Actually, the hot glue gun was the very first piece of hardware I have bought when I decided to make robots.
I followed the tutorial on wikiHow. The aluminum paper sheet was very useful to clean the nozzle.
My first try was not successful because I did not wait enough for the gun to heat. My gun has two temperature options (low and high), so I used the high position for this work.
I have cut and drilled holes in wooden sticks in order to hold the camera. After that, I glued everything together:
I have put the servo between two sticks in each side and screwed the sticks together. This way, the servo is properly fixed but it is not glued in the car.
