 The Barkmaster2000 (BM2000) is intended to sense sound, turn a motorized vehicle in response to that sound, and drive towards the source of the sound. The idea is that Bryan’s dog likes to chase remote control cars, but hasn’t experienced the pleasure of a remote control car that automatically chases her.  When she comes across a remote control car, she will usually bark like she has lost her mind.  The BM2000 responds to her barking by taking action that will increase the amount of barking.   The integrated system of the BM2000 and Bryan’s dog creates a barking frenzy that the world has never seen before.  Here is a picture of Bryan’s dog.  Her name is Sake.
 The BM2000 uses independent PWM motor drives, MEMs sensing for audio, and IR sensing for doggie location.  The MEMs sensors and IR sensor are modular PCBs that externally interface with the SJSU development board to create the integrated BM2000.

 == Software Design ==
 The software architecture is the equivalent of a state machine, where states are either represented as while loops or functions that are implemented once prior to jumping to the next state (see Figure below for the software state diagram).

 The project was a successful endeavor for the Barkmaster team.  Our approach was to make an obtainable goal that required us to learn how to program the LPC1758 while incorporating new hardware functions that neither Patrick nor Bryan had used before.  The code was intentionally kept as simple as possible to reach our obtainable goal.  The audio sensing was definitely the most challenging of all the interfaces, requiring the most debugging time in both hardware and software.  Overall, both members of the team enjoyed the project and the class.  We have further plans to continue using the SJSU development board for fun projects that increase our engineering knowledge.
 The final product is shown below.  The handsome carrying tote can be purchased with the Barkmaster2000 for an additional $56,000.

 Figure XX shows the setup used to test out the Ultrasonic Distance Sensor Interface. Measurements were taken to verify that the sensor accuracy was sufficient. For our application accuracy on the order of +/-6.0 inches was sufficient since we are using the sensor to prevent the robot from running into our four legged friend. The sensor operation is fairly simple. A 10 usec positive going TTL pulse is sent to the Trigger Input. This commands the sensor to begin sampling the sensor and generate a pulse on the Echo pin that is also a positive going TTL pulse. The pulse width of the Echo pulse is a function of the distance of the detected object. The software driver will measure the pulse width on a GPIO input and calculate the distance using the distance equation stated above in the Sensor Pin Names and Descriptions section.

 Figure XX shows the top side of the Ultrasonic Sensor Board. This sensor was difficult to mount as is, so it was installed on a perf board that mounts to the bottom side of the lower level section of the BM2000. Also installed on the perf board are supporting electronics and a ribbon cable that is routed to the top level of the BM2000. On the top level the ribbon cable connects to the BM2000 Mux Board. None of the ultrasonic sensor signals are multiplexed. This board was used as a signal distribution point since it is in close proximity to the SJSU LPC1758 Development Board. Since the ultrasonic sensor requires 5V(TTL) logic signals, a logic level converter was used to interface the Trigger and Echo signals with our SJSU LPC1758 Development Board.
