Time to break into the video camera. Today’s robot uses de-soldered components from the video camcorder.
So far, the robots have been quite small; Boba (day 1) being the tallest at 45mm. So for day 5, I wanted a robot taller and with a less electronic feel to it.
I was very pleased with the result however this robot took several stages of gluing which can be very impractical when you have only one day to build it. The main structure is metallic and thus heavy, so the robot was unable to support it’s own weight whilst gluing. Consequently, I had to re-glue it in several places in the following days. I originally used a cyanoacrylate-based, 2 part glue that had a low shear strength which is not ideal for inflexible metals with low surface contact between parts. Epoxy or screws are definitely the way to go for fixing metals.
Today I couldn’t resist. I had the head piece more-or-less from the twin light sensor mount on the video camera. I had hoped to build in a PCB to make the robot look ‘roboty’ but within my one day slot, getting the chassis to work took up too much time. Managing the build progress ad-hoc is all part of the challenge and the fun. Plus, he still looks cool!
