Abstract: A parallel eccentric electro-mechanical actuator provides motive power and includes an electric prime mover that drives the reducer's pinion gear. This pinion drives minimum three star gears with stationary shaft bearings. Each shaft contains an eccentric which are completely in parallel with each other. These eccentrics can be thought of as parallel/in-phase driven crankshafts. Each eccentric drives the parallel eccentric (PE) gear through a bearing. The PE gear exhibits a circular motion (without rotation) which in itself is unbalanced. The crankshafts have another eccentric which create an opposite inertia force to balance that of the PE gear. The PE gear contains an external toothed gear on its periphery. It meshes with the internal teeth of the output ring gear. The relative motion between the PE gear and the ring gear is that the PE gear rolls inside the ring gear. This relative motion is called hypo-cycloidal motion.

Abstract: A four level fault tolerant architecture for the intelligent machine system is based on the basic component of a self contained actuator module with standardized interfaces. This system architecture organizes all of the operational software to make it universal, high performing, fault tolerant, and use condition-based maintenance. The independent structural layers are structured and prioritized by the advanced electronic controllers. The sensor module creates an accurate parametric representation of the electro-mechanical actuator, and manages all resources in the electro-mechanical actuator. The system will also comprise of operational criteria, maximum performance envelopes, condition-based maintenance, fault tolerance, layered control, and force/motion control. The system allows independent development of different components of the framework, categorized into three levels: the management level, the servo control level, and the senor and communication level. The present disclosure establishes a fully responsive actuator whose intelligence manages a sufficiently broad set of choices.

In one embodiment, the invention offers a velocity summing arrangement with a differential gear between two prime movers driving a cage, which then drives a linear spindle screw transmission. Other embodiments feature two prime movers driving separate linear spindle screw transmissions, one internal and one external, in a totally concentric and compact integrated module.

Abstract: An actuator module for inducing the relative motion of robot members joined in a robot joint includes a Ferguson epicyclic gear train, integral motor and integrated control means. The gear train comprises a plurality of base gears connected to the robot members and a plurality of planet gear carriers, each planet gear carrier having a plurality of planet gears rotatably mounted therein. A motor integrated with certain gear train components induces the rotation of the planet gear carriers about or within the base gears. Because of the Ferguson paradox, this induces the motion of base gears connected to one robot member relative to those connected to the other robot member, which in turn causes the relative motion of the robot members. The actuator module can be configured as dual substantially symmetric systems and may comprise multiple stages of epicyclic gearing.
