Carnegie Mellon's latest snakebot can swim underwater

Over the years, Carnegie Mellon University has upgraded its famous snakebot to give it the ability to do things like climb sand dunes and grasp objects. With its latest iteration, you can now add swimming to that list. Work on the Hardened Underwater Modular Robot Snake (HUMRS) started in July 2020. The university's robotics lab began by adapting water-resistant modules it had used in the past to allow the robot to operate in less than ideal conditions. They then added a series of turbines and thrusters so that it could move underwater.
