I decided to make my robot a model of R2D2. I went to my basement to salvage some trash and old junk which we no longer needed and as a result, the base of my robot is made of a flashlight and foam. The head is entirely foam, and all of the body is wrapped in super glue. I bought cardboard boxes for $0.44 each and constructed multiple legs and other useful parts. parts of its eyes are also the top of a pen cap and all of the blue shiny paper is origami paper from my drawers. All in all, it was a fun project, but there were some difficult parts which had to be overcome. One of which is putting the hummingbird inside caused wiring extremely difficult and next to impossible to see where what was going. Thats where tweezers come it! The next difficult issue, probably the hardest, was overcoming torque with R2D2's wheels. the motor does not have any sort of attachment process, so only glue could have been used. This caused the twisting to come off multiple times until i found the perfect ratio of hot glue and super glue. Finally, the last difficult issue was the fact that the arts and bots program was unable to load my MC Hammer "cant touch this" song. I had to troubleshoot it and work it through itunes instead. My original plan wanted it to pace back and forth, checking every second for an object, and when something would obstruct its view, it would dance. I instead had to put this at a predictable time since i, manually, had to click itunes. overall all, it was a fun and interesting project and i recommend it for any highschool kid.
