Researchers have demonstrated a way to maintain an unstable quantum system by applying bursts of microwave radiation. The technique is comparable to methods used for controlling an inverted pendulum ...

This project features a simple two-wheel robot that has the ability to balance itself when it’s going to fall. The robot possesses a switch as a sensor that starts the motor and moves the robot to the ...

Newton’s Cradle is thought of as the most elegant of executive desk toys. But that 20th-century dinosaur just got run off the road as [Ben Katz]’s Furuta pendulum streaks past in the fast lane, ...

Apparently, balancing a pole on top of a flying quadrocopter robot wasn't challenging enough for the researchers at ETH Zurich's Institute for Dynamic Systems and Control. Their latest project has two ...

The purpose of this application note is to describe how a PIC16F684 can be used to implement a positional Proportional-Integral-Derivative (PID) feedback control in an inherently unstable system. An ...

For [Gunnar]’s diploma thesis, he wanted to build an autonomous bicycle. There’s an obvious problem with this idea, though: how, exactly does a robotic bicycle stand upright? His solution to balancing ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. Arthur J. Weed was a skilled mechanic ...
