Students learn the importance of the Pythagorean theorem as applied in radar imaging. They use a sensor unit with IRED (infrared emitting diode) to measure triangle distances and the Pythagorean theorem to calculate and verify distances....

A page which describes thermal imaging and cameras which utilize infrared radiation. The means by which these imaging devices operate is described.

Two robots can be seen playing a game of robot soccer in an enclosed field. The wheeled robots move around the area using various sensors and algorithms to help perform better than the opponent. Touch sensors are used to avoid the walls...
