End Effectors in Battle Creek MI!

A Robotic Arm

7th graders at Northwestern Middle School learned about the importance of robotics aboard the ISS. Many students tried their hand at picking up a ping pong ball and eraser with chopsticks and all agreed a more sound mechanical hand was needed to grapple objects in space. Mission question: Can we design a robotic hand to grab objects that won't slip out of grasp? We watched the Mission X video explaining the end effector and proceeded to make our own with Styrofoam cups and string. Students reported in their journals what strategies they used and whether they needed to redesign their efforts.
