Agreed. The blue types look fantastic and overall looks like an awesome robot. :D

One of the things I noticed when designing the gearboxes for Fleabite is that the motors are very fast and low on torque.
Looking through my gear motors I found some with the same height and width but twice the length which from the sound run much slower and appear to be more powerful.
Also having a long shaft you can mount the motor drive gear plus one of the intermediate gears and the output gear all in line.
This means you just have one other axle with two intermediate gears on it to complete the gearbox.
Below you can see the type of gearbox the motor comes from plus the motors long shaft and the gearing arrangement.

Here is the finished gearbox with wheels which comes out to 70 mm total length and 18 gms. (11.7 gms without the wheels and Tyres.)

I think if I ever tried to do something like that the Universe would wave a white flag.

As per the question in the rules on clusters I thought I had better not put the progress in the rules debate.
I think I have solved the problem of detaching using a tiny 2 gm servo on each botlet.
The botlets look to be coming out at about 28 gms leaving almost 20 gms for the tether / weapon.

Its interesting. "Can detach from each other, but chose not to for the whole fight." I guess that falls into tactics rather than rules. Similar to keeping one half of a cluster out of the way to bring in only if the other half fails to win.
What's your thinking, Peter? I'm guessing some sort of tether so one half can rescue the other from the pits.by pulling them out?
The Idea is not yet fully developed but the tether would also be the weapon.

I can't show you a photo as my daughter has borrowed my camera but here is what I have so far.
Image
Using the RX47 receiver/controller boards from DelTang I can program the second botlet to to respond to the left stick and add mixing to make it easier to control.
Easier being a relative term with two robots and my driving but as Dave has said I could haul one out of the pit with the other. (I hadn't thought of that) :P

Pete attempting to drive two robots with stock Nano drive units at once is definitely something I want to see! :L

I want to see this so much. Peter's driving has improved over the years but this will be something else.
