A robot walks on water thanks to evolution’s solution

Summary

The article discusses a new robot, Rhagobot, inspired by water striders, that can walk on water due to its unique leg design. The robot's design allows for efficient movement and potential applications in environmental monitoring and search and rescue.

Key Takeaways

1. Rhagobot, inspired by water striders, uses fan-like appendages on its middle legs to glide across water.
2. The robot's leg fans passively open and close based on water movement, eliminating the need for an extra power source.
3. Rhagobot has potential applications in environmental monitoring, search and rescue missions, and even exploring extraterrestrial environments.
