Purchase extra cosmic claw kits to use with your Galactic Quest STEM Challenge kit or to use as a stand alone activity.  In this activity, youth will use the Engineering Design Process to design, build, and operate a robotic claw. Working together, the group will create a model of a hydraulic-powered robotic arm and claw and test it by completing an agricultural task. Ultimately, the mechanical claw should be able to perform a simple grasping, scooping, or raking action to cultivate crops on another world.
