the grabber goes down a bit now after moving up - this helped preventing
the motor from performing movement all the time
small changes in Initializer
the ConnectionManager sends the robot's current drive translation when
initialised (before sending pose)
test code only - can be removed again later
added a buffer for the robot size (you do not walk along walls as close
as possible either)
the robot stops 5cm more before ball or target (because the sensor is
not the robot's middle point)
target changed for current test location
