Two Cars Roundabout
Problem Statement:
The pre-placed blocks drive the two linkbots to the entrances and attempt at the turn. Modify the existing blocks and add in new ones to navigate the two linkbots around the roundabout to reach their destinations (Robot1 goes from red to green entrance. Robot2 goes from orange to blue.)
