TEAM 2 Remote Control Car
Team #2: Total Resources • 500 Man hours • $500 or key part availability for material and prototyping • LPI-Sean (BSEE) • LSD-Russ (BSEE) • LPM-Adam (BSEE) • LRM-Brad (BSEE) • LMM-Barry (BSEE)
Team #2 Project • Our project is a remote control car, that can display battery life speed and direction, and can turn on the lights at the flip of a switch or if it gets dark. • The benefit to the user would be a better remote control car • There are similar types of products, however we are the only one that has all of these features. • Our product would fall under the consumer industry • Picture from http://www.rccaraction.com/
Project Features • The remote control car has a two-way antenna that can transmit to and receive data from the car. • Control of the car will come from the controller. • The car can turn its lights on and off manually, and automatically if it gets dark enough. • The display will tell us the speed and direction of the car, and the battery life remaining.
