Abstract
A carrier for controlling torque delivery to a payload includes a carrier component configured to rotate about a carrier axis, a payload support structure coupled to the carrier component and configured to support the payload, and a rotational device coupled to the payload support structure. The rotational device includes a non-rotating portion directly coupled to the payload support structure and a rotating portion configured to rotate freely to provide a supplemental torque to the payload support structure to compensate for a torque transmission delay from the carrier component to the payload support structure when the carrier component rotates about the carrier axis.
Claims9
A carrier for controlling torque delivery to a payload, comprising:
- a carrier component configured to rotate about a carrier axis;
- a payload support structure coupled to the carrier component and configured to support the payload;
- an actuator configured to generate a correction torque through the carrier component in response to and to correct for an external torque exerted onto the payload support structure;
- and
- a rotational device coupled to the payload support structure, comprising:
- a non-rotating portion directly coupled to the payload support structure;
- and
- a rotating portion configured to rotate freely to provide a supplemental torque to the payload support structure to compensate the correction torque for a torque transmission delay from the carrier component to the payload support structure when the carrier component rotates about the carrier axis, wherein the supplemental torque counteracts the external torque at the payload support structure before the correction torque reaches the payload support structure, and the supplemental torque is applied in a same direction as the correction torque.
