Switch driving mode

There are 2 driving modes to control the car: manual mode and software (AI) mode. In manual mode you use the RF controller to steer the car. In software mode, the AI module in the car driver component will take over control of the wheels.

By default, the driving mode will be set to manual driving. To switch to software mode, execute the command below:

rostopic pub /master/ai/start_driving std_msgs/Bool True --once

Likewise, to stop the AI steering (software driving mode), execute the command below:

rostopic pub /master/ai/start_driving std_msgs/Bool False --once
