Researchers at the Max Planck Institute for Intelligent Systems in Germany have developed a robotic jellyfish that can swim, burrow, and transport objects.
The robot, about three millimeters in diameter, is made up of a central body and eight bendable flaps that can beat upwards and downwards in unison about 150 times per minute, which are extended by flippers that help propel the robot through the water.
Each of the flaps is made of silicone rubber embedded with magnetic microparticles of neodymium-iron-boron, so the researchers can steer the robot and change its behavior through the application of magnetic fields.
