Step 5The Crawler
This one was inspired by many web pages I saw on the Internet. I found some of these small DC motors in old CD-ROM drives. They where used to open the CD-slot. I had two of the same type and need to use them here ...
The construction is rather easy. I used a thick copper wire that is used for the power in houses. I removed the insulation and build a T using two pieces. On one piece I soldered the small motors. The motors got short pieces of the insulation that gives them a better grip.
Now I took a 3V lithium battery and removed the plastic. I mounted the "naked" battery onto backbone of the crawler. To fix it I used paperclips, the ones that are coated with copper, so I could solder them to the backbone. The motors need to be connected so that they turn in different directions. I added a small switch and soldered the wires directly onto the battery.
Watch the video to find out how good this works.
He moves fast and he looks to the front and to the back simultaneously, isn't that scary? ;-)
