The ros controller will timeout if it doesn't receive a cmd_vel message
in a given period, stopping the wheels.
webui sends messages at 100ms intervals, so the update rate needs to be 10Hz
This may need to be reviewed when using other input systems.
Uses the mecanum controller properly across physical and virtual
There is a timing issue with i2c which is why the control update is limited to 10hz
The sonar and LED's arent yet working, this will come soon.
