I was about to post a few tips on starting to build and use the Six robot in one of the threads (since I just put one together) when I realized the Servo Profile step was missing from the lesson steps. Looking around, the only references to it I found had to do with JD and a couple having to do with loading one from mobile apps. In the lesson steps for the Six, it goes right into making it move from making the connection.

It seems to me there should be a step in there for setting up the profile before jumping into making it move. There is one for JD and setting up it's profile, but that's it. There is not even a note referring to the JD setup in the Six sequence of steps. Given that there will probably be a boatload of Six's put together this Christmas morning (especially since Brookstone has such a terrific sale on them right now) I thought it might be prudent to put that step into the Six lessons. Something like the one for JD (http://www.ez-robot.com/Tutorials/Lesson/33), but specific to the Six.

I'm submitting this thread before I post what I was going to say in the other thread to be sure I haven't missed anything and look like an idiot (once again). Grin

I think this has been discussed before. Servo Profiles are critical for the correct operation of JD, but none of the movements of SIX or Roli are so critical in position to make servo profiles really needed. As long as the servos are calibrated within a degree or so (one gear tooth) than the profile is not really needed.

Thanks for your response. You're right that most of the movements aren't that critical where alignment is concerned. I should probably just forget about it as far as my other post is concerned.

Where I ran into a problem was in the "Shutdown" frame of the Autopositioner control. I like it because it puts the Six into it's most compact pose. Perfect for storage. Storage size is important to me because I live full time in a motor home. If I simply shut it off after that , then no real problem. But I don't. I use it for other things as well and have it hold that pose (sometimes partial) for some time.

The thing about that pose is that alignment is important. If not fine tuned, the pose makes a lot of buzzing noise due to binding caused by not perfectly aligned servos. For this application, at least, the fine tuning can make a good deal of difference.

In addition, I guess I'm just anal where proper alignment, of whatever, is concerned. Grin But that's just me.

Anyway, thanks for your thoughts. They were most helpful and put things into better perspective for me.

Good call @WBS - maybe it will be useful if i modify the shutdown command to release the servos after it has completed. Thanks for the feedback as always!

@WBS, get the latest Six project from the EZ-Cloud. I modified the Shutdown button to release the servos after it has moved into position
