Juraj Kolesar commented on Sandie's blog post Need your UAV opinion - Connectorless charging capability
"We have made some calculations in this area, but we came to conclusion, that it is not very effective. If you want to come close to charging currents of common drone batteries (over 5000mAh) the inductor on board will be too heavy for this benefit."

Juraj Kolesar commented on Ascent AeroSystems's blog post Help requested! Comments and input needed for new coaxial UAS
"I like your design and dimensions. But is there any way how to make it more convertible for another platforms and cameras? For example I would like to buy the copter, but I want to use RaspberryPi with Navio and it's own camera"

Juraj Kolesar commented on Rob_Lefebvre's blog post Oh Look. Yet another quadcopter goes over $1M on Kickstarter.
"Could this be real??? I am developing similar functionality in larger drones. I don't know what kind of CPU should be inside. But
-return to base and land on man's hand
-face recognition and kind of follow me
-IR obstacle avoidance
-15-20min…"

Juraj Kolesar commented on Josiah's blog post Le Poste in France, and Deutsche Post in Germany using Drones!
"All those delivery drones videos are still more hoax than reality with standard GPS accuracy that can vary up to 30m."

Juraj Kolesar commented on Aleksei Ivanov's blog post Design feedback needed
"Just a few physic laws and expressions and the calculated efficiency of all that additional stuff to standard quad will be nothing or negative. At least with proposed proportions."

Juraj Kolesar commented on Alican Kurutepe's blog post A new controller project
"I think size is ok, for development purpose. I am looking forward for documentation review"

"Great work, I have been missing this long time ago"

Juraj Kolesar commented on Laser Developer's blog post Wide angle laser beams for anti-collision
"@Rob - what kind of sensor and firmware are you using? Maybe I just didn't catch it from the video. Is it kind of OpenSource project where I can participate, because I'm working on something very similar."

Juraj Kolesar commented on Paul's blog post DJI INSPIRE 1 in Action
"I don't know why previous post about Inspire1 was pulled back. So I put it again here. Inspire1 is for sure nice piece of work, but I think more important for DJI and for the small UAV comunity is reveal of http://dev.dji.com. "

Juraj Kolesar commented on dusl's blog post THE NEW CONCEPT UAV
"I don't think it is inovative at all. Guys from boeing has it already flying

Juraj Kolesar commented on Patrick Duffy's blog post How to build a High-Definition FPV UAV using a Rasperry PI with HD camera, using a high speed WiFi link
"Nice ideas. I am playing also with RasPi cam with good results. We have RasPi with USBwifidongle onboard, which has at least 2x bigger range coverage than the 3DR telemetry module. So we thought how to transmit telemetry via TCP-IP. Serial to…"

Juraj Kolesar commented on Juraj Kolesar's blog post Automated touchdown navigation without GPS
"@Randy - we are trying to develop it also on fork of Arducopter code. Possibly for the future, we want to share this code with community as a new type of flying mode (kind of alternative to RTL) using our sensor technology.I tried to to find some…"

Juraj Kolesar commented on Juraj Kolesar's blog post Automated touchdown navigation without GPS
"Inertial navigation would be really useful as additional information to tune up the landing procedure, but according to discussions found on diydrones APM2.6 has not enough processing power to handle it. Our goal was to use as least additional HW as…"

Juraj Kolesar commented on Juraj Kolesar's blog post Automated touchdown navigation without GPS
"No camera signal. We have tried it also this way, but there were issues with camera stabilisation and picture recognising has high demand on CPU power."

Juraj Kolesar posted a blog post
http://youtu.be/SoS2VBvRCAQWe are developing a technology for automated landing navigation without GPS or better to say with higher accuracy than standard GPS signal. I think, there can be a lot of various utilisations of such technology in…

Juraj Kolesar commented on Chris Anderson's blog post 3DR, Amazon, DJI and Parrot join up to form the Small UAV Coalition
"I think there are always two sides of the same coin.
1. Together you definitely have enough power to affect public perception and law creation, this is the cool side.
2. This sounds to me like cartel agreement, which can have negative influence on…"
