Abstract
A motion imparting leg for imparting an oscillating or reciprocating rectilinear motion to a rocking bed, comprising a base, an upper surface movable relative to the base for imparting the oscillating or reciprocating motion to the rocking bed, a servo motor for driving movement of the upper surface, a position sensor for determining the rotational position of the servo motor or the position of the upper surface, and a motor controller for controlling the servo motor based on data from the position sensing means.
Claims23
A motion imparting leg for imparting an oscillating or reciprocating rectilinear motion to a rocking bed, the motion imparting leg comprising:
- a base;
- an upper surface movable relative to the base for imparting oscillating or reciprocating motion;
- a servo motor for driving movement of the upper surface;
- a position sensor for determining a rotational position of the servo motor or a position of the upper surface;
- and
- a motor controller for controlling the servo motor based on data from the position sensor.
A method of calibrating a motion imparting leg, the method comprising:
- providing a motion imparting leg comprising an upper surface movable relative to a base through a motion path, an electric motor for driving movement of the upper surface through the motion path, a motor controller for controlling an electric motor and a positioning system connected to a motor controller;
- operating the electric motor to drive the upper surface through the motion path until the positioning system determines both ends of the motion path;
- and
- storing positional data related to the determined ends in the motor controller.
