Pliant Energy Systems showcases C-Ray amphibious bionic robot designed for stealthy scouting
A video credited to Pliant Energy Systems shows the company's amphibious bionic robot, C-Ray, moving across an icy surface with an action camera mounted on its back. The company describes C-Ray as designed for scouting, quiet operation, low power use, and high stealth. According to a post about the robot, C-Ray was developed by the Brooklyn-based company with U.S. Navy research funding and uses flexible undulating fins inspired by animal movement instead of conventional propellers, allowing the roughly 1-meter robot to transition between water, beaches, sand, snow, and solid ground.

This thing can SWIM like a ray, crawl across land and ice, slither through difficult terrain, and do it all while trying to stay almost invisible. Meet C-Ray, an amphibious bionic robot developed by Brooklyn-based Pliant Energy Systems with U.S. Navy research funding. Instead of conventional propellers, it uses flexible undulating FINS inspired by animal movement, allowing the roughly 1-meter (3.3-foot) robot to transition between water, beaches, sand, snow and solid ground. The design is built around low power, low noise and minimal disturbance, making it especially interesting for STEALTH reconnaissance. Writer: Sol https://t.co/QkisQtAuou
