DBC File
In our DBC file, we have 6 nodes, DRIVER, SENSOR, BRIDGE, GEO_CONTROLLER, COMPASS, and MOTOR. Each of them represents a message sends from one node to another via the CAN bus.
1. The DRIVER sends the throttle and wheel angle command to the MOTOR so it knows when to speed up, speed down and turn. 2. The SENSOR sends the information about how far away is each of the Ultrasonic sensors away from the obstacles

/*** TEMPORARY NOTES ***/
1. Encountered issues with getting fixed coordinates. Fixed it by obtaining external antenna and plugging in CR1220 as a backup battery.
2. The dbc format can support up to only 6 decimal point, which is not accurate when it is being used to store the GPS coordinates. Fix by using the Degrees Minutes Seconds format.
