Mars Rover TEAM CPNE Crossen Davis Peter Ramer Nancy Robinson Eric Rodriguez

Description Wireless vehicle equipped with various sensors. Sensors may include: temperature, SONAR, GPS, video, light, audio, etc. Vehicle can be controlled by serial, RF, and/or B communication. The data will be transferred back wirelessly to a base station connected to a computer. Data can be viewed in Real Time by a user interface.

Description(cont.) An RC or other type of chassis will be used. We will control 2 stepper motors. Data can also be stored on a flash card in the car, time permitting.

Schedule

Risks and Contingency Plan Most of these peripherals are unfamiliar. However, our design involves many sensors,each of which are small components in the overall project. If needed, some of these can be dropped from the project while still completing our main goals.

Bandwidth We will have to figure out how to transmit all of the data we receive from our sensors back to our base station. The camera especially needs a lot of bandwidth
