FYI:  I have started my build thread for my Rover I am building.  If anyone is interested, please feel free to visit @....

Nothing really exciting has happened yet, just testing the APM 2.5 an getting the new body painted an prep'd for the chassis.

Many thanks for your comments.

My biggest problem is I am on a partial budget for a short while an was trying very hard to not spend on something which wouldn't have worked.  But now that I have some key questions answered, I am comfortable with moving forward with this purchase.  It will be bone stock for short term, then I will start investing in obstacle detection an maybe find a way to use my Raspberry PI for determination if it can go over or around a obstacle.

Regarding posting on Rover Group, I have an had no luck.  Which is why I posted here in the Ham group.  Hoping for a better connection as I am a ham operator as well (2m code-less tech)

Now, I am moving forward an will be starting a thread of my build.  My end result is to build a rover which will know when to crawl over or go around a obstacle.

Ah! Clearly I don't know the DX5e (I use futaba) and I feel much better about your plan now. Whatever you do, you'll find an appreciative community if you write it up and post it after you do it. That is what this community is about, in fact, and that is basically how the community was built. Happy hacking. kg4sen

Ahh, I understand your question.  My transmitter has 2 toggles.  One is a 2 position toggle an the other is a momentary toggle for setting an clearing waypoints once in Learning mode.  The only issue I had was the ability to get into Learning mode (or any other mode I wanted).

I'm not suggesting you cannot do it. In fact, for my purposes, I'd like to encourage you to try. More problem solving and variety is good for the community, and would make a nice blog when you've finally figured our what works for you. But allowing you to go forward without asking those questions would also be selfish of me.

Propose your plan in the ardurover group. See what TCIII and the other rover users think.

Comment by Michael Pursifull on April 1, 2013 at 9:22pm
Yes, I understand that. What I'm asking, and what is important here, is the toggle actions. You see, few people at 3DR yet have much experience with rover. And one of the current features that is used in the rover code that is different/less common with the other code bases is the toggle used to mark waypoints or to clear learned waypoints. This is frequently done right now with rover code, and not the others. So it's worth thinking about how that is done with no programmable many-channel remote even with telemetry.

It can be done easily enough with mavproxy and RC override, by quickly pasting in a flip flop of pwm values. But it is not easily done with a mouse and a drop down box. Not well enough to get the timing right.

Mike, per 3d Robotics, if you have Telemetry setup you can set any mode you want via a connected PC on the fly at any time.  When I want to set it too learning, I can set that via my netbook an then toggle to auto or normal via my 2 position toggle.

This also means I can have more modes an not be restricted by my radio.  Since I am building a rover, I would have been happy with a switch on the rover for these 3 modes.

How will you toggle learning new waypoints or clear learned waypoints?
