DJ: I will keep that in the back of my mind for future use. Right now only the educators will be operating the robot. We don't want it to go crashing into a bunch of small school kids. I can just read the haedlines now, " Robot runs amuck at musem and runs over several children sending them to the hospital" Thats not something I want to even think about. This has to be able to be controlled with a firm hand and allow the user to quickly vary the speed and stop ot on a dime if a kid gets too close. I was able to do that using the 2.4GHz R/C equipment, but now that I am switching over to the EZ-B, I have to make sure that I get the same functions as with the R/C system.

Kris: I will be talking to you about using the MDFly board. I have two of them in the robot now, but since each can do up to 99 files, I will be pulling one out. I already have it connected to a small amp I built for it. So just need to hook it up to the EZ-B.

Rich & DJ: I will give the Educators the info about the tablet and I will make sure they get a good one and only use it for the ARC and not put any software on it that would impact the operational speed of the EZ-B. I will have them get one with the largest amount of ram , as they do want to use the camera function.

DJ: Would one of these work ? Acer Iconia Tablet W510-1666 10.1 screen 64Gig. or Acer Iconia Tablet W510-1620 10.1 screen 32Gig . I want to make sure that the tablet I get will run the ARC.

I am ready to head out to purchase one.

The 510 should be fine, they are very close to each other (the 500 and 510) with the 510 having the better cpu but the 500 having the better graphics performance.

A quick search found this it should be of some help on choosing between the 2 (if you have the choice)

Rich: Thanks for the input. One other question though. I have a Sabretooth Controller hooked up to my two motors like the manual shows and hooked to the EZ-B as indicated. +5 to +5, Gnd to Gnd and S1 to D0 Signal pin. Using the Sabretooth control which is the up/down left/right arrows. I can only get the motors to go in forward and reverse. I can not make them go opposite directions to turn the robot.

I saw your thread on that, unfortunately I've not used or had any experience with the sabertooth other than what it says on the tutorial pages. I know others have so hopefully when they come on they will see the thread and help you out.

Rich: never mind: I figured it out. Apparently the Preset controls in the Sabretooth Control Arrow buttons are set only for forward and reverse. I had to swap the settings for the left and right controls to get the motors to go in opposite directions.

Got that working, so now I will try using the Robo Claw controller and see if I can get it to work as That one has a hight amperage rating.

After lunch I will be going to get the Acer Tablet, so I can start working with it instead of the laptop.

Thanks for the help
