In this challenge, students must program a rover to get from point A to point B on a map without driving across any of the craters located between the two points. Students will: Understand ratio concepts and use rate reasoning to solve real-world problems. Create an engineered model, limited by criteria and constraints, designed to achieve the task of solving a complex problem.
