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
802.11B 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
