I ordered the RoboClaw from Pololu, I think. very quick!
I fired up the RoboClaw and my two 42 mm motors on the bench, and that's what it appeared to do. I think APM2 simulates that with the "Aileron mix" mode, as I was suggesting. Still, I'd rather break out the PWM command, and output a simple pair of wheel velocities (as words) instead.

Alan

@Alan,
How long did it take you to get your RoboClaw from the time you ordered it. Basic Micro has been sitting on my order for over a week and it still says "Processing". I finally sent them an email for the status of my order, but so far no response. Maybe they took the 4th of July week off?

@Alan,
The RoboClaw RC funtion should work with a skid steering rover. The RoboClaw expects the pitch (throttle) signal to go from 1.5ms to 2.0ms to go forward and 1.5ms to 1.0ms to go backward just like a regular RC car throttle. The roll (steering right/left) signal will go from 1.5ms to 2.0ms to go right and 1.5ms to 1.0ms to go left. When the stick is centered the rover will go straight ahead at the speed set by the pitch (throttle) signal. Shoud work just like an RC car.
Just a thought.
Regards,
TCIII
Comment by KM6VV on July 6, 2012 at 11:17am I'm after the same thing, but not familiar enough yet with the code. I'm told, 'tho, that one can select "Aileron mix" or something like that, and it will work. Anyone confirm? I think my RoboClaw 15A will take either. But I won't know for probably another week or so. I'm still building the 6WD chassis.

Comment by Niall Dempsey on July 6, 2012 at 10:37am Is anybody here familar with the APMrover2 code? I was looking through the code hoping to find where the speed and steering values are outputed in the hope that I might be able to adjust them for tank steering, but had no luck finding them.

Comment by KM6VV on July 6, 2012 at 9:14am PPP is Precise Point Positioning.
I ordered the LEA-6 right off of the DIY Drones (3D Robotics?) listing right along with the APM2.
But I thing the NEO-6 is more like $175. Oh well.
Alan
Comment by Niall Dempsey on July 6, 2012 at 1:40am @KM6VV: did you order the LEA-6 or the NEO-6? What is PPP?
Comment by KM6VV on July 5, 2012 at 10:26pm Correct. Without.
By the way, the NEO-6 is better then the LEA-6, which has PPP.
Alan

@Alan,
Did you order the APM2 without the MTK GPS?
