Make a Snare Type End Effector

In this activity we make a model of the snare-type end effector on the robotic arm of the International Space Station. The arm's official name is Space Station Remote Manipulator System
Prep Time20 mins

Materials

  • 1 piece Card stock
  • 3 thin Rubber bands
  • Tape
  • Marker
  • Stapler
  • 1 Empty cardboard roll
  • Scissors
  • Small, lightweight items such as a pencil, bottle cap, paper clip.

Instructions

  • Gather the materials listed above.
