[Nicholas Rehm] works during the day at the Applied Physics Laboratory at Johns Hopkins, Maryland, so has considerable experience with a variety of UAV applications. The question arose about how the ...

Have you ever tried to balance a broomstick or dowel on the tip of your finger? It’s not so easy. Just how fast should you move your hand to keep the stick balanced? How should you respond if somebody ...

In this video I show you how an inverted pendulum works. The physics behind the gravity defying pendulums requires complex ...

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 ...

The robot above can balance an inverted pendulum. But wait, it gets better. It can balance an inverted pendulum that is articulated in the middle like the one seen above. Wait, wait, wait… it gets ...

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 ...

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 ...
