Water Walker
A miniature water strider robot

Goal: To develop a microrobot that can maneuver on water with power efficiency and agility.

Approach: To understand the physics of water striders to model their characteristics of floating on the surface of water. We are using micro-actuators to simulate water striders’ movements. We are also investigating different materials to improve the robot’s ability to float on water.

Benefits: Water strider robots will be small and relatively efficient. Because it is on the surface of water and light, the robot will be highly agile and can reach inaccessible areas for many different applications.
