Self-Balancing Robot


(YouTube Link)


The Balancing Cube is a robot that can remain balanced on any one of its corners, even when pushed. Six motorized weights quickly move to keep the robot's weight balanced whenever it is in danger of falling over:

The Balancing Cube is an example of a distributed control platform. Each module....is a self-contained unit with a computer, battery, motor, and inertial sensors (a tri-axis accelerometer and tri-axis rate gyro). So instead of relying on a centralized controller, the modules share their inertial data through a bus network. Then each module combines its own data with the shared data to determine the orientation of the cube -- and command its motor accordingly.

I have a lot of useless information crammed into my brain. There are times when I know a lot of the answers. I feel especially good when I know the final one and all 3 contestants do not. The reality is that if I was keeping count, I probably know less than 50% of the answers. If I ever tried and got on the show it would be my luck that categories like 13th Century Bulgarian Poetry would be on the board. I still watch a lot, especially when someone is on with 5 or more wins.

The earlier format, where the players could buzz in early, is quite a downer for me, the viewer. I haven't even fully understood the question yet. I wonder if they are more predicting that they might know the answer by the time the question finishes, than actually knowing the answer.
