Control devices for end effectors with multi-axis roller wheels, systems including the same, and related methods

Abstract

End effectors and systems may capture, release, and/or create a mating engagement between the end effector and a target object, such as in capture and launch applications, grasping applications, or pick-and-place applications. The end effectors are tolerant of positional and rotational misalignment of the target object, and may include a plurality of roller wheels, one or more of which is arranged in a non-parallel plane with respect to one or more other roller wheels. Control devices enable operation of these and other end effectors in a portable, self-contained system that a single operator can use in a hand-held or wearable form factor. The control devices may include a drive system for power transfer, manual and automatic leveling or angular positioning mechanisms, and/or operator-mounting features. Related methods may involve capture and release, pick-and-place, and/or grasping operations performed with the disclosed control device and one or more end effectors coupled thereto.
