Re: Debugging a Robot

You are right. You just have to call a command that executes immediately
like e.g. ahead(), turnLeft() etc. If you are only calling set methods
like setAhead(), setTurnLeft() etc., you need to call execute() in order
to execute all pending commands. :-)

using, for example, ahead instead of setAhead and turnRightRadians
instead of setTurnRightRadians.

runtime error in the javavm, but I don't know how I can see the error
output. How would I go about debugging the robot and seeing the runtime
error? I'm pretty sure the error comes from a division by zero
somewhere, but I would really like to know the line it occurs on.
