While we did have a gripper design in the submitted proposal, we wanted the undergraduates in the course to try their hand at designing grippers. The course largely consists of Computer Science majors, with a few students who are majoring in Electrical and Computer Engineering and one student majoring in Mechanical Engineering. To make the task more approachable, students were told to use found or recycled materials for their grippers. Fortunately for everyone, the lab we work in has a wide range of random materials that can be used.
We recorded video of everyone's demonstrations and edited them together:
Hope you enjoy the movie.
