[ausev] 2 motors - serial vs. parallel

[lyle sloan]

Thats a very interesting idea with the motors in series.

I guess when turning left or right you could decide which motor will be first in the serial, but how would you control the torque/amps per motor?  Variable caps in parallel to each motor?  A chopper in series to each motor?  

Sounds easier to maintain the wheel motors in parallel and do the sensing and control per motor via a variable resistor.
