Robotic technologies give the opportunity to put in practice various mathmatical, scientific, technical and computer science based concepts while tackling effectively various engineering concepts (building mechanics, and setting up gears, mounting wheels on axles, connecting them to a motors, use of sensor, etc.). Various robot kits are available on the market (like LEGO MINDSTORMS NXT).
More information on LEGO MINDSTORMS NXT, can be found here.
The use of robots in an educational setting offers students multiple modes of learning. Not all students easily retain information from the oral lecture style used in the traditional classroom. Some students may be kinaesthetic learners and learn best by doing while visual learners need to see a diagram or chart in order to fully understand. For example, in the neuroscience classroom, classic conditioning might be explained through an oral discussion, a diagram on an overhead projection and then physically demonstrated with a robot.
