A feed mechanism that advances fabric comprises at least one dog that mechanically advances the fabric toward a sewing head and at least one actuator that is coupled to and actuates the at least one dog in a servo controlled motion so that the sewing head sews the fabric at a desirable position.

A representative machine comprises a non-rigid robotic device having a tool head; and a rigid inertial stiffening system that is part of a tool head and includes a mass to provide precise position of the tool head. The rigid inertial stiffening system achieves high positional precision of the tool head, in the face of large disturbing forces by locally accelerating the mass to counter the disturbing forces.

A conveyance system that transports fabric comprises a work space having a surface that the fabric can be transports across, and at least one budger that moves and/or provide force to the fabric in a servo controlled motion.

Embodiments of the present invention provide a system and device for making garment. One embodiment, for example, includes a system that comprises a processing device and a sewing module that sews garment material to facilitate making the garment. The system further comprises memory that includes a thread count manager having instructions stored in the memory. The instructions are executed by the processing device and include logic configured to instruct the sewing module to sew the garment material based on counting threads of the garment material rather than using the geometric shape of pieces of garment material.

Disclosed are algorithms for controlling multiple states of a dynamic system, such as controlling positioning and cable sway in cranes. Exemplary apparatus and methods may be implemented using first and second serially coupled feedback loops coupled to a plant and payload that are to be controlled. The first feedback loop comprises a first control module. It generates a filtered actuator command from an error signal derived from a signal representing a desired system state and a feedback signal indicative of the actual system state. The generated signal is operative to position the payload. The second feedback loop comprises a second control module that generates a second actuator command that is operative to cause the plant to have an output of zero, to eliminate disturbance-induced oscillations. Input shaping may be employed in the first loop for eliminating motion-induced oscillations. The first control module is used for precise payload positioning, and the second control module is used to reject disturbance-induced oscillations. A model reference loop may be employed that outputs a modeled response that is an estimate of the response of the plant in the absence of external disturbances, and which may be used to generate a second actuator command for causing the plant to follow the modeled response.

A bed making apparatus can lift, push, and pull the bedding layer by layer so as to manipulate bedding originally disorganized to a made up state. The apparatus includes a vision device that evaluates and detects the current state of the bedding sensors and a computing device that determines the process of the making the bed. Typically, a robotic arm or roving device traverses the surface of the bed and can be attached to the headboard of the bed.

An apparatus which allows one to maintain precision placement of a manipulator which undergoes repeated controlled motions or trajectories is provided. The structure of the apparatus is compliant such that the manipulator may be displaced by forces applied to the mechanical structure. This compliance is due to a lack of precision in the fabrication of the component parts of the machine, and to a lack of rigidity due to a lightweight design. This displacement is of a greater magnitude than the precision positioning tolerance of the apparatus. Consequently, the manipulator may then be displaced outside of the positioning tolerance due to applied forces. However, it is a characteristic of the present invention, that despite the compliance of the mechanical structure of the apparatus, the positioning tolerance will be maintained. The controlled motion is accomplished by the generation of control signals by computer software running on a computer control system. The control software enables the system to run at much greater speeds while not exciting unwanted movement or vibration in the compliant mechanical structure.

An image reading system observes a field of view and forms electrical signals indicating the presence of objects within the field as to location and movement. After ascertaining the area of the field in which an object is located, the system is speeded up by reading signals outside the area at a high rate of speed and those inside the area at a normal rate of speed.
