Abstract:
1. A system for transferring a body from a first surface to a second surface, comprising: a frame configured to support a body; a bottom translation mechanism disposed at the bottom portion of the frame and configured to engage the first surface and the second surface and to translate the system back and forth between the second surface and the first surface, the bottom translation mechanism comprising at least two belts independently controlled by at least two respective internal drive motors; a top translation mechanism disposed at the top portion of the frame and configured to burrow the system between the first surface and the body as the bottom translation mechanism transfers the system from the second surface to the first surface; and a yaw control system within the frame and comprising at least one yaw sensor operatively coupled to the at least two drive motors of the bottom translation mechanism to form a closed-loop feedback system configured to continuously sense non-straight motion of the frame and responsively and independently adjust the speed of the at least two drive motors to achieve a straight path as the system for transferring a body moves between the first and second surfaces.
