Reaction wheels are useful things, typically used by satellites to keep themselves oriented the right way up in space. Turning the reaction wheel creates an equal and opposite torque in …read more Continue reading Building Reaction Wheels With Python and LEGO
[Nicholas Rehm] works during the day at the Applied Physics Laboratory at John Hopkins, Maryland, so has considerable experience with a variety of UAV applications. The question arose about how …read more Continue reading Inverted Pendulum Balanced On A Drone
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 …read more

Robots that can jump have been seen before, but a robot that jumps all the time is a little different. Salto-1P is a one-legged jumping robot at UC Berkeley, and back in 2017 it demonstrated the ability to hop continuously with enough control to keep itself balanced. Since then it has been taught some new tricks; having moved beyond basic stability it can now jump around and upon things with an impressive degree of control.
Key to doing this is the ability to plant its single foot exactly where it wants, which allows for more complex behaviors such as hopping …read more
