Made various mods including smaller crankshafts with less throw, smaller batteries 2 x 60ma and new lighter shuffle plates.
This gives a much better action which although slow is useable.
All up weight is now just under 28 gms so almost 10 gms to play with if I decide to add any armour / weapons at a later stage.
Here it is up the right way.

Here it is in the now complete nano team

Here it is in action which has lost a a bit of the comedy appeal.

It's almost just vibrating along :L Are you using two cells just to get some more speed out of it?

Dave I did say it had lost a bit of the comic appeal it doesn't flip on its rear any more.
Rory I took an old controller out of a previous version of Combatant which is a DT receiver with DT driver boards and a 5v regulator so it needs two cells to run.

I have added a scoop to the walker but because of th cube restrictions it has to drop down when it starts.
It is held in the up position by a catch that is attached to one of the shuffle plates which releases when the robot moves.
Here it is with the scoop up.

Here with it down.

And here in action.

Even with a bit of brass in the scoop to ensure it drops properly it is still only 30 gms.
I have run out of numeric versions of Nano so I just going to call it ARENANOISE.

Looking great Pete. I really must get myself a Nano.

Slightly off topic - and correct me if I'm wrong - but it looks like the scoop was printed in 3 pieces? What adhesive/solvent do you use to bond the pieces together?

I find with ABS normal plastic cement is the best it basically desolves the surfaces together.
The one I have at the moment is Humbrol Poly Cement.

Finally got back to some robot work although with 32 packs of laminate flooring arriving today it might be short lived.
I have for some time been considering designing a gearbox for the nanos based on the small double motor units I bought some time ago.
Having spoken to the Reading boys last saturday and seeing Will now offerers one on his site I thought I would have a go.
I wanted it still to be a double unit but wider and shorter with an extra gear to slow it a little and give more power.
Here is what I have come up with it is 49mm tip to tip but a wheel should go around the gearbox without increasing the width.
Image
Mind you we now have 60mm to play with and there is always the diagonal.

Yeah, that's pretty much what I'm working on atm, although I would cut that bar at the back down to save weight... The 5 stage boxes are much more torquey and controllable as shown by Fite Me M8; I'm planning to upgrade Chug and 'Moon to them at some point as well... Should have enough torque to move an ant too so could be good for setups where powerful drive isn't a requirement but weight is a premium (eg big spinners ;) )
