Scan Bot Program 1
This was the first program that we used. It worked well but we modified it to work better and have less passes over the letter.
Scan Bot Program 2
This is the second program that we used. This one was more succesful than the first because the bot only went over the letter once.

This is a picture of our succesful scan bot.
Final Secret Scan
This is the scan that Mr. Croke did. We believe that he scanned a M.
Reflection Questions
Our assignment was to create a bot that would scan printed letters on a piece of paper. After scanning three different letters we were to have Mr. Croke scan a letter that we did not know. Then by taking the graphs from the first three letters we were to figure out which letter Mr. Croke scanned. To begin this bot we had to come up with a design that would have the light censor pointing at the ground so the bot could scan the letter. We decided to build our own original bot and not look up any ideas from the internet or around class. First we started out by making a bot with all four tires level to each other so that the light censor could read the letters correctly. Then we had to modify the bot because the back was to heavy for the front so we added more weight to the front with extra tires and the light censor. Then we first porgrammed the bot tho pass of the letter three times. This program didnot work well, so we changed it to only pass over the letter once. When we finished building the bot we were ready to scan some letters. We scanned the letters K, M,and F. We then uploaded the graphs from the bot to the computer and saved them. Then we studied what each grapgh looked like so it would be easier to identify the mystery scan done by Mr. Croke. After that was done we were able to identify the mystery letter as M. Some of our class mates suggested that we only have the bot pass over the letter once instead of three times. After changing this our bot was very succesful.
