If you make anything that moves, like a robot, you quickly realize that turning can be a pain. That’s why there are a number of designs for wheels that can go in different directions. One of the most common is the mechanum wheel. [Jeremy] explains how they work by filming them from below on a […]
Unfortunately, [Dave Niewinski]’s kids are still too little to go on a real roller coaster. But they’re certainly big enough to be tossed around by this giant robot arm roller coaster simulator. As to the question of why [Dave] has a Kuka KR 150 robot in his house, we prefer to leave that unasked and […]
Even if you don’t like to build replicas of movie robots, you can often draw inspiration from cinema. Everyone knows Robby the Robot, Gort, and R2D2. But [Atomic Snack Bar] treats us to some lesser-known robots from movies in the 1930s, 40s, and 50s. While we are pretty up on movies, we have to admit […]
Don’t let the name of the Open-TeleVision project fool you; it’s a framework for improving telepresence and making robotic teleoperation far more intuitive than it otherwise would be. It accomplishes this in part by taking advantage of the remarkable technology packed into modern VR headsets like the Apple Vision Pro and Meta Quest. There are […]
[Will] wanted to build some animatronic eyes that didn’t require high-precision 3D printing. He wound up with a forgiving design that uses an Arduino and six servo motors. You can see the video of the eyes moving around in the video below. The bill of materials is pretty simple and features an Arduino, a driver […]
Traditionally, sockets for prostheses are created by making a plaster cast of the limb being fitted, and are then sculpted in carbon fiber. It’s an expensive and time-consuming process, and what is supposed to be a customized socket often turns out to be an uncomfortable disappointment. Though prosthetists design these sockets specifically to take pressure […]
If that sounds like a mouthful, just call it SCUTTLE – the open-source mobile robot designed at Texas A&M University. SCUTTLE is a low cost (under $350) robot designed for teaching Aggies at the Multidisciplinary Engineering Technology (MXET) program, where it is used for in-lab lessons and semester projects for the MXET 300 – Mobile […]
Getting a legged robot to stay upright, especially a quadruped or biped, can be a challenging undertaking. To experiment with different approaches, [James Bruton] built robot dog test platform and is playing with “dynamic compliant simulated springs“, or in other words, using the motors to act as though they were springs and dampers.. When robotic […]
Bobble-Bot uses the standard inverted pendulum problem to teach modern robotic control using a Raspberry Pi, RT-Linux, and ROS. We’re really impressed by the polish and design effort put into this project, and it’s no surprise that it’s a finalist in the 2019 Hackaday Prize. Bobble-Bot is a top heavy bot sitting on two BLDC […]
[Michael Horne] recently shared his thoughts on the RedBoard+, a motor controller board for the Raspberry Pi aimed at robotic applications. His short version for busy people is: if you’re at all into robotics, get one because it’s fantastic. At heart the RedBoard+ is a motor controller, but it’s packed with I/O and features that […]
