Is that the area where there are invisible walls that you need to navigate
around? There are two ways to complete it:

1) The way the designers intended: In the NE of the level is a maze area that
is an exact image of the minefield. You can use that as a guide to program
a robot to navigate the maze using a simple state machine with inputs from
the bumpers, and outputs to the thrusters... ie. go east: east bumper hits
then change to moving north, etc.

2) A cheater way. Using the NE maze as a guide, get inside the robot, and it
will still be able to enter the minefield with you in it. A robot needs to
thrust against a wall for about a second before it 'explodes'. So hard-wire
a thruster with a NOT gate to go east, and whilst watching through the eye,
stay in the Remote Control icon, and turn off power immediately when you bump
the wall, then simply rewire to the thruster for the direction you wish to
go next, turn on the power again, and repeat.
