Project Overview MAVerick (Motorized Assault Vehicle) is a mobile gun platform controlled by a cellular phone that has the ability to establish full-duplex communication with a command center in order to transmit control and status signals. It will contain a paintball gun attached to the platform which will fire at moving targets and have the ability to detect obstacles.

Project-Specific Success Criteria ability to detect moving targets using an ultrasonic/IR sensor ability to identify and detect obstacles ability to encode and send control signals through a cellular phone to control the tank/gun ability to receive and decode control signals from the cellular ability to send status information from the tank to the controlling device

Packaging Design The MAVerick will be packaged in the above pictured tank. The turret will be removed and replaced by a paintball gun. The circuit board and all wires will be housed inside of the tank. All sensors will be mounted on the outside of the tank as seen in the next figure.

Length of Tank = 27” Width of Tank= 12” Length of Paintball Gun = 19” The numbers on the drawing correspond to the components in the parts list. Figure 1: Overhead view of tank concept drawing.

Width of base = 6” Length of base = 6” Height of base = 2”
