A few weeks ago our school was told we were going to have a science fair so I went to work brain storming ideas. After a while I decided that I wanted to do something that had to do with robotics. Then I narrowed it down again and decided that I will explain how robots work. After that I started to work on the project but thought it would be boring to just have a poster and a few pictures of my past robots, so I made a small robot to go along with it.
When I started thinking of what kind of robot to build I knew it would have to have a few qualities. First, it would have to be a quick build since I only had about two weeks to work on it. Next, it would have to be made with only parts I had so I would not have to wait for shipping. After that, it would have to be an easy build but not so easy that I did not learn anything. Finally, I wanted this robot to interact with the people viewing my project.
With all this in mind I decided to make a hand tracking robot. First, I took a Dagu pan/tilt sensor mount of an old project and put a Dagu IR array sensor on it and wired it up to a picaxe 28x1. Then, once it was all together I put it in a tupper ware container for prototyping. Once I did that I started coding it, and this turned out to be the hardest part. After I finally got the code running alright I worked on the final enclosure with some help from my dad. The final enclosure was a little box with a pexi-glass slide in lid to show all the brains with the "head" mounted on the back. Also I put in an arcade button that you would have to push and hold to turn the robot on. I used the button so that once people moved away from it and let the button go it would turn off to save battery power.
Over all I think this project went nicely and looked good. Also I think I am really starting to get basic. Finally, I would like to thank everyone who helped me with my coding problem.
(I will post some video later when I can get someone to help me hold the camra)
P.S. I won 1st Place in the science fair.
