7701 below is correct. I was the ref. It took a while, but we did get it correct. The issue was the the robot only touched another robot that was partially outside of the protected area and moved it further into the starting tile into contact with a cube.
If the robot had push a cube into the starting tile of the opponent, that would have been different. I am embarrassed that it took a long discussion to get it right, but I am happy that we took the time to do so.
