🦾 3D printing approach strings together dynamic objects to assemble bionic robots, sculptures and more

techxplore.com/news/2025-03-3d

techxplore.com3D printing approach strings together dynamic objects to assemble bionic robots, sculptures and moreIt's difficult to build devices that replicate the fluid, precise motion of humans, but that might change if we could pull a few (literal) strings. At least, that's the idea behind "cable-driven" mechanisms in which running a string through an object generates streamlined movement across an object's different parts. Take a robotic finger, for example: You could embed a cable through the palm to the fingertip of this object and then pull it to create a curling motion.

Hey! Are you a student who wants to use #bevy to do #robotics in #rust?

We've just got a job posting for two remote summer internships through the Google Summer of Code! Check it out at discourse.ros.org/t/osrf-googl, or hunt down `grey` on the Bevy Discord to ask questions directly :)

Looks super cool!

ROS Discourse · OSRF Google Summer of Code 2025 🌞OSRF Google Summer of Code 2025 🌞 Hi Everyone, I am excited to announce that all of our Google Summer of Code (GSoC) projects for 2025 are now available online in our GSoC Wiki. If you are unfamiliar with GSoC, it is a summer internship program sponsored by Google that is open to undergraduate and graduate students in most countries (see video below). The GSoC program allows students to work with veteran open source developers over the summer to contribute to open source projec...

Rodney Brooks on the problem(s) with humanoid robots. So yeah sure Tesla is going to solve this, in a year? OR then deliver robots that you need to stay very well clear of when they are walking around…

You look at this Boston Dynamics video differently after reading the quote.
While impressive, Atlas is still essentially bruteforcing bipedal walking.

Like all modern humanoid robots Cardea did not walk in a way that used passive dynamics to store energy, and basically modulate the behavior of a passive mechanism that had only low energy input, which is how all animals walk. So, like all modern mobile humanoid robots (and legged robots in general) when things were going awry its control algorithms tried to recover by pumping in large amounts of energy very quickly and sometimes that didn’t quite work and the energy needed to go somewhere. Cardea could be a little dangerous in those circumstances, if it fell on you having just increased its kinetic energy. Even the spring based deployment system for its stick-like legs that were engaged when it realized it was going to fall could be dangerous. This is still a problem with all modern humanoid robots. That is why the tele-operated humanoids that were in the Tesla movie lot theater show a couple of months ago operated in two modes. When they all walked out the human guests were kept away from them. Once they stopped walking and were operating in a very different mode people were allowed to approach them, and then get fooled into thinking they were talking to an AI powered robot when they were really talking to a remote human operator. But the robot was no longer moving its feet, and no longer a source of physical danger as a result.
