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

An Autopilot in the clouds - part 3

This article is part three in a series, describing some of the inner workings of an autopilot system - even though the description is specific for this particular system, a lot of principles are generic and can be used to describe a variety of auto pilot systems.Today we take a look at the maneuver system. ManeuversFor each type…See More

"Hi Dan - The stabilisation system (in my case the MultiWii) still resides on the airframe, so even without input from the AP, the craft stays balanced in the air. Also, the MultiWii handles los of signal etc., and makes sure to land the craft or…"

"I think it's really cool that you're doing this, and I'm sure there are some applications for it with which I am not familiar, but I would personally be extremely weary of having a decentralized AP, especially for a multirotor where…"

An AutoPilot in the Clouds - part 2

In part 2 of this blog, I take closer look at the communication protocol, range guard and state machine of the autopilot. As with part 1, this blog post is for those who think developing drone software is interesting and would like to know some of the thoughts that have gone into making this particular system.Some may ask why one…See More

"Thank you Hugues :-) I know there is a tendency here to favour the APM and the likes, for obvious reasons. But we should not forget the DIY-part in DIYDrones and the fun in experimenting and turning concepts upside down.  "

"Besides safety, scalability is another issue here: If you add more drones, it is likely that your radio link gets saturated; and you would need to care about real-time capable medium access strategies."

"You are missing the point. While experimenting with autopilot software it's nice to have the big brains safely on the ground. I've personally lost two planes (and all hardware) while developing autopilot software. You say that autopilots…"

"I agree with @johnkowalsky, This entire community (and this site) is proof that the autopilot is NOT the expensive part of project. "

johnkowalsky commented on Jesper Andersen's blog post An AutoPilot in the Clouds - part 1
"Sorry to break it down to you but this is just dumb. Things like sensors consititute the majority of costs. Autopilots don't require a lot of computing power. It's something that can be done by a <$5 part. It's totally wrong…"

An AutoPilot in the Clouds - part 1

In our RC world, autopilots are typically some kind of software/hardware combination that is physically located on the craft flying/driving/sailing etc.. This has some disadvantages since autopilots are expensive and singular, meaning that they only know them selves and have no interaction capabilities with other autopilots.As…See More

Jesper Andersen commented on Jesper Andersen's blog post In a tight spot - Where would you land?
"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…"

Daniel Minaeian commented on Jesper Andersen's blog post In a tight spot - Where would you land?
"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?"

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)…
