the beastly arms to something that all kids love, learning to tie knots. (If you ask us, they’ve got it backwards.) Anyway, there are two videos embedded below for you to peek at.

In case you haven’t thought about knot tying, it’s actually a neat problem for …read more
