Hello all,
I am attempting to my first mobile lego robot using the lego SDK 2.0
software. Im running into problems using the touch sensor to detect a lack
of ground ahead of the robot. Im simply using two lever arms that "fall"
into the touch sensor when there is no ground infront of the robot, but
these lever arms aren't setting off my sensors, as they are too light. So I
was wondering if there is a way to program them to be more sensitive, or if
I need to redesign my levers? Thanks for the help in advance :*)
