#Make a Robot Hand

To make a robot hand, get a piece of thin cardboard (about 6"x8" — a recycled cereal box works well) and Robot Hand Template.

Glue the template to the cardboard and cut on the dotted lines. Then watch the video on the next slide to see how to put it all together.

After students experiment with the robot hand, we suggest a class discussion.

#Discussion & Video

The robot hand can't do everything your hand can do.

Ask your student to experiment and figure out what their fingers and hands can do that the robot fingers and hands can't. Ask them: If you wanted to make the robot hand more like your hand, what would you need to add to the robot hand?

Discuss this question as a class. After your discussion, watch this video to hear some of the differences the Mystery Science team noticed.

Activity Prep

Print Prep

During this interactive training, teachers will discover the mechanism by which their muscles control their bones to move their bodies. In the activity, Robot Finger, teachers construct a model of a human finger and observe how pulling on a string (a model for tendons) causes it to bend at the joints.
