If only one day the weight limit and price cap would be eliminated... we could do something like this...

To cut the chase, the best video they have:

I'm immensely impressed with these videos... almost makes me want to go and get an engineering degree. :p

It was a hoax, anyway. The videos were computer generated. You don't even need a degree in computer animation to be able to make that kind of stuff. :p

It looks very real. It's only because I don't think this type of electro-mechanical ability exists that I think the video is a hoax.

If you didn't notice the absurd explanations or sketches, the video that really gives it away is the car stopping one. A multi ton 10 foot tall hunk of metal would not move like that. Big things look slow.

Yeah, I just checked the single video he suggested.

Notice how I said that I really enjoyed the VIDEOs... it's not real... I don't think.

However, for anyone who has seen any industrial robots, things that are this large are indeed capable of moving this fast and fluid in real life. Minus catching the car... I don't think many of these are particularly far fetched. I don't think this is nearly far out there as people make it seem.

The sketches that he's using and the related formula are actually quite accurate. He's sketched out jacobian matricies for link acceleration and velocities. They certainly aren't random forumulae, on the contrary, they're exactly what you'd use for this sort of problem.

Reviewing the whole site outside of the video, including the interview, make it seem much more pluasable than a video would make it seem.

Just some food for thought. And... I see it's already been posted by Brandon on CD before. My bad!

I know there are industrial robots of this size, but im almost defenitley sure that they dont walk on two legs if at all.


Several things that put doubt in my mind right away:

That junk about overengineering Mini's for use in robots, completely not true, obviously.

Random Spinning wheel and tire on the robots shoulders.

Sketches for the head conveniently have parts to make a face.

HUD looks way to nice looking to be real. For something not even near production, they surely would not spend so much effort on a nice pretty GUI counterpart to what the robot is actually doing.

White background for the arm test, though im not exactly sure how, yet, im sure its making the video editing easier. (you'd think as long as its rendered with an alpha channel or mono color background it'd be alright, but i guess not.)


One thing that really added to it was the sound of the motor revving whenever it stepped, that was really cool.

To play the devil's advocate... :)

The wheels that are spinning aren't random. You'll notice they're on both the arms and the legs. In the interview, he claims they're actually fly-wheels, used to conserve enegry as the robot moves. They spin appropriately in the videos for this function.

There's nothing fundamentally wrong with making sensors and whatnot to resemble the human face... I don't think that this has much weight at all on the plausability of this project.

The HUD... eh.. it's a little hokey.. but actually somewhat reasonable. From as best as I can tell, this guy is claiming to be somewhat freelance, and for the amount of stuff it's claiming to do.. you'd need a HUD with strong feedback like that.

And you could even argue the white background is added to improve visability for the viewer...

Again, not claiming this is real.. just saying it's not hopelessly fake. :p

I know you are just playing devil's advocate, but i guess ill just play... an angel :)

Ok, saying he is freelance might explain a lot of stuff that isnt for performace, but jsut for fun, like flywheels with a rubber outer ring (mr^2.....) and putting work into making a humanoid face, even if that means mounting a radiator in an inconvenient place requiring tubing that has to flex and such. But the freelance thing as a whole destroys all plausability. Look at what Sony, a world giant in electronics can do with whole teams of engineers and massive funds can do, little, 23 inch, Qiro. There is no way that this man, no matter how good BMW engineers are :P could possibly solve the myriad of gigantic problems (i'd say the walking, and the jogging that he mentions, is the biggest).

Okay, this isn't that hard.

Watch the video of the "robot" stopping the car closely. The robot's shadow and the car's shadow are pointed in nearly opposite directions.

The MINI off to the left has severe rotoscoping artifacts, as well.

Actually this reminds me of the news of a live action transformers movie that is supposed to come out. I agree though that does look fake.
