Design a Parachute
Source Institutions
After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.
We Have Capture!
Source Institutions
Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.
