Article Manipulator Moves Analogous With Human Hand, Finger, Or Arm Movement Patents (Class 414/1)
  • Publication number: 20110129320
    Abstract: A robotic system includes a robot for moving a payload in response to a calculated input force. Sensors in respective sensor housings are connected to a handle, each sensor including a light emitter and receiver. The sensors measure a light beam received by a respective receiver. A controller calculates the calculated input force using received light. Each sensor housing modifies an interruption of the light beam in a sensor when the actual input force is applied, and the controller controls the robot using the calculated input force. A method of controlling the robot includes emitting the light beam, flexing a portion of the sensor housing(s) using the actual input force to interrupt the light beam, and using a host machine to calculate the calculated input force as a function of the portion of the light beam received by the light receiver. The robot is controlled using the calculated input force.

  • Patent number: 7865266
    Abstract: Improved robotic surgical systems, devices, and methods include selectably associatable master/slave pairs, often having more manipulator arms than will be moved simultaneously by the two hands of a surgeon. Four manipulator arms can support an image capture device, a left hand tissue manipulation tool, a right hand tissue manipulation tool, and a fourth surgical instrument, particularly for stabilizing, retracting, tool change, or other functions benefiting from intermittent movement. The four or more arms may sequentially be controlled by left and right master input control devices. The fourth arm may be used to support another image capture device, and control of some or all of the arms may be transferred back-and-forth between the operator and an assistant. Two or more robotic systems each having master controls and slave manipulators may be coupled to enable cooperative surgery between two or more operators.

  • Patent number: 7765031
    Abstract: In a robot, a first determining unit determines whether there is an interference region in which a first occupation region and a second occupation region are at least partially overlapped with each other. A second determining determines whether a second movable part of another robot is at least partially located in the interference region based on an actual position of the second movable part. A stopping unit begins stopping, at a predetermined timing, movement of the first movable part if it is determined that there is the interference region, and that the second movable part is at least partially located in the interference region. The predetermined timing is determined based on a positional relationship between an actual position of the first movable part and the interference region.

    Abstract: A robot or the like able to precisely grip an object by flexibly changing an operation in accordance with various environments. When it is judged that a robot is in a “first state”, the action of the robot is controlled in accordance with a “first action mode”. Thus, the robot does not move and moves an arm or the like on the spot so that a first object W1 can be gripped by a hand. On the other hand, when the judging result is denial, the robot acts in an action mode different from the first action mode so that a relative position or the like of the first object W1 with the robot as a reference is changed. As a result, the robot can be changed from a non-first state to the first state.

Each robot is capable of receiving, processing, and acting on one or more multi-device primitive commands that describe a task the robot will perform in response to other robots and the external conditions. The commands facilitate a distributed command and control structure, relieving a central apparatus or operator from the need to monitor the progress of each robot. This virtually eliminates the corresponding constraint on the maximum number of robots that can be deployed to perform a task (e.g., data collection, mapping, searching). By increasing the number of robots, the efficiency in completing the task is also increased.

  • Patent number: 7198630
    Abstract: The present invention was developed by a neurosurgeon and seeks to mimic the results of primate neurological research which is indicative of a human's actual neurological control structures and logic. Specifically, the motor proprioceptive and tactile neurophysiology functioning of the surgeon's hands and internal hand control system from the muscular level through the intrafusal fiber system of the neural network is considered in creating the robot and method of operation of the present invention. Therefore, the surgery is not slowed down as in the art, because the surgeon is in conscious and subsconscious natural agreement and harmonization with the robotically actuated surgical instruments based on neurological mimicing of the surgeon's behavior with the functioning of the robot. Therefore, the robot can enhance the surgeon's humanly limited senses while not introducing disruptive variables to the surgeon's naturally occurring operation of his neurophysiology.

The instruments have end effectors that can be manipulated to hold and suture tissue. The robotic arms are coupled to a pair of master handles by a controller. The handles can be moved by the surgeon to produce a corresponding movement of the end effectors. The movement of the handles is scaled so that the end effectors have a corresponding movement that is different, typically smaller, than the movement performed by the hands of the surgeon. The scale factor is adjustable so that the surgeon can control the resolution of the end effector movement. The movement of the end effector can be controlled by an input button, so that the end effector only moves when the button is depressed by the surgeon.

  • Patent number: 6345213
    Abstract: A method provides an exact measurement of the tool center point (TCP) being carried out, preferably in the whole working area of the robot. In this measurement, the robot moves very slowly so that little heat is generated by the driving assemblies and the temperature gradients are as low as possible. The measurement can be made, for example, using a high-precision laser distance and angle measurement system. The measurement is carried out such that a measuring point is moved to working area points and then the deviations of the positions and/or orientations of the measuring point are determined using the laser distance and angle measurement system, i.e. a nominal/actual comparison is made. The TCP can preferably serve as the measuring point. The point must always be selected so that the positioning and orientation deviations of the kinematic chain with respect to the PCT can be determined with sufficient accuracy.

  • Publication number: 20020007690
    Abstract: A six-degrees-of-freedom parallel mechanism for micro-positioning work is disclosed. This mechanism freely performs a desired motion of translation and rotation of a moving platform using internal and external links actuated by linear actuators capable of precisely controlling the link positions, thus being effectively used as a 6d of parallel mechanism required to carry out a variety of micro-positioning works within a limited workspace. In the mechanism of this invention, a moving platform 10 is placed at an upper position, with a multiaxial spherical joint 40 mounted to the central portion of the moving platform 10. A base platform 20 is placed at a lower position of the mechanism. Three external links 30 couple the moving platform 10 to the base platform 20, while three internal links 50 couple the multiaxial spherical joint 40 to the base platform 20. In this mechanism, the internal links 50 are commonly coupled to the multiaxial spherical joint 40 so as to form a tetrahedral structure.

  • Publication number: 20010009233
    Abstract: A method and an apparatus for collating a plurality of groups of mail items, such as flats mail, each group being pre-sequenced according to prioritized delivery addresses, into a final sequenced set of the mail items from the groups, utilizing the prioritized delivery addresses. Each bundle of mail items is formed into a single input stream of the individual mail items. The mail items are transported along a conveyor system from the input stream to a staging station. The mail items are sorted at the staging station into a plurality of subsets of mail items re-sequenced as an intermediate step to achieving the final sequenced sets. The mail items are then collated and merged into a single output stream from the respective subsets of mail items in the final sequenced set. Portions of the output stream from the staging station are collected in batches having justified unbound edges which maintain the sequence consistent with the prioritized delivery order sequence of the mail for a given carrier route.

  • Patent number: 6244809
    Abstract: A system for performing minimally invasive cardiac procedures. The system includes a pair of surgical instruments that are coupled to a pair of robotic arms. The instruments have end effectors that can be manipulated to hold and suture tissue. The robotic arms are coupled to a pair of master handles by a controller. The handles can be moved by the surgeon to produce a corresponding movement of the end effectors. The movement of the handles is scaled so that the end effectors have a corresponding movement that is different, typically smaller, than the movement performed by the hands of the surgeon. The scale factor is adjustable so that the surgeon can control the resolution of the end effector movement. The movement of the end effector can be controlled by an input button, so that the end effector only moves when the button is depressed by the surgeon.
