1. ECE 477 Digital Systems Senior Design Project  Spring 2008
Team #1 (KANG) – Sentinel Mark I
The Sentinel Mark I is an automated, robotic sentry turret capable of autonomous and user-controlled defense of an area. It is designed to perform the same duties as a human soldier on sentry duty. Features include a mounted automatic weapon, user override commands, an easy-to-use graphical user interface, remote shutoff for friendly personnel and a hinged panel to allow for easy repair and replacement of internal circuitry. This is intended for military and law enforcement applications, although it may also be used by shooting sport enthusiasts, provided they use a non-lethal weapon mounted on the turret.
PROJECT SPECIFIC SUCCESS CRITERIA
1. An ability to electronically fire an airsoft pistol (either autonomously or manually).
2. An ability to detect off-camera motion via ancillary sensors.
3. An ability to remotely disable device to prevent “friendly fire.”
4. An ability to automatically detect a (hostile) target within the camera’s field of vision.
5. An ability to pan and tilt the firearm assembly (a minimum of) 45° in the longitudinal direction and 30° in the latitudinal direction.
