Most robots depend on controlled environments, because the real world is hard to get around in. The smaller the robot, the bigger this problem because little wheels (or legs) can take only little steps. One way around that is MIT’s latest one-legged hopping robot, which sports a set of four insect-like wings on its top […]
Over on the Google blog [Joel Meares] explains how Google built the new family of Gemini Robotics models. The bi-arm ALOHA robot equipped with Gemini 2.0 software can take general instructions and then respond dynamically to its environment as it carries out its tasks. This family of robots aims to be highly dexterous, interactive, and […]
Underwater robots face many challenges, not least of which is how to move around. ZodiAq is a prototype underwater soft robot (link is to research paper) that takes an unusual approach to this problem: multiple flexible appendages. The result is a pretty unconventional-looking device that can not only get around effectively, but can do so without […]
If you want to get started in microfluidic robotics, [soiboi soft’s] salamander is probably too complex for a first project. But it is impressive, and we bet you’ll learn something about making this kind of robot in the video below. The pneumatic muscles are very impressive. They have eight possible positions using three sources of […]
[JesseDarr] recently wrote in to tell us about their dynamic Arm for Robitc Mischief (dARM), a mostly 3D printed six degrees of freedom (6DOF) robotic arm that’s designed to be stronger and more capable than what we’ve seen so far from the DIY community. The secret? Rather than using servos, dARM uses brushless DC (BLDC) […]
[Antoine Pirrone] and [Grégoire Passault] are making a DIY miniature re-imagining of Disney’s BDX droid design, and while it’s still early, there is definitely a lot of progress to see. Known as the Open Duck Mini v2 and coming in at a little over 40 cm tall, the project is expected to have a total […]
If you’re designing a robot for a specific purpose, you’re probably ordering fresh parts and going with a clean sheet design. If you’re just building for fun though, you can just go with whatever parts you have on hand. That’s how [Sorush Moradisani] approached building Esghati—a “robot made from garbage.” Remote viewing made easy. The […]
Hackers enjoy a good theme, and so it comes as no surprise that every time March 14th (Pi Day) rolls around, the tip line sees an uptick in mathematical activity. Whether it’s something they personally did or some other person’s project they want to bring to our attention, a lot of folks out there are […]
Getting a robot to stand on two wheels without tipping over involves a challenging dance with the laws of physics. Self-balancing robots are a great way to get into control systems, sensor fusion, and embedded programming. This build by [mircemk] shows how to make one with just a few common components, an Arduino, and a bit […]
The cool thing about the droids of Star Wars is that they’re not that hard to recreate in real life. R2-D2 is a popular choice, but you can even build yourself a neat little BB-8 if you’re so inclined. [Piyush] has built a particularly compelling example that’s transparent, which lets you see the internals and how it […]
