Hi all,

I'm glad you like the video and pictures. Hopefully again in Sinsheim and Schoonhoven.

Hi, I've made a compilation video (~30 minutes) and 48 pictures of the convention at 11-05-2019 in Twello. With 11 people with models, it was a small venue in a local library but still a nice number of people visiting. Video via Youtube: https://youtu.be/V_brlj4MjFo Pictures via Flickr: https://www....

Hi Carel,

What about using Flickr? I post my pictures on there as well.

Hi Richard,

Will the USB camera work again via Python? After a firmware-updare during the Dreieich convention, the camera didn't work anymore and "something" had to be fixed in either firmare or ftrobopy.

Hi Torsten, As I understand, the distance value decreases while the counter value increases. However, after quite a few tests, I find that both values decrease. Can you explain why this (seems to) happen? From my latest test, I've saved the datalog. BTW, the forum doesn't allow the upload of files w...

Dank je. Ik ben blij dat het (in Dreieich) aan de geheugenkaart lag, en niet aan de camera.
Dus ik hoop nog vele foto's en video compilaties te maken (Twello? Wedemark? Sinsheim? Schoonhoven?)

Hi, I've made a compilation video and pictures from the convention in Veghel, NL. Very good setup, lots of visitors. Even local and regional TV visited.

Hi. For some time I've been using the HSV colourspace conversion of OpenCV to separate colours in a by getCameraFrame() grabbed image. Although this does work nicely and I can view images, when I send or open an image (using GIMP or ImageMagick) I always get the error message "Premature ending of JP...

Hallo Thorsten,

Dank voor je reactie. Er was iets fout in de link, zou nu moeten werken.

Groetjes,

Hi all, I've made pictures of all models and a compilation video of the moving models at the Schoonhoven, NL 2018 convention this weekend. This time, the memorycard didn't stop working... https://www.flickr.com/photos/89022424@N07/albums/72157697020658040 https://youtu.be/k_htqg0-SPg Hope you enjoy....

Hello Peter,

Times like this make you realize that technology can fail at the moments you need it, so by now I have 2 memory cards. Thank you for enjoying my videos and you're welcome for the photos.

Nice video, which seems to be taken during setting up the models.

Hi, I was prepared to make many videos to put into a new compilation video and many pictures, but after taking only 12 pictures, my memory card gave up. Without spare and none for sale in Offenthal, I realize a lot of people will be disappointed, considering the reactions I received during the conve...

Hi Torsten,

Thank you for the explanation.

Hi Torsten, Thank you for the feedback. After changing the wiring, getCurrentDistance() indeed returns a value. However, I now notice the strange effect, that from 3 distance readings on C1 and C2, the first gives e.g. C1 = 160 and C2 = 140, then 160 and 0, finishing with 0 and 0. Running the script...

Hi, I have a problem using getCurrentDistance(). According to the github manual, it should return the distance, but for me it always returns 0 (no matter which counter it's connected to). When I use getCurrentCounterValue(), I mostly get the expected counter value. Here's also a strange finding: whe...

Hi,

I've made a compilation video (almost 30 minutes) of the 10 March convention in Hoofddorp: https://youtu.be/wyhhBbY_7b0

- when running the cfw the ft-GUI has to be started before any ftrobopy camera function (startCameraOnline, stopCameraOnline, getCameraFrame) can be used. Now both camera functions and the motors work again, when the ft-GUI shows on the display. But this is not how it works on my other TXT running ...

My problem is that the code I use for running my walking model works great on the default fw, but not on the cfw. I've checked using an oscilloscope, but there's no signal at all coming from the motor outputs when the cfw runs. With the camera, I know both controller and camera work on the default f...

Nice to see that the development continues. Question though: since the installation of 0.9.3 on 1 of my TXT's, the motors and taking images aren't working anymore. On my other TXT with 0.9.2-4, everything runs nice. Since I don't like downgrading cfw, which 0.9.4 version should I take as it's not br...

Hi thomass, Nice to see your efforts on CFW and ROS. I'm using Python and ROS with a different experiment involving RaspberryPi and may start doing it here as well. On the error of the camera thread: yes, that's my experience as well. Either connection to the TXT is aborted, the camera thread is cut...
