Do you realize how many people are not going to sleep tonight?

Here's my guess on how it works...
Could it work this way? Polycarbonate is up with a cable or cables attached about 3 inches from the end. Drive under, pull up to pyramid cable towards pyramid. Start pulling the cable down and the polycarbonate goes on the other side of the bar. An angle is formed between the polycarbonate and the cable where the horizontal bar on the pyramid rests. As you wind up the bot is lifted. Get to a point where you rotate out or over the bar, two hooks that you hang from (or the bot goes up and over and hangs from). Release poly carbonate, then pull yourself up to the next level.
We'll know for sure if they post a video.
