Very Impressive, but Totally Fake! Even if you don't believe that it's CG, consider the drive mechanics claim. It states that everything is 95% mechanical drive, 5% electrical.
Think about what it would take with "Cable Drives" (whatever THAT is) to achieve that level of mobility for a mass that big.
A HUGE giveaway - LISTEN to the audio - you hear the sound of ELECTRICAL SERVOS as the robot moves, yet he claims only 5% electrical locomotion!
"The lessons I learned working with the cable drives on the forearm allowed me to make some refinements to the leg design before the parts were sent out to be machined which probably saved me a few weeks time."
"I used machined drive shafts to transmit power to the legs and also used purpose built gearboxes..."
"At first I entertained the thought that the robot may be powered primarily by an electrical source. But I avoided all of this when I took the leap to a more mechanical system. You just can't beat the power density of petrol, and even with the abysmal conversion efficiency of all IC engines, they still beat batteries."
"For a walking gait, about 95% of the power comes directly from the 1.6x4, with the rest electrically coupled. "
