Abstract: Banknotes directed along the formation channels of a machine for making up bundles are caused to accumulate into an ordered stack at the outlet of each channel. The machine utilizes a bundling unit equipped with a sliding carriage and a first gripper, of which the operation is piloted by sensors associated with each outlet and governed by a monitoring and control unit in such a way that the gripper will address the single outlet each time a stack is formed, then pick up the stack and pass it to a second gripper forming part of a translate and tilt unit; this same unit proceeds first to offer the stack of banknotes to a binder, by which two wrapping bands are applied to the two ends to complete the bundle, and thereafter to tilt the bundle into the path of a push rod which directs it toward a packaging and/or storage station.

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 tissues. 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.

Abstract: An improvement is set forth in a robotic arm structure which includes at least two links. .theta. motion is provided about a primary axis at the proximal end portion of the proximalmost of the links. R motion proceeds radially from the primary axis whereby the distal end portion of the distalmost of the links can be moved in a radially extending straight line. An end effector is pivotally mounted for rotation relative to the distal end portion of the distalmost link about an end effector axis which is parallel to the primary axis. The structure is improved by adding one or more a yaw motor, a roll motor and a pitch motor for rotating the wrist of the arm about the respective axes. A sensor array senses the R, .theta., Z and yaw, roll and/or pitch motions and creates and transmits electronic signals representative thereof to a computer controller which monitors and controls the R, .theta., Z and yaw, roll and/or pitch motions.

Abstract: A new generation of hybrid form multi-axis machine tools is described. The hybrid machine tools comprise a position mechanism and an orientation mechanism. Both mechanisms are three-DOF parallel mechanisms that can be connected either in series to form a hybrid parallel-serial manipulator, or in parallel to form a cooperating machine. The position mechanism is used for manipulating the position and the orientation mechanism is used for manipulating the orientation of an object. Six-axes machining of a workpiece is achieved by coordinating the motions of the position and orientation mechanisms. This approach has several important advantages. First of all, a high stiffness, low inertia, and high speed machine tool is realized by using the parallel construction. Secondly, its direct and inverse kinematic solutions could be solved in closed forms which would greatly simplify the control and path planning problems. Thirdly, it has a relatively large workspace in comparison to fully parallel platform manipulators.

Abstract: Both a pneumatic, linear actuator operating as a slave actuator and a master linear actuator formed by an electric motor driven screw mechanism are linked to drive a load. The high accuracy master linear actuator has a conventional control system which dominates the control of load position or other control variable. A force sensor detects the force applied to the load by the master actuator or the force is calculated by a computer and the sensed force signal is applied to a slave actuator control to cause the slave to apply a supplemental force, typically considerably greater than the master actuator force, to the load as a function of the master actuator force. This obtains the high accuracy characteristic of the master actuator system simultaneously with the high force characteristic of the slave actuator.

Abstract: In order to synchronize the operations of at least two industrial robots which can operate independently of each other in accordance with their respective operation programs, the time is obtained which is required for one of the robots serving as the master to move from one working position to the next position at which it operates jointly with the remaining robot. The remaining robot serving as the slave is moved from the position where it exists at present to another position corresponding to said next position, thereby synchronizing the operations of all the robots. An apparatus for such synchronous control comprises a program used to compute with a specified moving speed the interpolation movement due to which each robot is moved between the adjacent working positions and a program used to compute the interpolation movement with a specified moving time. In case of the asynchronous control, the robots move independently in accordance with their respective operation programs.

Abstract: This invention relates to the field of computer controlled robotics. More specifically, it relates to a novel method and algorithm to symbolically decompose the robot jacobian matrix, in such a way that the robot jacobian Moore-Penrose pseudo-inverse is obtained symbolically even when the robot jacobian is ill conditioned or rank deficient, and to a general purpose computer and method to perform the symbolic steps. The resulting symbolic pseudo-inverse, after symbolic reduction techniques, is not only efficient from the point of view of number of floating point operations, but is also accurate (exact) and stable. It removes the restrictions imposed by the computational complexity of the jacobian pseudo-inverse, especially when the robot jacobian is ill conditioned (robot near/at singularities). This method is sufficiently fast to allow real time control of the robot and is sufficiently stable to allow good robot performance near singularities.
