from the same company that brought you Big Dog, the robot so loud the enemy can hear you coming from miles away lol . . .

You forgot how inconvenient it is for a harness system to be set up everywhere.  Is it just me, or does it look like the human belay is helping navigate those stairs upright.  ;D

Admin:
I'm convinced it's authentic robust control.

As for the tether, it not only passes power and control, but it also has oil coolant being pumped through to cool the motors that are being over-driven. So, no battery mass, and reduced motor mass, makes it possible. I was given the impression when going to a talk at DARPA that batteries would need to improve by at least 10x in power density before they could realistically remove that tether with decent operational times.

jwatte:
The latest one uses hydraulics rather than motor actuators. With closed-loop control. And LIDAR. SWEET!

I wish I could be working with this level of hardware and software :-)

10x!   :o  How do they overcome the power problem with Big Dog?
