In robotics an end effector is the device at the end of a robotic arm designed to interact with the environment.

The end effector on the space shuttle’s robotic arm uses a pattern of wires which closes like the aperture of a camera around a handle or other grasping point.

In the Discovery Lab we learned about robotics in space, such as Robonaut and Canadarm. We watched video clips (see links below), read and discussed an article about the robotic arm on the Space Shuttle and International Space Station, and made end effector models to pick up bottles and other items around the room.
