Scientists at the Max Planck Institute developed hexagon-shaped robotic components that can be snapped together into high-speed robots with rearrangeable capabilities. The modules feature artificial muscles and magnets for quick connections, enabling rapid changes in geometry and motion.
Researchers at NC State University have developed a technique to create miniature soft hydraulic actuators that can move small soft robots, allowing for exceptional control and delicacy. The actuators use shape memory polymers and microfluidic channels to control the motion and shape change of the soft robots.
The new metafluid can transition between Newtonian and non-Newtonian states, allowing for programmable viscosity and compressibility. The researchers demonstrated the fluid's capabilities in a hydraulic robotic gripper, picking up objects of varying weights without crushing them.
Researchers developed electrically-driven soft valves to control hydraulic soft actuators, enabling faster and more powerful control of macro- and small-scale hydraulic actuators. The breakthrough allows for unprecedented motion control of soft robots with internal volume ranging from hundreds of microliters to tens of milliliters.
