"I don't think you'll get nearly the precision you're looking for, especially since you need absolute positioning, not relative. If I were you I'd look at a kinect (I heard that there is a smaller version available). Good luck!
"I'm answering your question below (for some reason it doesn't let me answer the question under the question). My tune was done manually, as autotune was apparently enough to trigger the motors shut-down bug. Now that it has been solved, I may very…"
I appreciate that you don't let it "slip". I'll be keeping an eye on it after 3.2 is released too. In the mean time I'll disable the climbing phase. Tonight I thought I saw a twitch in the descending phase. Since it's first time that I…"
"Ah - I didn't know - navigation was just reworked in 3.0.1 and I assume that it will stay like that for a while at least - I like quite a bit the way it works (I tried 2.9 and didn't like it), so I'm surprised to hear you're revamping. As far as I…"
"I know Jay. There were two bugs:
- first causes instability (the twitch) on RTL in the climbing phase
- the second one causes the motors to lock down on large throttle/roll inputs
Patch 3.1.3 rc1 fixes the second bug, but not the first. That's…"
"Is having the APM centred important? I thought a bit about it and I thought that at least the accelerometers ought to show about the same values, and if not calibration would take care of it. I have to say that stability is usually just fine. The…"
it's a bit of a pig - AWU is 2kg (4.4lb). It's a hex X frame, using Turnigy Talon 2.0 carbon fiber frame (super-sturdy BTW - heavy but very strong), with a 3S 5000mAh nanotechnology battery, 800kV motors, 20A Turnigy Plush ESC.
