Abstract

A swivel assembly can have a longitudinal axis. The swivel assembly can have an upper portion and a lower portion that is rotationally coupled to the upper portion. The lower portion can have a connector configured to securely engage a cable. The lower portion can be configured to remain in electrical communication with the upper portion as the lower portion rotates with respect to the upper portion. A motor can be disposed between the upper portion and the lower portion and configured to selectively rotate the lower portion. A sensor can be configured to detect torsion in the cable. A controller can be in communication with the sensor and the motor. Upon receiving a signal from the sensor indicating a threshold torsion in the cable, the controller can be configured to cause the motor to rotate in a direction corresponding to a direction of the torsion in the cable.
