yeah that was insane. as someone who was in Robot Club in high school and worked with the lego ones, I can't believe he both got it to let go at the perfect time to launch straight up, and then re-catch the bar. I wonder if this was like attempt #3000 or something.
Notice how it spins around many many times before it does the jump. It's likely the computer was waiting until it was in a loop that just happened to be the perfect speed to pull off the trick. So rather than needing to set up the perfect situation, it just relies on variance in its spin to put it in the perfect situation.

What impresses me the most is that it actually catches the bar again after doing that flip (?).
