Simple Bots: Rolly

Step 7 Insertion

Pass the bristlebot through the slit. Pull out the blue tab from between the battery and the holder as to turn on power to the motor.

Your bot should now be free to roll around as it chooses.

Where can I get/buy these kind of motors you used?

[Dearden805]

You can buy them at radioshack for real cheap

[lalaman]

Try any console controller like an XBOX controller or PS2 controller. It helped me :)

[TigrisLi]

You can find a vibrating motor in a electric toothbrush

[huksin]

i think in a cellphone that's what i got

[Lawlzdeep]

A switch that can't get turned on/off accidentally would be a nice addition

Does the bristlebot inside ever fall over?

[Lawlzdeep]

It seems that if the center of gravity is low enough it will always correct itself, that is if the bristlebot is big enough to never fall fully on its side without bumping into the inside of the ball.

you have know simple robots.

[wareneutron]

you such a good work

[toofless]

it looks like it would be great for a dog to chase around... but, couldnt you just put the motor and batteries in the ball for the same effect?

it's a bit more jerky and random with a loose motor in there as it may sit in place for a long time, fall on the counterweight and stop spinning altogether for a moment and then spring up and suddenly change direction (for instance). By doing it this way it is "driving" and causing the ball to roll a bit more smoothly.

then gust add some super tuff 2 sided tape to the motor. =)
