I took R2 on the front porch today and drove him around some.
His foot motors are wired for 12v. and they are working GREAT!!!!
I was also testing the range on the PS2 controller and it was
pretty good, Since the receiver is inside R2's aluminum body.
Seems like the maximum range is around 40 feet.
Now that's from my porch, out of my front yard (15 feet)
across the street (15 feet) and about 10 feet into the neighbors yard.
If I held the remote up high, I could regain a signal.
That's not bad for a cheap PS2 controller and I never intend to get
that far away from him while driving. :o)
With the Cheap Controller (C6C)
and a Sabertooth Motor controller
I don't think you can go wrong with the price of both parts.
I'll post a video of R2 in the street when I get a few more things completed,
He's not ready for any real exercise yet.
