'''
This is an example builder script that sets up a rover in Morse to
be driven by ArduPilot.
The rover has the basic set of sensors that ArduPilot needs
To start the simulation use this:
morse run rover.py
Then connect with ArduPilot like this:
sim_vehicle.py --model morse --console --map
This model assumes you will setup a skid-steering rover with left throttle on
channel 1 and right throttle on channel 2, which means you need to set:
SERVO1_FUNCTION 73
SERVO3_FUNCTION 74
