Weird behaviour of HK KK 2.0 board (LCD version) in pre. flight tests

Started Dec 29, 2012 0 Replies

I have just replaced my old kk board with a HobbyKing KK 2.0m board (quad x-mode)The ESC's was already calibrated from the old configuration (no need to do that again right?) - I calibrate the gyros…Continue

"GPS and GIS can't tell if someone parked a car or some construction work is going on at the landing spot. The whole idea is that the drone should be able to find a spot based on how things look at the time the need arises. Also, the drone might…"

"This is defiantly an interesting idea. However I just have one question, wouldn't it be easier and faster for the Drone to use GPS and GIS to find a good landing spot?"

"Thanks Jay. I will do an update once I get a chance to test this in real life OR when i get it ported to the Parallella computer."

"This is fascinating, and not just for drones either.  I'm currently training for my PPL, so if this gets to the point of being operational and fine-tunable for larger aircraft, particularly finding clear spaces large enough for, say, a…"

"Great post and great idea!  Felixrising is right in that we don't have an interface in ArduPlane/ArduCopter for dealing with image processing sensors.  This is very much on my mind these days because for sparkfun we need a way to…"

"yes, precisely the same place, and it took me about 5 seconds, but I was a bit distracted. If your code can get it in ~850ms that's pretty good!"

"My memory about IR vs Visual is really shaky, and this might require a secondary sensor - or a camera capable of seeing both visual and IR - but isn't there a differential between water in visual and water in IR that you could trigger off of?"

"Ya there are actually a lot of factors that go into what color a body of water happens to appear at any given time. Particulate matter from runoff can make it all brown.  Tannis can make it brown to black. Clean fresh water can vary depending…"

"Very clever. I was briefly involved in simple contrast-based machine vision development in the 90's (tool identification and selection) but your addition of color to an algorithm is brilliant. Can't wait to see where this goes. "

In a tight spot - Where would you land?

I magine your drone suddenly running low on power - a long way from home, doing it's auto waypoint flying thing.

You have to decide how, where and when to set it down very quickly!

I've been playing with my homebrew Automatic Landing Finder (ALF)…

Processing power for Drones!

Posted on February 15, 2013 at 1:30am 7 Comments

Ok - so the critical sub systems for keeping balance, headings etc, are probably best served by a RISC type processor like the ARM and ATMega processors. But on top of that, you could put something that allows an easy access to image processing, communication, logging etc.. In the…

USAV - Telemetry system

Posted on February 10, 2013 at 1:20am 0 Comments

USAV is the Unmanned Social Arial Vehicle - A drone with an android based auto pilot system that communicates through Google talk and Twitter. Due to the weather and the fact that an H-frame is being built for the vehicle, no flying is possible here. But I'm making good use of the wait :)

So snow is still falling here in the north and it's not really flying weather.

So I decided to make good of the waiting and create a telemetry unit for the USAV.

I…

USAV - An architectural update + video

Posted on January 7, 2013 at 6:18am 4 Comments

Here's an update on the USAV project I started some months back. This post is mostly about the architecture and features of the current version as well as a video of a static test.

The USAV is a UAV with an integration to some of the social networks like twitter and Google talk. It is also an…
