video Make a better Bristlebot!
If you have ever made a bristlebot, then you have properly also seen it fall on its side, over, and over, and over again!...   
Well, this will show you how to make one that will not fall!   ever! :D

A bristlebot is very easy to make and will skate over any flat surface when done.
A bristlebot is also tons of fun for kids.

Why does a big head teethbrush goes faster than a small head teethbrush? When you race them?
I love how simple this is!
what size and type of nails do you recommend or does it not matter since they are only to balance it out?
Wow!

SO AWESOME!!! but how did u figure that out? :)
love it
peterjacob (author)  gabouzeid3 years ago
well, its center of gravity was pretty high, and that makes them fall over all the time, and i got tired of my bots allways failing ;)

so i thought i could improve it, and i tried some different stuff, and the nails worked best :)

what if you screwed the 1 tooth brush in the middle and added one on each nail?
peterjacob (author)  nubabuba3 years ago
hah, i bet that would clean better than 1 brush :D
sure that would work, you could try it! :) id love to see it!

and yeah, it would clean, a little. good luck! ;)

ok that is a great idea. but the question is.... would it clean if you put water on a table and let it zoom around?

ok i fixed the problem. I just need to get it to go faster with a new battery and get it to be balanced better.

Love love this! My son (7) and I built this version of the bristlebot today - it went amazingly smoothly. Thanks for the idea! Here are pics and video of the build (and the tale of the unhappy ending).

 Nice little vid. I dont have a pager but lots of toothbrushes, maybe one with a vibrator from my dead dualshock? That is like no sandwich I've ever seen!

ok got your point.thanks!

why dont you make only a nail bot?? metal will handle vibration more efficiently?
is there really need of the toothbrush??
The backward facing bristles on the toothbrush are what makes it go.  If you just did the nails with the motor, it would just sit in one place and make a lot of noise bouncing on the table. 

Now, if you were to somehow attach bristles or otherwise rough-up the two back facing nails, and smooth the front one, you might get some motion... interesting notion...
