Scan Bot
Our first prototype was constructed with one arm that moved back and forth and wheels that moved the robot up and down. making it able to detect and x and y axis. Some problems was thaty the arm wasnt long enough and it was a little weak in the middle and the Nxt fell of regulary.
SCAN BOT II
The design is based off of a scanner. I thought of it after remembering about reading about some of the 3D scanners made with NXTs on Engadget. Although it did take a slightley differnt form from what i had planned. It was to be stationary and to have the arm with the light sensor move. It ended up moving the entire bot.
Other than the problems with the arm tipping due to a weight in-balance. Other than that the entire design worked well and we correctley guessed what croke scanned.

The letter Croke scanned was "F" !
Reflection.
The purpose of this project is to bulid a robot that could scan a sheet of paper, and from that scan tell what letter is on the sheet of paper.
To do this assignment i first started with a robot that that cound move a light sensor over every part of the letter. when i bulit my robot, I went straight into investagator, to see the graph/chart of every letter. then we had a collecetion of a bunch of letters as shown above. then Mr.croke scaned one random letter and we came to the conclusion that the letter was F.
Overall i felt the Scan Bot was a farly reasonable assignment. Nothhing to hard, but it really showed me how a scan really works in real life. i was a little skeptical if a robot could really scane a letter at first but then after doing all the test I realized that the Bot was a complete success.
What I learned fom the project is that, i learned how scans work. decoding letters in chart and then matching from a data base. also i learned how to bulid a scanner as shown in the picture above. If i were to bulid a scanner in real life i would know just how to build it and make improvenments with the knowdledge of this assignment.
If i could do something differently i would make a bigger scanner that would scan the entire letter more specisly and have more letter to scan rather then the five. all for to improve my data base and make a real scanner.
