"Miniaturization with computation power is the key to upcoming gadgets that will astonish us everytime they are introduced in the market :).

Brief notes about kinect at outdoors:
In outdoors kinect works under shade etc and at under direct sunlight it behaves as a monocular camera (only colour…"

"Hi all,
I have already posted the link of the position controller code (written in the python). I have also been requested by many people to upload the changes, I have made into the arducopter code. Here is the link which describe the functions i…"

"Thanks Shyam for your comments. Here are some flow diagrams of (stabilize)/(altitude hold) modes. I have downloaded them earlier but they will give you a good idea about the controller. Hope this will provide you a kick start to understand the basic…"
"Thanks Helistorm about the link..... They are using WiiController but i can see they are surely going that way..... cellphone as a controller with camera as a optical flow/SLAM sensor.... GPS/A-GPS assistance and long trajectory FPV etc etc........…"
"@Helistorm..... Yep you are right about the revolution these small devices bring ....
its not limited to communication but with HD camera, GPs, Assisted gps, high-level compression, GPRS, inertial sensors and on-top of that low cost + power…"

Smartphones, it seems, can do anything. When researchers at Germany's Fraunhofer Institute for Integrated Circuits were asked to come up with a camera that could be mounted on an eagle to get a literal bird's-eye view of its life, they too turned to…
"dear friends,
please find the code of the "PID position controller for arducopter using VICON measurements" at : http://usmanqayyum.blogspot.com.au/2013/08/pid-position-controller-...
Cheers,"

"small size and portability is the great advantage it offers :)
Robert has mentioned about one video i.e. https://www.youtube.com/watch?v=0h6vniZxwjk

"Thanks,
50Hz is enough as the inner stabilization loop of arducopter is running at that speed (increasing the ground control update rate won't help). As i was using 3DR radio (so it supports well for 50Hz communication). I will add the code,…"

"Thanks for your interest...... Sooner or later i will make it open-source (as i am a big supporter of open-source :) )
We are using a separate IMU, as we require high data rates for position estimation of hexacopter.

@Arseni: it uses vicon (motion capturing system) and onboard arducopter IMU for hovering. Cheers"

Recently we have developed a Visual inertial approach for Hexacopter platform (arducopter) to do SLAM (Localization and mapping----- without GPS or other absolute sensor). The vision node is designed to provide full 6DOF vehicle pose measurements,…
"Hi Cliff-E, thanks for your comment, I haven't experience at bottleneck with 50Hz while using 3DR radio communication.
Though i have to change the arducopter code little bit. Mavlink receiver function (at arducopter side) runs alternatively whereas…"
