Step 9 VIDEO of The Ball In Motion

Here's a Video of the Basketball In Motion

And here's one of the hamster ball without the basketball so you can see the insides.

try making it small enough to fit in a tennis ball and post the instructions. if you already have and i missed it pleas say so.

very supercalifragilisticexpialidociously cool! can you play basketball with it whitout destroying the inner technologies? 5*

First of all the ball won't bounce. Second, it would probably destroy the steering servo pretty quick. When taking this ball to the park I have to say it's VERY hard to walk with a ball in your hand and not bounce it. -Peter

[necropolian]

and if it could bounce without 'pushing up the daisies' it still would be useless because you can't control it when it touches the ground only fractions of a second. and on bumpy grounds it would be a pyrrhic victory if you were able to bounce it into a specific spot...

[bsamuels453]

it doesn't need to be on the ground in order to change the ball's trajectory, just wobbling the steering chassis back and forth would create a noticeably strange effect

[necropolian]

but still, it is much less controllable in midflight. the steering has more effect on solid ground. but it is still very cool.

It was designed for use by the Harlem Globetrotters on a basketball court. Very flat, very even and very level. It would be physically impossible to build a small ball that was capable of much "off road" type driving. Not becasue of abuse on fragile equiopment. That could be remedied, but because of physics. The rotating mass inside has limits to how aggressive it can be. You can't just put in a bigger motor like in a car or plane. A bigger faster motor just makes the inner mass spin around, up side down, inside the ball. As far as bouncing. I've thought of making a ratcheting spring that pulls the mass down and then a trigger to release it. I doubt it would "jump" more than a cm off the ground and would add a LOT of weight and complication to the already delicate assembly. So, I hope to see someone do that some day but I'm going to leave that idea alone for now. Thanks for looking and the comments.

with bouncing i mean that it can survive a bounce, not bounce by itself. i think you can place the ball in a larger ball, by connecting it with rubber bands to the inside of that bigger ball. the rubber bands absorb the shock.

you stole my idea!!!!!!!!!!!!!!!! GRRRRRRR!!!!!!! i made one of these out of lego, but i did not have a ball to put it in, so that was made of lego too. still, you stole my idea!

[prabbit22m]

Yeah, I've been stocking you for the past several years for the soul purpose of gathering information on your lego ball. hahaha There's always many ways of doing things and there are many instructibles of similar projects. You should make an ible of your invention! I would love to see it. BTW, I wasn't aware that lego was now making a gyro and proportional servos.

[notanemo]

i destroyed it so i could make a knife holder that you attatch to your arm so when you swing your hand in a certain way the knife shoots out and hits some one............... and no, they dont. it was just two normal lego motors conected to a lego hail-fire droid's weel. one of the motors was connected to it so the weel swiveled around the whole thing, and the other moved the weel in a circle so it could turn. the rcx 2.0 'brain' was at the bottom to act as a weight so motor no 1 could move the thing. the weel was connected to a series of 6-stud beams that where in circles around the weel to make a sphere. but it is dead now...

[Darkknarf]

Then you should have posted it.

[phirzcol]

Such a device of wonder. Hmm to use for good, No to use for evil Muahhh haaaa haaa. When do we get to see the prank videos?

[Hayhick]

How do you re-charge the car

[neardood]

i reckon that is the coolest RC thing but it obviously has its uses for pranks such as ghosts or just for a laugh

Teen 1: Lets shoot some hoops. . . . . Hey there's a ball.
RC watching: Start ball rolling
Teen 2: Hey, come back here!
