Of all my Nano's 10-9 is the most competitive but I have control issues because it is faster than my reactions.
So I have build a new version with the same 1200 rpm motors but with an extra crown and pinion gear.
This reduces the speed by about 3:1 but then with bigger wheels it is about half the speed of the previous version.

As a side issue is anyone else having problems with photobucket.
They keep saying I have used most of my 2.2Gb of storage but despite deleting many pictures I hardly gain any free space.
They said I was 98.92 % full so I deleted 25 pictures and it only went down to 98.87 %.
I checked my library and I only have 345 pictures so the maths doesn't seem to add up.
It may be something to do with wanting me to go to photobucket plus where I get more storage but have to pay.

Looks very good, especially with the translucent armour :3 To be honest problems with photobucket were what led me to make a 'storage' folder on my web hosting account and link pictures from there instead - less ads, less hassle, but also less bandwidth...

I've started to use imgur. I just upload anonymously, but if you want control - to delete etc., you can get the free pro account.

Hey Peter, do you have any videos of these nanobots? I'm having trouble picturing in my mind just how small they are in reality (pictures don't do justice I'm sure) :D

Here is a quick video of my Leming Nanobot but you still don't get the scale.

So here is a picture against an Ant and a Flea.

Both of those help a lot - thanks, Peter!

How much do Flea and Nano Bots cost you to build in comparison to your ants? I'm guessing that they are around about the same when it comes to building a robot under 150 grams?

I'm enjoying all your logs!

Hi Pete, I've just switched on to your youtube channel, and I've just seen this video:

Is that just a very fast flipper servo, or is there some fancy mechanism to make it flip so?

It is an elastic powered flipper.
Two slowish but powerful servos force the flipper down against the elastic where it latches then the controller returns the servos almost to the other end of the travel.
When I fire the flipper the servos travel to the end releasing the catch and then the controller automatically rests it again ready for the next flip.

Here is the cam and latch mechanism.

Thanks for letting me see those. Many times I've thought of these kind of mechanisms. This is an Antweight I presume, rather than flea?

Yes its an antweight I have had several attempts at this type of flipper and I expect I shall have several more.
It was working quite well and was the first not to flip itself but kept failing to reset after a few goes.
I actually had a look at it a couple of weeks ago and noticed one of the servos was stopping working when it got warm. :oops:
