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.

Vlad Taltos is the (anti)hero of Steven Brust's stupendous, longrunning fantasy series (which is nearly complete, a generation after it was begun!); Issue 220 of Dragon magazine (August 1995) included a feature by Ed Stark explaining how to play the human assassin and witch who lives amidst a race of nearly immortal elves, against whom […]
The inaugural Heavy Metal Knitting World Championship were an unqualified success, with competitors from the US, Russia, Japan and beyond converging on Joensuu, Finland to thrash and knit: competitors such as Woolfumes, Bunny Bandit and 9" Needles thrashed to heavy metal music while knitting, for an audience of about 200. The winners were the five-person […]
When it comes to passwords, there’s no such thing as paranoia. You want them secure and complex, and you definitely don’t want to repeat them on all your accounts. The trouble is, the internet seems to keep growing. And so do those accounts. Just one lockout from an important email or banking site is enough […]
With the rising temperatures on tap this summer, the climate is going to be a frequent topic of conversation, and those conversations won’t be happy ones. Luckily, there’s a way to do a little climate change of your own – in a safe and sustainable way. When it comes to personal air conditioners, EvaPolar is […]
Whether you’re using them for next-level selfies or steady tracking shots, gimbals are a must for anyone who wants to maximize the potential of these powerful smartphone cameras we’re all carrying around. But those smartphones are also supposed to be portable, and let’s face it: Gimbals tend to offset that advantage. Weighing in at just […]
