2. MIT creates gentle robot that works using water
Massachusetts Institute of Technology engineers have created a robot that is made of hydrogels and powered by water. The robot has the potential to be used in surgical applications.
Tough, rubbery and mostly water, these robots can perform an array of tasks including kicking a ball or grabbing and releasing live fish.
The transparent robots move by having water pump in and out of them. They consist of an assortment of hollow, hydrogel structures that are connected to rubber tubes. When the robots fill with water, the hydrogel structures inflate, and the robot can bend and stretch.
