Lesson Focus Develop a robot arm using common materials. Students will explore design, construction, teamwork, and materials selection and use.
Lesson Synopsis
Participating teams of three or four students are provided with a bag including the materials listed below. Each team must use the materials to design and build a working robot arm. The robot arm must be at least 18 inches in length and be able to pick up an empty Styrofoam cup. Teams of students must agree on a design for the robot arm and identify what materials will be used. Students will draw a sketch of their agreed upon design prior to construction. Resulting robot arms are then tested and checked for range of motion and satisfaction of the given criteria.
Age Levels: 8-18
Objectives
