Gruber is currently working on a related project. Since 2015, Gruber has worked in collaboration with the Harvard MicroRobotics Laboratory in the development of several gentle robotic devices that allow marine researchers to capture and analyze jellyfish and other delicate sea creatures without causing harm. Working with Robert Wood, the director of the MicroRobotics Laboratory, they have developed Squishy Robot Fingers, the Origami Robot, teleoperated soft robotic arms for submarines, and an ultra-gentle robot with soft fingers. The work of the "Squishy Finger/Soft Robotics for Delicate Deep-sea Marine Biological Interactions Team" was highlighted in the American Museum of Natural History exhibit, "Unseen Oceans".
