Patent attributes
A charging system incorporates at least one motor; conductive charging arms rotatably coupled to the motor; a controller coupled to the motor and configured to rotate the conductive charging arms; and a sensor configured to sense the presence of a powered device and provide a signal to notify the controller of the presence of the powered device. In response to receiving the signal, the controller controls the motor to rotate the conductive arms to positions of electrical charging contact with the powered device. The powered device can be a drone powered by a rechargeable battery. The positions of electrical charging contact include electrical connections to terminals of the rechargeable battery. The charging system may also incorporate the feature of the motor having a stepper motor coupled to each of the conductive arms.
