Researchers Squeeze Out a New Breed of Robot Locomotion

Researchers have been playing around with various oddball forms of robot locomotion; surely, we’ve seen it all, haven’t we? Not so! Lucky for us, [researchers at Stanford] are now showing us a new way for robots to literally extrude themselves from point A to point B.

This robot’s particular motion for mechanism involves unwinding itself inside out. From a stationary base, a reel caches meters of the robot’s uninflated polyethylene body, which it deploys by pressurizing. Researchers can make full 3D turns by varying the amount of inflated air in outer control chambers. What’s more, they can place end effectors …read more http://pje.fyi/PrbrQl

LED Princess Dress Also Lights Up Girl’s Face

We’re pretty sure that [Luke] took Uncle of the Year last Halloween when he made an RGB LED princess dress for his niece. He recently found the time to document the build with a comprehensive how-to that’s just in time for Halloween ’17.

[Luke] made the system modular so that his niece could use it with any dress. The RGB LED strips are actually fastened down the inside of a petticoat — a fluffy, puffy kind of slip that’s worn underneath the dress. The LEDs face in toward the body, which helps diffuse the light. [Luke] first attached the strips …read more http://pje.fyi/PrWjVB

Modern Strongman Games Test Your Speed Instead

Step right up! What would a Makerfaire be without some carnival games? And being a Makerfaire, they could of course be modernized versions. In [avishorp]’s case, he made a series of games that test your speed and look very much like the old strongman game, aka high striker or strength tester.

In the strongman game, you smash a lever with all your might using a hammer. A puck on the other end of the lever then shoots up a tower, hopefully high enough to hit a bell, winning you a prize. In [avishorp]’s games the puck, tower and bell are …read more http://pje.fyi/PrTxjq

Teletype Machine Resurrected

A teleprinter is, at its heart, an automatic typewriter.  It’s electrically controlled and has some smarts to be able to decode an incoming message and has something that will move the keys.   These printers have been in use since the late 1800’s and [AethericLtd] have refurbished an old 1930’s design and given it a bit of steampunk flair.

As is common with older mechanical devices that have been sitting for extended periods of time, the first thing this machine needed was a bath. The machine was separated into its three main parts and soaked in a degreasing solvent. The keyboard …read more http://pje.fyi/PrQSGx
