We are building a robot mower so we don't have to bear the cold
winter. I have a 120V AC mower and a gas powered mower that cuts
a leveled 20'x40' grass field perfectly fine. I have a remote control
and a receiver capable of a hundred meters that can switch a relay to
get a DC motor to go in forward or reverse. I also have two 8-Amps DC
motors and two indrustrial drill AC motors.

We've never built a mower like this before so we don't know if we should
go
with AC or DC motors or know the best way to transfer power to the
wheels. How should we begin building a robot grass cutting mower?

Thanks

for completely wireless i'd suggest you use the gas mower and an
alternator. you pull the starter cord off and you can usually bolt a
spool to the top, add a pulley under the spool and you have a place for
the alternator to go, which of course means you'll use dc(though not
necessarily).
