4/5/09- Today we got our proposal accepted. We made our materials list and team roles. Materials: 2 pieces of 2*4, 2 pieces of 1*4, 1dolly rod, fishing line, ½ pound weight, piece of leather and knex wheels, and 2 long knex rods and a mousetrap Team Roles: Malcolm: Project Manager Kevin: Materials Manager Shounak: Communication Manager Nick: Lead Builder And here is a sketch of our project-

4/6/09- Today we completely decided on our project. We changed it from being made of wood to being made of knex. We decided on knex because we will not need to use any tools like hammers or nails or anything like that. We plan to buy a kit between 400 and 2000 pice kits. Although that is a very large window we could change the size of the project according to the size of the kit. A 400 pice kit costs about $20 and a 2000 pice kit costs about $45. THat is what we plan to do with our project. 4/11/09- Today we finally got are propsal apporved. We are going to make NXT bot that will sense if something is close to it. We check to make sure we had everything. We also started building are NXT. Are main problem is we can't make a good base. Malcolm came up with a good idea that we decide to make it. It is good beside the fact the front drags.

4-12-09 Today we finished building our robot. We had some problems with building it. When we started it, it went fine, then when it stop, it flipped over. So we changed the robot so we have some support before it tips over.

4-13-09 Today in engage we learned a lot about what we need to do to make our project work. We figured out that we need to prop the sensor up higher because before it was sensing the ground or the motor and would stop the bot.



5/15/09 We worked on finishing our bot it is now finished and we met our goal of finishing the bot by the end of the week. We learned that when we work on sepetate projects we get more done instead of all working on the same thing, 2 poeple work on the bot, one person programming, and the person who needs to document, helps programming, then with about 20 min in class does docunemtation. 5/18/09 Today we worked on our programming. We were just testing some of the sensors, so we would know how to use the sensors for our project. We used the ultra-sonic sensor to test out. We made a program that makes the robot go through a crowded are. it goes forrward until it finds something close to it, and then it goes back, and then goes forward again. We tested it by running the robot and then getting in the way of it, this made it stop for one second, then go forward again.



5-19-09 Today we had a couple problems. One was that we found out, that for our robot to turn we needed at least 2 motors, so we rebuilt our robot and made a couple little changes to have our robot have 2 motors. So now our robot turns. We also made a new program after we fixed that motors. We had that same program as before, which is having it go, sense something, so backward, and then going forward again, but we changed so it goes backward, then turns and goes forward again.



5-26-09- Today our robot broke while we were running it. It went under some red boxes, and it just broke in half. So today we fixed our robot, and now it is back to normal. We also made a basket attached to our robot. Now we can start making our program for delivering messages. It is very sterdy because when we droped it on the floor it did not break. The first time we dropped it it broke, but the second time it stayed toghether. That is what we did today.

Today in engage we tested to make sure that the basket worked. We put in the rubber band holders that come in the NXT kit and ran the program. THe basket works on the NXT. Our goal now for the final project is that the bot can have a note put in it's basket and run successfully. We learned today that considering every option can be successful. We didn't think that the basket idea was a good idea at first but when we tried it the basket was a success. We used legos to create the basket that is on our project.

6-2-09 Today our group decided to totally destroy our robot and rebuild it (Without asking Malcolm). We wanted to rebuild because we wanted a stronger base. It took us awhile but we finished when we wanted, to today. We really didn’t change much, we just put supports where they were needed and it made the robot much strong. Our goal this week is to finish our project so we don't fail the project.

We had some problems with our robot getting it more durable but we persevered and made our robot nice and strong. Our goal for the final project was to not only have a robot that could manuever through a crowded area without getting crushed but to make a robot that could also carry a note into another room for another person to recieve. I think that our group did a good job on getting our work done but i think that we could have worked a little more dilegently and efficently. But over all i think our group did a good job on the end project and the process.
