WP_20131005_008This 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.)

WP_20131005_001I 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.

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.
