Symbol Recognition

For the Up The Garden Path challenge, we haven't quite decided if we are going to use voice commands or pattern recognition combined with line-following, (or even a mix of all three! ).

Amy's dad has been looking at pattern recognition and converting some C++ code to Python to see if it was quick enough on a Pi4.

We have previously used Open CV for line following. Amy's dad used the same process back in 2014 for the first line follower code that Ipswich Makerspace's Tractor Bot used, but that was C++. Back then the Pi wasn't really up to it. This example video was using C++ on a x64 PC. 


The next video is from over six years later. In 2020 the Pi4 can match that and do a whole lot better with Python (especially since this is over VNC.) (The cube is a 50mm reject from the 3d printing earlier covered with self-adhesive printed signs).

Add a timer to your video submissions

Image
Part of the recommendations for the video submissions for each challenge, is to arrange for the video to have a timer overlay, like you might see when a sporting event is shown on TV.  We have been using kdenlive ( https://kdenlive.org/en/ ) for editing videos and can recommend it. There are builds for Windows, Linux and Mac and it just so happens that kdenlive can add a timer overlay to a video clip. (Its also free and open source). Amy's dad has produced a short video showing how to add a timer to your challenge videos, using the kdenlive Dynamic Text effect.  kdenlive can also be used to add lead-in, and titles to make the judges life easier. ..and not for the faint-hearted here is the resultant video, including lead in, titles and timer overlay. We will be using this timer technique on all our Pi Wars 2021 videos.

Happy New Year (and we hope its better than the last)

Gripper update. The grippers have been sprayed and a non-slip coating has been added. Grippers The software has been modded slightly to maintain continuous pressure on the block, once the grippers close, and a control button to switch off the gripper servo when the grippers are not closed. This seems to work reasonably well but we might require more tweaking as the cubes are quite slippery. Blocks We now have three cubes of different colours for the "Tidy Up The Toys" challenge. Amy has produced some nice menu artwork including this one for "Feed the Fish". Carping On She will also be giving a talk at the PiWars conference about this and her other digital art, see https://piwars.org/2021-vc/ for details.  Feed the Fish Team Forest Fighters still can't decide how to do this challenge either using a catapult or shove halfpenny methods. Having printed a catapult and launching nerf rounds across the lounge never to be seen again behind the TV, we are thinking thi

Into the unknown with Voice Commands.

Image
Amy's dad here with a quick update on PiWars 2021 progress..... We have busy with other projects so its been pretty quiet on the Pi Wars front, however the basic robot software and hardware is essentially going to be the same as last year (2020) but with added voice commands.  I have been checking out Vosk as a way of getting a Pi to understand voice commands. Here is a quick video showing its not too shabby, especially for single word commands. The main advantage of Vosk is that it is local to the machine rather than using the "Cloud" so even if your cloud service provider is down (note Google authentication went down yesterday for a couple of  hours so not impossible!) you can still command your system using voice. Also it doesn't seem to use much processor (considering I recorded the video over VNC!)
