Two questions

1 IS this the only sonar From 3d robotics … 1423.l2649.

2 How can i reduce the speed from the rover, i don`t have that much room to test.
Thank you >-}}}}})*>

Hi Jrualj,
The sonar inputs to the APM are designed for sonar outputs that produce a voltage that is proportional to detected distance. If your sonar produces this kind of output it will work with the APM.

The CRUISE_THROTTLE parameter sets the initial throttle output in percent. The CRUISE_SPEED parameter in m/s defines the speed the rover will try to obtain based on the GPS speed input.
