Drone following a roomba

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 done before and for sure someone has posted their on solution here, I…

Slung load controller

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 allow for positive changes in today’s world. Not having an on-board…

Trajectory controller using a companion computer and a naze32

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 quadcopter 
  • Companion computer (raspberry pis and…

DronePilot - Position hold controller

We all love drones, and we love to just buy one and go outside and make it fly by itself, this is great. But what is actually going on inside the drone?

In this post I'm going to explain a bit how a loiter controller works, with the difference is that I'll show my controller, share the python code and that I'm using a motion capture…

Flying from computer

As a by-product of a research I’m working on right now, I’m showing this videos of me controlling a multirotor from a computer. Its done in different multirotor platforms, two flight controllers, Pixhawk and MultiWii.

So, the basic idea is to send data to the companion computer and then the companion computer will use it to several purposes.…

Drone color tracking

This is about some experiments I’m doing using python and openCV and of course one of my drones… In this case the drone used for taking the videos, was my hexacopter (Alduxhexa).

The point is to explore different techniques and algorithms to track colours, objects and the…

How a quadcopter is born?

How a quadcopter is born? from Aldo Vargas on Vimeo.

This educative video shows how a quadcopter is born, and of course its maiden flight. 

I had to built a quad with some parts we order from hobbyking, so, I took my camera, put it in a tripod, read some…

Quadrotor indoor position control

This large video is about the project that Murray and me have being doing in the MAST Lab. It's about doing automatic position control and trajectory tracking of a micro unmanned aerial vehicle, being more specific is our 3D printed quadrotor platform,…

3D printed quadrotor frame using Rotites

This is yet another version of a 3D printed quadrotor, pointed to be one of the workhorses of my research... The main characteristic of this frame is that instead of using nut and bolts to join the arms and the base together, like in TEGO v2, I'm…

ESC and LiPo problems, fuzzy control stopped...

Hi!!


How are you??


New problems!!!! big problems!!!!


In our last neural network training, we had a accident, i crashed the helicopter, hehehehe


So, we rebuild it, we just change the blades, and the blades holders, that was all the damage, lucky us...


But with the new blades installed, we had to track them, so we try to do it, failure after failure, so we stopped,…

Neurofuzzy helicopter problems

In my last post, i had vibration issues, remember??


So, what did i do to resolve that??


- First, we design a better place for the sensor to be, it uses elastic bands, that improve a lot the readings, but we still had glitches on the angles.


- We change from DCM to Kalman, because the performance of Kalman was better, and faster.


- We use a second filter, we implement a simple digital…
