Absolutely incredible. It's amazing how fluid and natural his gate is when he transitions from slow to fast walking. Very impressive.

I knew from the very start. The "reveal" didn't surprise me one bit. It would have surprised me if it hadn't happened.

Congratulations?

Good TED lecture about these bionic limbs. At the end there is woman who dances on one of them.

From my perspective, I noticed his gate was odd but it was subtle enough that I put it down to him being slightly awkward or eager or something.

Or like having a stiff hip; not two prothesis. I wonder how long the battery pack for the actuators lasts? And I wonder if they have a regenerative cycle to charge the batteries and recover some of the energy from the motions each step?

Huh. How does this work? I mean, this is a pretty elementary question, but it seems it's a pimped-up peg leg - the only actuator is at the ankle, right? So no muscle or motor to bend or extend the knee joint? Which would explain the slightly odd gait - he'd have to throw his foot ahead a bit to get his leg to straighten out.

edit: I'm an idiot. It's a below-the-knee amputation.

I noticed the same at the 00:00:06 mark but since the title said there would be a big reveal I figured it could only be double bionic legs.
