Understanding Mosquitoes Key to Aquatic Robots

March 3, 2015 3:00 pm | by AIP Publishing | News | Comments

Small semi-aqueous arthropods, such as mosquitoes and water striders, are free to go about their waterborne business. By examining the forces that the segments of mosquito legs generate against a water surface, researchers have unraveled the mechanical logic that allows the mosquitoes to walk on water, which may help in the design of biomimetic structures, such as aquatic robots and small boats.
