Re: Direct drive minibot - output diameter?
we removed the gear.

3/8" is in the ball park.

Let's consider if you are currently using a 4" * PI wheel circumference with a 52:1 gearing

4" * PI divided by the loss of 52:1 efficiency would imply about a 0.075" * PI wheel

Efficiency goes way up getting rid of the gears.

We don't recommend direct drive on a heavy robot- it did not work for us on a 4 lb'er.

If any of these ideas help... consider paying it forward. If they don't help, ...sorry.

Has anyone drilled the shafts without using a lathe? I would be curious as to how to get it accurately centered enough and straight in without a lathe.
