"Eyes. Passive, cheap to run, hungry processing but if you are hauling a body through the air you are paying a high premium already. No wonder evolution has converged upon them multiple times. We have the cams, we have the FPGAs, we suck at…"

"@Andreas,  There is a very large body of work on the problem. Few comments on all of those what you say: About the VI-Sensor: what you read at Skybotix website is true. So it is not a commercial system that a third-party can buy now. But be…"

"@Rob It is not quite as you say. Yuneec is using direct depth data from the Realsense. Here it is very different with having to do all the calculations based on a camera-IMU system. However, a camera is not limited to a very small distance as…"

"Kosta, I 'm afraid the links to the description of the sensor and spec sheet in the page you have linked to above are dead. Moreover, currently googling for the sensor at the skybotix.com site I get: "Thank you for your interest in…"

"Nice work. It's interesting how slow the process here is, and then compare that to the speed with which the Yuneec Typhoon navigated the forest at the CES demonstration.  Makes you wonder what's going on there.  Why such a speed…"

"So, the high-level processor is a dedicated separate board? Could you tell us which one? The vid says something about stereo cams, I assume these are time-of-flight (and presumably short range) ones, only good for indoor applications, correct? I…"

Autonomous Exploration and Inspection Using Flying Robots

Posted on January 28, 2016 at 10:53pm 11 Comments

Hi all, 

We recently released this video on autonomous exploration and inspection. Have a look!

Summary: 

The robot employs its visual-inertial navigation system in order to localize itself in the environment and simultaneously map it and 3D reconstruct it. Based on the newly proposed "Receding Horizon Next-Best-View…

Dear members of the drones community,

For one more year... the time has come! 

The Autonomous Systems Lab at ETH Zurich just released the "Autonomous Christmas Lab 2014" video! Watch and share! Robots are indeed excellent Christmas…

Wireless sensor network control Drones?

Posted on May 11, 2010 at 2:43am 7 Comments

Hello to community!



It is a great fact that UAVs tend to miniaturization. Despite the high technology advances on microprocessors and embedded systems it is clear that only simple control laws can be implemented into Miniature Autonomous Vehicles. Note that i am not talking for rf manned control but for fully autonomous solutions. So what about Wireless Sensor Network control for Drones? It is an idea implemented widely in ground robots. The main approach is to implement on-board only… Continue

Interfacing MATLAB and Arduino

Posted on December 1, 2009 at 7:56am 9 Comments

Hi friends!



I have just found and tested a Blockset that interfaces MATLAB/SIMULINK and Arduino. You may find this at:



http://www.mathworks.com/matlabcentral/fileexchange/24675-arduino-target



I highly suggest this program since it offers rapid prototyping capabilities to the famous and cheap arduino. The guys have build a block that interfaces with the Real Time Workshop of… Continue
