Abstract

See full text

Systems and methods relating to a clutch system for use in controllably transmitting torque from an input shaft to an output shaft. The clutch system has a torque transmission fluid that has a viscosity that changes based on the strength of an electromagnetic field passing through the fluid. A number of sensors are placed at different radial locations on the torque transmission disks to detect the strength of the electromagnetic field. Based on the strength of the electromagnetic field, the amount of torque being transmitted from the input shaft to the output shaft can be adjusted. Also disclosed is a distributed actuation architecture that uses this clutch system. The distributed actuation architecture allows for the use of a single drive motor in conjunction with multiple instances of the clutch system to actuate a mechanical linkage, such as a robotic arm.
