Perpetual Motion Seesaw Robot

Design Lab, McGill

Built a seesaw using the Lego NXT robot kit. The NXC algorithm detects the ball with a light sensor and calculates its velocity. Based on that data, the servo is rotated and uses a simple crank mechanism to rectify the motion in the opposite direstion.

Next best thing to perpetual motion!

[411HowTo]

but the NXT needs energy to run

[zebenwan]

No it doesn't.

[therealcedz]

this isnt perpetual motion.

[reverbflange]

@zebenwan What then powers the servo and NXT?

[kawregis]

Misleading!

Please give up science. You would have a better chance in the "how to get unwanted attention" business! Perhaps you could video you farting and call it earthquake in Japan. This surely would annoy a lot of people. That is what you want isn't it?

I agree, zebenwan is not smart at all. Not even funny. Just a spoiled child with a bad attitude.

In other words... an idiot!

[rkjpsn]

whatever, this is cool. everyone should just chill and stop pointing out that this isnt a true PM machine

[kingofthebacon]

@zebenwan yeah totally and birds fly out of my butt and i throw them at old people wearing cardigans yep exactly!

[timjamesmackenzie]

@zebenwan so rename the video. call it shit vid with crap ending

[vo7tage]

Maybe you shouldn't call it "perpetual motion", as this can be misleading. How about

"harnessed physics".

[FarceTheory]

Look ma no hands!

[Jaronschoor]

Wow zebenwan is not very smart. A perpetual motion machine is something that work's without energy from an outside force.

-First he claims that it doesn't require energy to run

-Then when someone points out his stupidity, because it requires batteries, he insults him!

[nrdesign1991]

@zebenwan how about batteries placed inside it
