This fun, easy-to-build kit features a simple 2-motor system that enables the mouse to scurry along a wall in a zig-zag manner.When motor B is on and motor A is off, the mouse steers left towards the wall. When the sensor rod comes into contact with the wall, it activates a micro switch that turns motor A on and motor B off, causing the mouse to steer away from the wall. When the mouse steers away from the wall, the sensor rod loses contact with the wall. This turns the micro switch off and turns motor A off and motor B back on again. Clear plastic design enables students to view the mouse’s inner mechanisms.

Note: Requires 1 C battery - not included.
