As usual, Dodd hits the target dead on.

I have one or two things to add though.

There are other options besides gearing the motors so
that they match free speeds.

You can gear them to match stall torque for example.

Your could gear them somewhere in between these two
extremes -- for example, you could choose to gear them
to match speeds when they are loaded at the level
required to break the tires free.

In every case though, you are only matching the
performance at one torque - speed point. At every
other point there will be a mismatch of some level.

Is this mismatch a disaster? I don't think so. Our
machine in Double Trouble used matching free speeds an
our robot worked just fine.
