Document Type and Number:
WIPO Patent Application WO/2017/041302
Kind Code:
A1
Abstract:
An apparatus and methods for stabilizing a payload device such as an imaging device are provided. The apparatus includes a carrier for controlling torque delivery to a payload (1804). The carrier comprises at least one carrier component (L1, L2, L3) configured for rotation about a carrier axis;a payload support structure (102) coupled to the carrier component (L1, L2, L3),wherein the payload support structure (102) is configured to support the payload (1804);and at least one rotational device (RW, RW1, RW2, RW3) coupled to the payload support structure (102); the rotational device (RW, RW1, RW2, RW3) comprise a non-rotating portion directly coupled to the payload support structure (102) and a rotating portion configured to rotate freely to provide a supplemental torque to the payload support structure (102). The supplemental torque (Ts_z, Ts_x, Ts_y) is provided to compensate for a torque transmission delay (d(z)) from the carrier component (L1, L2, L3) to the payload support structure (102) when the carrier component( L1, L2, L3) rotates about the carrier axis.
