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

  2. 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.

  3. 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.

  4. Hardware Implementation: Base Station Computer Base Station 68HC11 SerialRS-232 802.11b RF Transmitter/Receiver Rover

  5. Hardware Implementation: Red Rover 2 Stepper Motors Temperature Sensor Sonar Transducer LCD Screen Camera Light Sensor Red Rover 68HC11 Serial RS-232 GPS Sensor Flash Card 802.11b RF Transmitter/Receiver

  6. Processor • Motorola 68HC11 micro-controller • Internal SDI Serial Interfaces • Parallel Interface • Several I/O Bus-lines

  7. Possible Parts Long Range 433MHz Serial RF Modem w/ Antenna and Interface Cable One Wire Digital Temperature Sensor

  8. Possible Parts(cont.) GPS RS232 Dual Port Carrier Board - Lassen IQ Ultrasonic 25kHz Transducers

  9. Software Implementation • User interface will be implemented in C/C++. • Drivers and ISR for all the motors, sensors, and communication peripherals will be implemented in a combination of assembly and/or C/C++.

  10. Division of Labor • Crossen – car processor, RF, Motors, User Interface • Peter – car processor, RF, Video, User Interface • Nancy – base station processor, Temp sensor, GPS, User Manual • Eric – base station processor, light sensor, Motors, Data Processing

  11. Schedule

  12. 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.

  13. 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

  14. Questions? • Thank You!
