The magic will worky only if velocity > 0

There are several levels :

On the arduino nano, i have strange behavior with setVelocity.

I have a big difference between setVelocity(50) and setVelocity(-1)

setVelocity(50) is very slowly.

Is it normal ? 

Is this correct with old speed function ?

The day when we can ask our robot to get us a beer and it walks to the fridge get the beer out and returns it to us out in the shed will be truly a great day.  There are some who say it can't be done, and those people will never achieve this ultimate goal, but as a community this goal is achievable and quite possibly before the end of next year.

I am trying to get the UltrasonicSensor working via MRL and keep getting a Null Exception when adding the RangeListener.  I've copied the various versions of code that I've seen.  Anyone has complete code that works?
