NXT Robot Challenge Introduction
NXT Mindstorms robot kits are self contained building tools that allows students to explore various aspects of engineering relatively quickly, easily and without any supplemental equipment other than a computer for programming. In this project students will involve working in teams to design and construct a Wii remote control pathfinder integrate a wirelesscamera and a Nintendo Wii remote with the LEGO robotics system.

Educational Goals
  

   

Provide students with hands on experience building a simple programmable robot. To demonstrate that design processes typically involve a multitude of skills and knowledge from many subject areas. Allow students to learn that in the real world there are not correct or incorrect solutions but onesthat work well, others that don't work well, and many that don't work at all. Students will be able to see that several different solutions may work equally well. To familiarize students with the design process- from brainstorming, initial design, prototyping, testing, revising, to final production and competition. To allow students to experience the perilous designer/builder interface. To sparkstudent’s interest in Science and Technology. To win some Money ($100 winners take all)

Competition Guidelines
The objective is to build a Wii remote controlled wireless remote camera assisted unmanned rover that can move across an obstacle course in the shortest time and able to pick up targets along the way with an onboard projectile.Students will control the rover from a remote location with a Wii remote while the robot roams around the obstacle course, relaying sorely on what it sees from the video camera. With the new version NXTcamera, rover will control itself and become completely autonomous. The pathfinder must be designed with proper gear ratio and traction so that it is able to climb ramp, cross climb stairs, turncorner and free itself from a sandpit. In addition, the pathfinder needs to be able find targets to shoot to score points and able to open gates and move around autonomously without getting stuck. For a specific floor plan, please refer to the Playing Field section. The contest is also subject to a few ground rules. Please follow them carefully before begin your design.
Teams The team will consist ofthree or four members. Each member is responsible for a part of the design and construction. Great emphasis will be placed on teamwork. Evaluation of contribution from each team member will play a big part in the team’s final grade. Robot Size and Weight The maximum size of the Robot shall be 12" by 12" by 12 ". The Robot can not look over the walls of the structure and must never extend itselfbeyond 12 inches in any dimension. All Robots will be carefully measured. Don't let your Robot be disqualified because it is slightly over the limit. There are no restrictions on the weight of the Robot. The robot must have the comfort and look of a regular wheelchair. The robot also need to be able to support and hold a monchichi (will be provided) without losing it during the crossing. The robotmust be able to turn on the crossing light (the lamp) at the crosswalk to cross safely without getting hit by traffic. The robot must have three programs installed on the NXT. One must enable the robot to safely cross the obstacle course without losing its passenger. The second program is that the robot must move like a car on the street. It needs to able to move back and forth across a narrow...
