awesome. audi used to have an advert that was one of those made of bits of audi. i'll try and post a link for the video later.
We did something like this in college called the Rube Goldberg competition. We'd have to accomplish a task (like peel an apple), with a machine that wasn't allowed to have any compressed air or chemical reactions. There were also rules about how big the machine could be and how long it took to reset. I think there was also a minimum number of 30 steps, but the objective was to go way over that.
It was quite a bit more difficult than these look since they had free range of space and, in most cases, only put up a sign. In some cases, they just land a ball next to a sign, which is especially easy.
Of course, we worked our asses off on the Rube Goldberg competition, and the machine had to work 99% of the time or you could be guaranteed it would fail in front of the judges.
What else are they going to do, surf the net?Gotta love what engineers do with too much time on their hands.
The Honda ad is amazing, but I have one question. Why do the wheels roll up the ramp like they do? That just doesn't seem right. I can see how the first wheel (the one not on the ramp) could hit the second wheel and make it jump up the ramp a little, but there's no way that second wheel could go all the way up to the third, and then transfer all of it's energy to make the hird roll up just as far. I know it's a commercial, but it ought to be real.
I think they've been weighted. Only a tiny amount of CGI was used (for the reflections on the Accord's windscreen).
It is real. Your mistake is assuming those are normal tires. They're counterweighted and carefully balanced. The weight is balanced at the top of the tire, so when it's bumped, there's enough weight to make the tire appear to roll uphill, but it's actually just the weight moving to the bottom.
