About Our Robot

Number of Sensors: 1
Drivetrain: Direct, 2
Number of Attachments: 5
Programming Language Used: NXT
Number of Programs: 6
Most Consistently completed Mission:  Collect Corn
Strategy
How we chose our missions and their order:  First we picked three strategies: a) based on areas of the board b) multiple task in a run (i.e. all viruses together) c) multiple strategies a run with divided baskets since viruses on different sides.  We decided on c, but at our first scrimmage we couldn’t go to the table because we had no finished missions.  We had 1 program that was supposed to accomplish 4 missions at once, but it was so complicated we never completed it.  So we started over and just picked easy missions we thought we could finish.  We now have five finished missions. 
Favorite Mission and why:
The balls because they were easy and the corn because we were able to do it closely and consistently.
Design Process
We tried multiple design robot, but none of them worked very well.  We tried a 4 wheel design, but the wheels skidded when turning. We tried a robot with tank wheels, but it also didn’t have very good turning.  We tried a couple others but they were too complicated.  Eventually we thought we were spending too much time trying to come up with an idea and we just needed to get to actually programing, so we stuck with a basic design that works. We would prefer not use sensors, because they are inconsistent in competition.  However, without a sensor, it isn't really a robot.  So we have used one sensor in order to find the wall for our program to touch the back wall at the end of the match.
Innovation
Features that are different or cool:  Our coolest features are our attachments.  Our coolest attachment is our basket used to collect viruses.  At the moment, we have not seen another group use anything like it.Our attachment to pick up the truck is also very cool, but we cannot claim credit for the idea.
Mechanical Design:
Our robot has a basic three-wheeled design with two drive wheels and a free wheel to ease steering.  The robot has two drive motors and a third motor for accessories.We have not implemented use of additional sensors but have created attachments to perform specific mission tasks.We hope this aids your understanding of our team.  Thank you for volunteering your time to make this activity fun and rewarding.
