摘要： Systems and methods relate to a vertical takeoff and landing (VTOL) platform that can include a stator and a rotor magnetically levitated by the stator. The rotor and stator can be annular, such that the rotor rotates about a rotational axis. The stator can include magnets that provide guidance, levitation, and drive forces to drive the rotor, as well as to control operation of rotor blades of the rotor that can be independently rotated to specific pitch angles to control at least one of lift, pitch, roll, or yaw of the VTOL platform. Various controllers can be used to enable independent and redundant control of components of the VTOL platform.

摘要： A robot device includes a first link and a second link coupled to the first link via an elbow. One or more of the first link or the second link rotates about an axis of the elbow. The robot device further includes a generator disposed in the elbow. The generator is configured to generate electrical power based on relative angular mechanical movement associated with the elbow. The robot device further includes an end effector configured to transport a substrate within a substrate processing system. The end effector is disposed at a distal end of the second link. The end effector is to receive the electrical power generated by the generator.
