Cable Car
Source Institutions
In this activity, learners string a line across the room and build cable cars that can move from on end to the other.
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.
