Careers in Engineering and Robotics require a high level of competency in math, science, reading and writing. A design process most used by engineering students includes defining a problem, brainstorming, researching, identifying requirements, exploring possibilities, selecting an approach, developing a design proposal, making a model or prototype, testing, refining, making and communicating results. Students conduct research to develop their knowledge base, stimulate creative ideas, and make informed decisions. Designers use an engineer's notebook to chronologically document all aspects of a design project, create sketches to quickly record, communicate and investigate ideas, and apply dimensions to drawings to communicate size information. Students also will develop models to communicate and evaluate possible solutions, and create mathematical formulas to establish geometric and functional relationships within their designs.
