Altitude Hold in Simulation

Started this discussion. Last reply by Steven Gates Oct 30, 2011. 2 Replies

The altitude hold mode in V2.049 looks very promising in Jason's video.  However, my altitude hold does not work very well in simulation.  As I turn on loiter, my altitude rises and falls with a…Continue

So is there any test code for obstacle avoidance posted online?  I would like to have something to start with but I am unable to find any code.  Any help?Continue

Actual Quadcopter weight..

Started this discussion. Last reply by Michael Pursifull Sep 18, 2011. 1 Reply

Can someone advise on the actual weight of the Quadcopter ( Product Code: ACQ11ARF ) from jDrones.com ?  I'm planning on entering an RC competition that requires the weight be less than 1kg.  I am…Continue

"Pretty impressive, wonder if they have mapped this whole area with that short range lidar they have mounted on octacopter. Still $1,000 for the unit is an overkill if only used for obstacle avoidance unless you do some 3d Mapping with it like they…"

"There are several test videos on youtube already. One most advanced system that i have seen is from Phoenix Aerial. They have small LIDAR under their Octo copter and they are getting nice readings out from it.  Phoenix is not only system that…"

"Nope, there are several companies making small lidars and some of them are already starting to work. Ok they are not going to be free for sure. Smallest Lidars are really small. Something like 50mm diameter and 80mm high full 360 degree lidar for…"

"Lidars? Oh no that sounds more like in 10 years :) Lidars are pretty expensive and the latest area of usage I have heard is self-driving vehicles like Google Car. But if that eve happens it it would be interesting. Then we can use lidars for other…"

"Not really. There is still some sensor issues that needs to be solved first. Most likely proper obstacle avoidance starts to work when LIDAR systems are getting better. There are several projects going on this area but nothing is released yet. Most…"

"Hi Kal, you may find this paper useful. In this paper, some obstacle avoidance scheme with a few Sharp range finders and a maxbotix sonar was implemented. Do cite this paper if you find it of any help. Thanks a…"

Kal replied to Steven Gates's discussion Obstacle Avoidance
"Hi Steven, We're looking at using doing sonar-based obstacle avoidance using 5-6 Maxbotix range finders and writing some code for it. Would you mind sharing? It would be great if we didn't have to write it from scratch."

"Currently there are none working ones. System that Jose played long ago is too inaccurate for production so it's development is temporary paused. There are some interesting sensors coming and if/when they come, we can look this thing again."
