Hello Im back. I just wanted to give you an update on what happened with the Sabertooth. I spoke with Dim. Eng. and they replaced it with no problems. I worked on the Tank Mode Test program this morning and the motors ran fine. I do have a couple of questions for you.
You know on Ch1/Ch2 you have to take out the red wire I noticed on my Sabertooth the other two wires are a little loose (blk/org) in their output plug. When I first ran the program it was doing the same thing as before and I couldnt believe it
When I took a closer look at the plug is when I noticed that the blk/org wires are a little loose. So when I slightly push them in the plug while running the program no problems at all. I just have to figure out a way to keep them securely in place from now on. I dont think its that big of a deal, but if you have any ideas to them in place thats cool.
You could replace the cables, but beyond that, I don't know how to fix the cables you have.
Well...while I was waiting for my Sabertooth I was working on my arm with RIOS and you know before I can do that I have to modify the arm 30 degrees in the arm assembly which I did and also calibrated the arm in RIOS. Now my question is back to the tutorial http://www.lynxmotion.com/images/html/build148.htm
moving on to Step 11 Servo/Motor Control Calibration. Going through the program and finding the offsets Step 13 says place the robot in a position as close to neutral as possible, and turn it on. The robot should go to and hold the neutral position, and should resemble figure 13, which is 90 degrees. If the joints are off by more than 15ï¿½ you may have made an error in assembly. If Im not mistaking its not going to be at 90 degrees its going to be at the modifications that I made for RIOS, correct? If so do I continue with this tutorial first and make it 90 degrees and then start back up with RIOS again?
The modification is only required for using RIOS. If you are not using RIOS you must put the elbow back to 90Â°.
One more question after I make it wireless will my robot run by the Bot Board II and not SSC-32. I was just wondering because Ive been using the SSC-32 for RIOS. I noticed in the manual V1.06 Ch. 8 it talks about the Basic Atom 24 and Bot Board. Is this where I make my modifications? I also found this in the forum viewtopic.php?t=2401
. Is this something to consider also?
RIOS allows you to create a program for the Basic Atom that essentially replaces the PC. It will send the same commands the PC was sending for a particular project. This is generally considered a fixed arm system, I.e. the arm is stationary... The tutorial you are following is to make the arm work as a remote control manipulator on the 4WD Rover, a mobile platform. It has no association with RIOS.
