Power Supply Design
nRover needs two different power supplies: one is used to power up pcDuino, which needs 5V/2A. The other is used to power up motor shield. The typical voltage for motor shield is 12V. So we use a 12V/4800mA Li-ion battery. MIC29302 linear regulator is used to bring 12V down to 5V used for pcDuino.

Software Part:
pcDuino implements the following components:
1.Control motors through motor shield.
2.A command server that listens to a socket and accepts commands from client.
3.A video server: mjpg_streamer.
Software on pcDuino:
1. Robot control program (car_test.c)
1.Copy car_test.c to c_ environment\sample. Edit makefile under sample, and insert car_test under OBJS=. Save and compile. An executable named car_test is complied under output.
2.Video stream details can be referred to in http://www.pcduino.com/?p=808.
