While impressive, it just points out how much our own brains do ..this robot is running on a very simple flat course and still looks pretty clumsy. (Although better than any robot before no doubt).
It's also not having to worry about lateral stability because of the stabilizing rod. Adding that it will make things ever more complex.
Then, drag it out to some interesting, technical trail and get that to work.
They have a lot more programming to do 8)
