Cornell's Franz Nigl and Jeremy Blum demonstrate their truss-climbing robot in this video, which accompanies a paper accepted into IEEE Robotics and Automation Magazine. The robot can climb and reconfigure the trusses in a 3D structure, redesigning a building on the fly, autonomously. It would be pretty cool to see a swarm of these running a genetic algorithm, dynamically redesigning a skyscraper.
This video presents a robot capable of autonomously traversing and manipulating a 3D truss structure. The robot is able to approach and traverse multiple structural joints using a combination of translational and rotational motions. A key factor in allowing reliable motion and engagements is the use of specially designed structural building blocks comprised of bidirectional geared rods. A set of traversal plans, each comprised of basic motion primitives, were analyzed for speed, robustness, and repeatability. Paths covering eight joints are demonstrated, as well as automatic element assembly and disassembly. We suggest that the robot architecture and truss module design, such as the one presented here, could open the door to robotically assembled, maintained, and reconfigured structures that would ordinarily be difficult, risky, or time consuming for humans to construct.

I first started writing about the remarkable Joi Ito in 2002, and over the decade and a half since, I’ve marvelled at his polymath abilities — running international Creative Commons, starting and investing in remarkable tech businesses, getting Timothy Leary’s ashes shot into space, backing Mondo 2000, using a sprawling Warcraft raiding guild to experiment with leadership and team structures, and now, running MIT’s storied Media Lab — and I’ve watched with excitement as he’s distilled his seemingly impossible-to-characterize approach to life in a set of 9 compact principles, which he and Jeff Howe have turned into Whiplash, a voraciously readable, extremely exciting, and eminently sensible book.
RAWIllumination.net announced yesterday that a manuscript by Robert Anton Wilson has been found and will be published by RVP Publishers in the first half of 2017. The manuscript appears to be substantial, weighing in at 340 pages. RAW and Discordianism scholar Adam Gorightly rediscovered the book and wrote a forward for it. And although the […]
“Information Doesn’t Want to Be Free” is my 2014 nonfiction book about copyright, the internet, and earning a living, and it features two smashing introductions — one by Neil Gaiman and the other by Amanda Palmer.
The Pocket Tripod PRO had massive Kickstarter success in 2013, raising almost $85,000 in a single month. But this isn’t just another case of pre-release product hype. This ingenious little device folds out from a credit-card-shaped plastic slab into a sturdy stand with a surprisingly wide range of motion. In portrait orientation, your phone slides […]
Loot Crate is a totally different kind of subscription service that mails subscribers monthly boxes filled with curated geek, pop culture, and gamer paraphernalia. Its cult following awaits a box every month filled with everything from bobble heads to T-shirts to special edition collectibles. But nothing gets Loot Crate fans as excited as the limited […]
The ARMOR-X Mini Flexible Phone Tripod is a smartphone tripod that is designed with flexible legs to rest on virtually any type of surface. Other tripods have proved useless unless I conveniently have a flat surface in front of me, which is why this particular tripod was appealing enough to try out. The ARMOR-X is compact and easy […]
