Smaller antweight drive?
Can the antweight community hive mind solve this one?
I'm looking for a useful antweight drive system that will fit a (much) smaller track than 2 back-to-back 10mm gear motors. I'm aiming for about 50mm maximum width (including wheels).
I considered putting the motors parallel with bevel gears to turn each shaft through 90 degrees but it all got far too bulky with the plastic gears that I could find. Can anyone suggest a more compact solution?
I thought about the 8mm brushed motors used for micro quadcopters, using very small wheels to avoid the need for a gearbox - anyone ever tried it? I could probably afford to run 4WD, but I'm still not sure how much power they would have.
Small servos sort of work but are *so* slow and the gearboxes in the smaller servos are rather fragile.
Is there anything else? Nanoweight drives clearly won't be man enough and most fleas seem to use the 10mm gearmotors so there doesn't seem to be vast choice of motors about.
All suggestions gratefully received!

Re: Smaller antweight drive?
Are you looking for drive that simply needs to move a weapon about or something that actually has some push behind it?

Re: Smaller antweight drive?
Ideally something with some push, but I'm open to any suggestion to fit in a rather tight space constraint!

Peter had some gearmotors that were this configuration, which might fit: http://www.ebay.co.uk/itm/1pcs-Flip-Typ ... 7pdq-mQzQA

Re: Smaller antweight drive?
Yes I have used them the biggest problem is the small space between the output shaft and the motor.
You either need a tiny wheel and tyre or one big enough to go round the motor as well.

Here are the dimensions.

Re: Smaller antweight drive?
I had been looking at using the motors out of SG90's with MOD 0.4 gears as a form of ultra small drive. Not the most powerful but still some push but you can make it super short.

Re: Smaller antweight drive?
Thanks Scott, those work out a bit wider than I would like, but they may be persuaded to fit
I'll keep looking...

Technobots do a range of the plastic gear motors that have right angle output drive.
They are almost twice as heavy as our standard ones at 19.5 gms.

Hmm, that's a possibility Andy. I might have to resort to some 3D printing for a frame and sprockets, but it's definitely a possibility ![Smile :)](./images/smilies/icon_e_smile.gif)
