Introduction and Purpose Watch Your Back! is a wirelessly controlled amphibious vehicle armed with a camera with abilities to perform a wide variety of human tasks –Ability to transport items from one room to another –Can be used to enter hazardous situations, analyze the situation and risks, and perform necessary actions –Eliminates threats to human lives in a battlefield when equipped with a gun –Home/Business Security –Recreational

Objectives Eliminate threats to human life –Will equip the amphibious vehicle with a paintball gun and camera – Will be able to control from a remote location Have ability to maneuver and fire from remote location –View all data and react in real time

Description Wireless amphibious vehicle equipped with a camera and paintball gun Sensors may include: motion, video, audio and light Vehicle can be controlled by B communication The data will be transferred back wirelessly to a computer with a controller (keyboard or PS2 controller) Data can be viewed and controlled in real time by a user interface
