"yes, I'm using opencv and that code is open source, you can see it here: https://github.com/alduxvm/rpi-opencv
Cheers!"
Cheers!"
"Hi Patrick, I'm calculating the necessary velocities using a controller and then sending them to the pixhawk in the local ned frame, I did it this way because is faster, my end goal was not to follow a slow roomba, but it was to track something more…"
"Hi Chris, thanks a lot, I was running APM, cheers!"
Hello everyone! It’s been a while since I write a blog post here!In this post I will explain about a very cool robotics project I did last year. This project is as cool as it sounds: making a drone follow a roomba using computer vision!This has been…
"Oh yes, I have seen that video before, great work! you were using the AscTec Hummingbird right? Beautiful bird indeed!!! that inner loop running at 1khz is super super nice! I always wanted one of those, but my Uni does not have enough budget for…"
"" I guess it would benefit to have the payload position and resulting force to beed back into the vehicle positions/attitude controller?" -> exactly, that is precisely what I'm doing ;) the estimator estimates the states of the payload and its then…"
"I forgot to ask you, when you say "navigation/position control system seems to be significantly under-performant compared to Ardupilot" to what plots are you referring to? how are you making the comparison? if its to the plots of the top views, that…"
"Hi Rob!
Oh yes, I have seen your videos before, pretty intense stuff you're doing, really amazing!. In your application and because your slung is very long, the oscillations of the load are going to be minimal (not so aggressive), that is why is…"

This post is to share a bit of the final experimental work of my PhD, since my doctoral defense is next week... Multirotor Unmanned Aerial Vehicles (MRUAV) have become an increasingly interesting area of study in the past decade, becoming tools that…
"Hi Phi!
Sometimes in PIDs controllers, is a common practice to add a filter on the derivate part, this is to avoid having too much noise from the error and then it will affect the stability of the system... the only stuff is that sometimes makes…"

"I'm sorry for the delay in replaying to this post...
I have several blog posts where I talk and discuss what I call "flight stack", and also the vehicle that I use for this research, take a look here:

I want to show the progression I have done with my DronePilot framework, and in this video I'm showing how to do a trajectory controller.I want to start by saying what I'm using to make this work:Motion capture laboratory (optitrack)Normal…
"Hi Patrick!!
I finally had some time to make some tests using the rpi 3 as well... And I decided to lower the resolution. Allow me to explain why this might work on my application...
My objective is a bit different than yours, but quite similar. I…"

"send an email to EMAX support, they will quickly tell you exactly which ones to remove... every ESC is layout different, I dont have your ESC :S sorry!"
"Thanks Patrick!! :D"
"haha good one!
Actually the disturbance is a good measurement that will help then to re-adjust the gains for the controllers, I have done this (approaching to the vehicle) lots of times before doing this video, and believe me, I wouldn't do it I do…"
