NXT Hand Generator Car

[the0ARCADE0inc]

@skylorz Mindstorms motors can't get broken because they aré designed for that (also think that kids use this kit)

[jontysvideos]

Who does it work without the brain

[meppers]

guys the motors have rotation counters inside them

THEY ARE DESIGNED TO BE MANUALLY TURNED

THERE IS A BUILT IN PROGRAM IN THE NXT BRICK THAT FORCES YOU TO TURN A MOTOR LIKE IN THE VIDEO

[almouloudi]

Why not a long wire for comfortable use .

[secretcinko]

How would that work without the mindstorm brick please reply ?

[gokartracer241]

mine works well

[SuperRugster]

Cute little car

[SeAnStAmOn]

Thats cool

[TheMadspy300]

Is it ok to put motors into each other to cause that? Please reply.

[nxtprograms]

@TheMadspy300 : Sure, we've been doing it for years. Just be smooth with your cranking so that you don't stress the gears inside the motors. Electrically there is no problem at all.

[almouloudi]

@TheMadspy300 Could you clarify what is what you're talking about .

[TheMadspy300]

@almouloudi Ok, Is it safe to connect 2 motors together and use them to convert energy to power one another

[526281georgeyury7]

this is epic!

i never even knew it did that!

[s005005]

it works---realy cool

[nxtprograms]

Hi folks, If you are reasonably gentle, there is no damage to the motor. The gears inside the motor can take some manual turning (just like the motor turns them), and the electricity generated is safely dissipated as motion energy in the rover and/or a small amount of heat (not enough to fry anything). Just crank smoothly to avoid sudden forces on the motor's gears.

[skylorz]

uh.....you are killing that engine

[TheJrEngineer]

Mindstorms runs on direct current, so I'm pretty sure the motor itself wouldn't be damaged, but the electronics could be damaged by polarity change.

[pokerface3699]

@TheJrEngineer the motor could turn either way using the proper brick, so it is most likely to use polarity changes

[jaymie129]

@TheJrEngineer nahhh

[lordthom1]

try it the other way, move the car!

[magemager0]

that messes up the motor because it builds up electricity in the motor

[spectrex1]

If you had the slightest idea how an electic motor worked you'd know that's bs.

[magemager0]

in my robotics tean, my teacher has been doing that stuff for like 20 years, he told us not to roll the robot becasue of that

[dappadcoolman]

not i this motor theirs a built in rotation sensor that only works if you turn the motor

[jakeatollah]

than how come when the motor moves it doesn't mess up the nxt brick?

[brianxia]

just to let u know: lots of ppl said it would damage the motor by doin this

[matthiasvegh]

it's an alternator. if you turn it, it creates electricity, if you give it a current, it turns. There's one in almost every car. it starts the car, and charges the battery. This is in no way harmful.

[MattMagieMania]

ecological ; )

[maribakumon]

cool how u build that

[lordthom1]

read the description

[Legofan4life]

That is so cool!

[kankuj23]

it works

[tahthing]

you can do this with the power funtions i made one for a tiny model to cut down on size.

[jtdreisb]

i wonder how efficient it is

[FuryCaster3]

I didn't even know that wa able to do that! And I've had it for 2 years now! Thnx~!

[remyronko]

WOOW!Incredibly COOL!I made that project also.

[kajan1000]

^^ 5 stars

[legoman909]

cool
