Robot Graffiti

There’s talk of robots and AIs taking on jobs in many different industries. Depending on how much stock you place in that, it might still be fair to say the more creative fields will remain firmly in the hands of humans, right?

Well, we may have some bad news for you. Robots are now painting our murals.

Estonian inventor [Mihkel Joala] — also working at SprayPainter — successfully tested his prototype by painting a 30m tall mural on a smokestack in Tartu, Estonia. The creative procedure for this mural is a little odd if you are used to the ordinary …read more http://pje.fyi/PnK1jV

GuitarBot Brings Together Art and Engineering

Not only does the GuitarBot project show off some great design, but the care given to the documentation and directions is wonderful to see. The GuitarBot is an initiative by three University of Delaware professors, [Dustyn Roberts], [Troy Richards], and [Ashley Pigford] to introduce their students to ‘Artgineering’, a beautiful portmanteau of ‘art’ and ‘engineering’.

The GuitarBot It is designed and documented in a way that the three major elements are compartmentalized: the strummer, the brains, and the chord mechanism are all independent modules wrapped up in a single device. Anyone is, of course, free to build the whole thing, …read more http://pje.fyi/PgJ76c

Simple Step-Climbing Robot Climbs Like It’s On Mars

[Navin Khambhala] is a master at making simple what most would expect to be a complex build. Now he’s done it again with a remote controlled robot that can easily climb steps and role over rough terrain. The parts count is small and many of them are commonly available.

The suspension that makes it all possible is the rocker-bogie. It’s the same suspension we’ve all seen used by the various rovers ambling around on Mars. The whole frame is made of PVC pipes with some connecting metal bars, and each wheel has its own twelve-volt DC motor. Motor control is …read more http://pje.fyi/PflTtV

The Hackaday Prize: Exoskeletons for the Masses

While medical facilities continue to improve worldwide, access to expensive treatments still eludes a vast amount of people. Especially when it comes to prosthetics, a lot of people won’t be able to afford something so personalized even though the need for assistive devices is extremely high. With that in mind, [Guillermo Herrera-Arcos] started working on ALICE, a robotic exoskeleton that is low-cost, easy to build, and as an added bonus, 100% Open Source.

ALICE’s creators envision that the exoskeleton will have applications in rehabilitation, human augmentation, and even gaming. Also, since it’s Open Source, it could also be used as …read more http://pje.fyi/Pf0XST

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 http://pje.fyi/PbRfp8

Monster Mindstorms Delta Bot Delicately Picks Candy

A group of embedded developers from Sioux Embedded Systems in Eindhoven, the Netherlands, wanted to get experience working on Microsoft .Net. To make it fun they made it their project to produce a LEGO train with visitors at LEGO World, the official LEGO convention in Denmark. The team developed an application in C# to fully automate the train, with Mindstorms NXT and EV3 bricks as well as LEGO Power Functions motors controlling everything.

The train project carries a simple premise: the visitor chooses one of four colors, and the train goes and picks up a piece of simulated candy with …read more http://pje.fyi/PZ1jl0

This Isn’t The R2-D2 Controller You’re Looking For

Who loves a good R2-D2 robot? Everyone, but especially young Star Wars fans who — frustratingly — have no problem spotting a controller and spoiling the illusion of an R2 unit brought to life. [Bithead942]’s concealed his R2-D2’s remote and re-establishes the illusion of an autonomous droid — no Jedi mind-tricks necessary.

[Bithead942] prefers to accompany his droid in traditional a Rebel Alliance pilot’s suit, so that gives him a bit of extra space under the jumpsuit to help conceal the controller. Dismantling a Frsky Taranis X9D controller, [Bithead942] meditated on how to use it while so concealed. In a …read more http://pje.fyi/PX6VzT
