0x00
Builder: Jamie GorrThis is my first 'bot, built completely with stock parts. This photo is with no sensors attached but became a line follower when complete. This was my introduction into robots and C programming for microcontrollers.
It did complete the line following challenge, however, it was s-l-o-w. It came in 9th out of 13 (the rest DNF). One reason is that the twin gearbox I used has limited gear ratios and must be configured such that the drive axle utilizes the "C" hole which results in a very low gear ratio. Never-the-less, I was happy to have something to enter and complete the course.
It was the first time being exposed to AVR, and I only have a (very) limited knowledge of PICs. This robot was built, start to finish, programming and everything, in one month.
Since then, I took the 'bot completely apart to reclaim parts for a new 'bot. However, after looking at the gear-box a little closer, I realized there was another way to work the gears while still keeping the axles in the "C" hole to allow proper fit of the tires in the chassis.. So I rebuilt it, adding a switch and new wiring. Now I got something better (faster) to work and compete with. :-)
I have "renamed" the new 'bot 0x00 for lack of a creative name.
Very first iteration of 0x00. Notice the ghetto wire-tie holding the battery pack down.
Here is the "new" and improved 'bot. Notice the addition of a switch to cut power to the controller and the nice Velcro strap holing the battery pack down. Also, all the wiring is routed underneath of the platform making a nice, neat appearance.
Here is a close up of the re-worked gearbox. The final gear ratio is: (38/8)(42/12) = 16.625:1.
