In VEX IQ, the optimum size for a team is 3 - 4 students. This allows for all members of the team to participate in designing, building, driving and coding the robot. In a VEX IQ team, members switch roles often. One idea could be to have team members take on roles such as:
Engineer: Construct the robot
Computer Scientist: Program the joystick and the robot for the Autonomous Robot Skills Challenge.
Documentarian: Record and document the engineering design process, programming, and game strategies using text, diagrams, sketches, and printed images.
