While we were taking field trips to ArborGen, the Horticultural Department at Trident, and having the teleconference with Dr. Bohlmann, we worked on our robot.
There are four challenges in First Lego League. The first is the research presentation. The second is the teamwork, where the team describes what they have done as a team. The third, the technical presentation, is where the team presents the judges with their robot and describes what it does. The fourth, and possibly the most important of the challenges, is the obstacle course at the tables. These obstacle courses change with the topic every season, giving the teams different and more challenging tasks their robot has to perform.
We started making the robot in August at the start of the season. Our coaches divided us up into teams of two, and the teams made their own robot. When all of the robots were finished, we tested the robots on the table. We then all voted on the robot that we thought performed the best.
Over time, we added and took off parts in order for the robot to run most efficiently and according to what our team wanted. Right now our robot has three motors, the maximum amount that is allowed, a touch sensor, and an NXT brick. This is always needed, being the brain of the robot. We only have two wheels on our robot, and they are at the "front" of it. We have j-hooks on the back, because we wanted the least amount of traction in the back so that it could turn more easily. If we used plain wheels, the rubber would create friction and our robot would not be able to turn at all. At the beginning of the year, we expected our robot to be doing a lot of lifting. We decided that the motor needed to be higher than usual so that it could lift things more easily. We made the robot so that the motor is at a forty-five degree angle so it can lift things and drop them over a wall.

About Us
- Ice Wolves 122
- We are a First Lego League team out of Charleston, South Carolina. The team consists of Anna, Mattie, Skyler, Shea, Hal, Liam and our coaches Ms. Stephanie and Mr. Sam. Our challenge is to make climate connections between our geographical region and another area in the world which is experiencing similar issues. We are researching the Southern Pine Beetle and it's impact on forests throughout North America.

The Attachments:
Attachments help the robot preform tasks, such as grabbing, pushing, or pulling. We have two attachments on our robot this year. One is a net in the shape of a semi-circle. We use this attachment to capture items on the board and take them places. Our other attachment is a fork with prongs. We use this attachment to spear items, to sweep items, and to carry items.
The tires on the robots are slippery so its going to stink on the mat at the tournament, literally because our mat is scuffed with rubber burns.
