2.  Long Range Vehicle Control in collaboration with HKUST  Semi-autonomous tank  Controller – Android application  Video wirelessly transmitted from vehicle to controller  Using the Pandaboard

3.  An ability to send/receive/decode commands from a controller wirelessly  An ability to control direction/firing capability of a vehicle  An ability to autonomously avoid obstacles encountered by the tank  An ability to provide sensor feedback to a wireless controller  An ability to monitor a battery and prevent unexpected signal loss by alerting operator

4.  Power Sourcing and Distribution  Motor Driver Circuitry  Proximity Sensing Array  Serial Communication

5.  Everything powered by a 12v drill battery  Main motors run off of 10-12v  Efficient DC/DC switching regulators to drop 12v down to 5v and 3.3v  Microcontroller runs on 3.3v  Pandaboard runs on 5v  Coulomb counter used for battery monitoring

6.  L298 H-Bridge IC used for two main drive motors and turret motor  Require large heatsinks and channels must be tied due to current draw  Power MOSFET used for airsoft firing mechanism

7.  Infrared sensors distributed around the perimeter of the tank  Long Range sensors (20-150cm) used for object detection  Short Range sensors (3-40cm) used for ledge detection  Algorithm to handle object detection in software

8.  Used for all communication between the microcontroller and the Pandaboard  Commands received from controller  Status messages and sensor data sent to controller  ST3232 level translator used to interface with microcontroller UART

10.  Package – 64 pin LQFP  This package makes ports A, B, and C available  Main on-chip peripherals used are UART, PWM, ADC, and several GPIO
