This past weekend was the Orlando Mini Maker Faire at the Orlando Science Center. I am not sure of the final attendance numbers, but I was busy the entire time. I brought a total of 15 robots to display. Naturally I had the Shuttle and segway bots, but this event featured a new NXT project in partnership with The MathWorks, makers of MATLAB and Simulink. The video will be coming (due to poor lighting at the event, I am having to shoot the video at home) but the project features control of the NXTs from MATLAB. Navigation is done by processing the image from a camera positioned above the bots, as you can see in the first picture. I will go into more detail soon, but The MathWorks provided a good foundation for the demo and I then added a few enhancements. The code running on the NXTs was written in Simulink and the image processing and control as in MATLAB. The bots communicated with the computer via Bluetooth. I was able to demo both the example The MathWorks provide and my enhanced version, but since the lighting was spotty, I was only able to do it once. (It was very sensitive to people walking by and casting shadows from the overhead lights.)
I also brought a long a few EV3 bots. I had a couple of ‘kit’ bots that were built with the instructions (EV3RSTORM and a robotic arm), but I also decided to make my own flyer stuffing robot. I will save the details of that bot for another post as well, but it is safe to say it was a hit with every one in attendance. You can see it right on the corner of the table in the picture below.
Below are a few more pics from the display. Everyone really seemed to like the interactive display. Other members of my LUG had displays that ranged from a trick or treating street, motorized technic models, and a BrickPi. We really had a nice showing and attracted a ton of attention.
I look forward to the next event, although I might need to scale it back a bit. 15 bots was crazy! Plus, I wasnt able to bring a few of my other projects. Stay tuned for more updates. I have quite a backlog and I hope to be updating them soon!
