Underwater Robots

Student Activity:

Simple Machines: Robot Building Blocks

Grade Level:

6th - 8th grade (Physical Science/Engineering)

Activity Description:

Students practice the engineering design process to develop a working manipulator arm for a Remotely Operated Vehicle (ROV). Through the design process, students explore how simple machines are combined and used to develop complex systems, like manipulator arms. Students also develop a hydraulic actuator, to convert energy into motion for their designs.
