Re: Working FPV Camera setup with realtime HUD

Hey omwdunkley, I am a big fan of what you have done with the crazyflie so far. I am trying to implement a live camera feed and hopefully some ROS and OpenCV algorithms using most of the same hardware as you. I had some problems with our transmitter initially (It may be too heavy or it might just d...

Re: [Video] Alternative Kinect Control (using depth images)

I'm just getting going with this project. I've installed most of the software and now a student and I will begin trying to get it to work before we try to add to it. I'm sure I'll have several questions along the way. My first is this: will the custom firmware work with a CF 2.0? Thanks Oliver for ...

Master Thesis: Visual Inertial Control of a Nano-Quadroto

Hey guys, I finished my master thesis up this summer. Kinda forgot to post it here. Oops. Maybe there is some interesting stuff in there... Visual Inertial Control of a Nano-Quadrotor PDF ( University Link ) Video for IROS It talks about how to add a camera to the crazyflie, how to use the camera to...

Re: A possibly good, cheap, and light FPV setup...

I just saw this post on Hackaday about a very small DIY FPV camera setup for under $100USD. I haven't read through the whole article yet (the one at flitetest.com) but I'm thinking this may be a good FPV setup for the CF1.0 (and maybe 2.0 as well). Thoughts from any hardware guys in the community? ...

Ill be returning to Munich this month and will only have a single job then :) I should have time to help with whatever problems are occurring... I hacked most of this together while writing my thesis so it is not real...

Re: [Video] Alternative Kinect Control (using depth images)

Hey guys, sorry been super busy with my day job, hardly have had time for the flie at all! Also managed to break my arm..cant really type! I did not catkinize the package yet, so running rosmake is the way to go now. This basically build the messages. If you change the firmware (add logging configs)...

Re: [Video] Alternative Kinect Control (using depth images)

It seems no problem for y axis and not so unexpected result for the curved x-axis (the curvature of depth field) but need to be fixed anyway. The error for z axis is quite large (both error and spread) but so far the control in z axis is the best from 3 axes, maybe due to the fact that it is just t...

Really like your work on this - awesome! Thanks for sharing.
So you run the joystick polling frequency at 30hz and its better?
What sort of PID values are you using?

Cheers!

Re: [Video] Alternative Kinect Control (using depth images)

Some more investigations showed me that trying to do screencast uses quite considerable resources and cause some delays. Without doing that (and a little bit modification on numpy matrix manipulations - not sure how much this helps), I experience the delay less; most of the time no problem, but som...
