That thing is just creepy... 
There are two types of people in this world: those that pronounce GIF with a soft G, and those who do not deserve to speak words, ever.

They should program it to shovel snow, mow the lawn, and wash the car, you know, useful stuff.

I we don't hear from you again, we'll know why!

very impressive but I can't help feeling we'd be a lot further on if a little less effort was wasted on human-like characteristics (bipedal walking is a really stupid way of getting around, let's face it). All that work on recovering from stumbles that it really doesn't need to make could surely have been better spent?
I am not a number. I am a ... no, wait!

I dunno about bi pedal, maybe 3 or 4 leg would be a good idea... although bi pedal use less space, smaller surface on the ground so it's not a complete waste..
But recovering from stumble is essential! What's the point of a robot which can't do anything because it can't reach its destination and break fragile stuff as it falls (all the time)?!

Recovering from a stumble is only essential if you have a robot that stumbles - which all bipedal robots do (see some of the hilarious footage from robot trials around the world!) My point was that the effort should be going into finding inherently stable configurations which don't stumble rather than slavishly adhering to the bipedal method just because it looks more human. This needn't take up much more space especially if the centre of gravity can be kept low.

I would guess the problem is the battery use. Because bipedals need several times less energy on the same distance than 4-legged creatures. At least, that's what I read about why humans are bipedals.

The study which suggested this compared only humans and chimps. It confirms that human beings walking on two legs are more energy efficient than chimps walking on four and also, for the most part and to a lesser degree, than chimps walking on two. But as chimps are already halfway between quadriped and biped, with their arms significantly far along the track towards becoming useless as legs, all the study really tells us is that humans are better at being humans than primates at a stage of evolution a few steps behind humans which .. you know ... duh!
There are so many disadvantages to bipedal walking in terms of wear on joints, the need for additional supporting framework such as ligaments and tendons, pressure on the feet, balance and stability issues caused by raising the centre of gravity, and a dozen other consequences from having our vertebra in a shaky column rather than a nice self-supporting, suspended arch, that it's not easy to believe that a little energy efficiency gain is sufficient evolutionary advantage to explain it entirely if at all.

They actually tried a 4-legged robot but found it to be too noisy. They decided to go with only two legs, then, because it would be less conspicuous distracting.
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)

and besides, it is more difficult to make a four legged version walk round as if it were terminally constipated.
It goes without saying

A major reason to make it bipedal is because much of our surrounding is foundationally geared towards human habitation. If all we're going to do is make these things walk about in open space then I see your point. Ultimately the goal is to have these things be among people without having to make special provision for them (think stairs, aisles, doors etc.)
