There's not much of a moment of suspension, but there is some. There's a little more than with Research ASIMO.
Most legged running researchers are trying to maintain some stability criterion, and avoid spending much time in suspension, with all legs off the ground. This may be the wrong approach.
There are two schools of thought in this field. There are the people who start with walking and try to work up to running, and the people who start with hopping and try to work down to running. Most work is from the first school, but BigDog comes from the hopping faction.
Suspension is sometimes a good way to get out of trouble. You get to move all the limbs while in flight and get completely new footholds. Watch some basketball and you'll see this frequently. There's also a half-suspension in quadrupeds, as when you see a horse kick up their hind end to reposition the legs.
The technology in this area can get much, much better. The hardware, in robots, sensors, and computers, is almost good enough. Now we need smarter control algorithms.
Re: (Score:2, Interesting)
I really don't think the hardware is good enough yet. To run smoothly and efficiently robots will need joint motors that are springy and compliant just like human muscles. All of the robot limbs I've ever seen are far too stiff (with the possible exception of BigDog's legs). Just look at this guy's head and arms shake while he's running; there are huge shock forces being transmitted from the feet directly up to the torso through all those stiff joints. Not only is that likely bad for the robot, it means
Spring-like leg actuators (Score:5, Informative)
To run smoothly and efficiently robots will need joint motors that are springy and compliant just like human muscles.
I tend to agree. What you want to emulate a muscle is a spring with a variable spring constant and zero position. There are several ways to do that. A double-ended pneumatic cylinder can do it; if you pressurize both ends at a high pressure, it's stiff, and if you pressurize both ends at low pressure, it's springy. Relative differences in pressure change the zero position. If the valves are close to the cylinder, position control of pneumatic cylinders works. Someone at CWRU built a robot this way. Of course, you need an onboard air compressor.
There's a new variation on this concept - a device which is both a pneumatic cylinder and a linear motor. A pneumatic cylinder is a piston in a tube, and a linear motor is a magnet in a tube with coils outside the tube. So a device can be built which has a magnet as the piston and coils outside the tube, allowing both pneumatic and electrical operation. The linear motor does the fine positioning and the pneumatic system provides high power when needed.
It's possible to do an adjustable spring mechanically, using two actuators pulling on opposed springs. That's been tried, but most of the designs involve pulleys and strings, which tend to be troublesome. I've been working on a new string-less mechanical design in that area, one that can fit inside the space required for an R/C servo of the type used on hobbyist robots.
BigDog is hydraulic, and its actuators are very stiff. They had to put a bicycle shock absorber at the end of each leg to handle the landing shocks. But BigDog doesn't recover significant running energy. The Legged Squad Support System, the militarized successor to BigDog, may have energy recovery. There are things one can do with hydraulic accumulators and extra valves to get spring-like behavior out of hydraulics. Still, BigDog does a nice job; energy recovery will improve gas mileage, not stability.
There's also a way to fake spring-like behavior, using a "series elastic actuator". This is a leadscrew-type linear actuator in series with a stiff spring. When the spring is compressed, the drive motor frantically tries to release the pressure before the spring bottoms out. This doesn't really store much energy, but it can be used to fake something that does. Pratt at MIT came up with this, and it's a useful research tool.
There have been a number of other, more exotic muscle-line actuators, including fluids that change properties in an electric field, but so far, they're all worse than the ones mentioned above.

I don't think that's a valid analogy, but let's ignore that.
The fact that it can balance on two legs and withstand pushes is already remarkable. Self balancing is a huge step towards faster methods of locomotion.
Based on how it runs, pushing off the balls of its feet, swinging its body with its arms as counterbalance on the opposite side, it seems to have a remarkably human stride. Discounting the overly bent knees.
Also, I would be amazed if Japanese people haven't taken into account martial arts. They've probably spent months, if not years, with motion capture tech on various humans running to get this far.
I agree that it looks much better than previous attempts.
