Why did we choose this?
We (Jack and Ian) decided to work on NXT robots that work well for daily functions and fun activities. We also had a good prior knowledge of how to use NXT robots from a previous unit and we wanted to take basic skills and try to evolve them into a better skill set. We also both have fun with making new things. The robots we wanted to make were an automatic card-shuffler and a rubber band crossbow. We hoped we would finish both by the end of the project.
Project presentation outline:
We will be presenting what we did over this make project. We will be reporting what we have done over this unit, including how we spent our time, when we did team meetings, documentation, and changed in our progress. We will also be showing you pictures and videos of what we have built and some research we have done. We will also include feedback we have been given on this project.
Team members effort
Trials / Experiments
Any changes In process
To plan for this project we used Google Calendars. Before we began the work of this project (researching and building) we had a plan set up. This plan included a description of what we were going to do everyday. We hoped we would be able to keep up with this plan.
Every we week we tried to talk to each other about our teamwork for the past week and what we plan to do the current week. This helped our group members stay working well and make sure that someone is not doing all of the work. They worked effectively the first few weeks but the last few they were not as effectively probably because it was getting to the end of school.
Every once in a while we would switch roles in our team so that we both would be able to learn new things. Sometimes Ian would be a builder and sometimes Jack would document.
Both of us worked very well together. We were able to finish a lot of the crossbow but took it apart because we decided we would rather do the card-shuffler. When we worked on that we finished it very fast as well. Our main roles were:
Ian: Documenter and CO-Builder and Communications, Jack: Builder and CO-Documenter and Project Manager
Lego NXT Book
We both put a lot of effort into this project. During our first robot we attempted Jack put in most of the effort because he had done one before. Ian put effort in the card shuffler because he thought it would be a cool idea. We both put effort into building the robots but Ian put more effort into documenting.
We mainly did not research for this project. We have been doing this project and building by trail and error. Sometimes we used the NXT book to help us with parts for our designs. For example, the gears we used in the card shuffler were the same ones in the original taskbot design with some changes.
So for trails and experiments we first we tried to make a rubber band crossbow, but we failed to make it robotic, but we still made a working crossbow. After that we started working on the card shuffler, and finished it in 6 days, but it does not work as well as we hoped it to be. It ended up just tossing the cards around, so we made a rig to prevent the cards from going everywhere.
Work Effort: Overall we have almost met our expectations on this project. We had a working crossbow although it was unrobotic, and we had a working card-shuffler.
Teamwork: We had good teamwork throughout this project. Both of us tried to work on all the jobs for this assignment.
Improvement: We have improved a in some skills when we did this project. We started with a 12 out of 40 and then the next week we got a 40 out of 40. We had improvement in teamwork, effort, and following the directions given to us.
What we made: Currently, with us is the card-shuffler. We finished it but it is not as great as we hoped. It works, but it scatters cards everywhere instead of organizing the shuffled cards in a neat pile.
