DJ - I have a couple problems with the tablet Movement Panel in controlling the dc motors in my R2. I am using the little ThinGeek silver ipad suction cup joysticks on the tablet movement panel.

First - there seems to be no dead-man stop option that I can see. When I release the joystick - the motors keep going in that direction - which is too dangerous for a 180lb+ robot! ;-)

Second - there is no control of motor speed - when I move the joystick in one direction the motors go full speed in that direction - as opposed to my RC joystick control which lets me gradually increase the motor speed. Now this may just be an inherent problem with using these stick-on joysticks - because I don't think they can be pressure sensetive on the touch pad.

Any advice you can offer to get around these problems would be greatly appreciated!!

Thanks
Cameron

PS. Looking forward to the razor fiona tablet later this year as an EZ robot controller. I am hoping the joysticks on it can solve my above problems. See : http://www.razerzone.com/projectfiona
