Scholarship Roomba Create Idea: Mouse Trap
My idea is for the robot to be a mouse hunter. I know this sounds far fetched, but all you have to do is load it with peanut butter. To describe the trap: You attach a capacitor, and leave the circuit open. The robot remains unmoving, and waits for the mouse to go for the peanut butter. When the mouse steps on the two separated plates, attached to the Create, the mouse closes the circuit, releasing the charge in the capacitor, killing it instantly.
(A disposable camera works great for this, it has capacitor and voltage needed to kill a mouse.)
The Create would search for either movement via IR, or, if possible, UV reflections from the ground. Mice leave trails of urine that reflect UV light. These trails give the Create an excellent place to set the trap. Once the charge of the capacitor is released, the Create will sound an alarm and flash an LED. Perhaps scooping the mouse into it's undercarriage and moving on to find another ideal trap site.
