Control method via which an operator can control a robot, using control means that can be positioned as desired at various points on an item that is to be handled, the method comprising at least one step (303) of determining the position and attitude of the control means by measuring forces applied to the control means to define a first load pattern, and corresponding forces for example at the robot gripper member, a step (305) of determining setpoints for controlling the robot (1) in terms of force or in terms of force/position on the basis at least of the measurements of forces on the control means which are applied for moving the item (15) and on the basis of the position and attitude determined during the determining step (303), and a control step (307) during which the determined setpoints are transmitted to the robot (1). Another subject of the invention is a control system employing such a method.

A remote pendant (20) for a metrology machine. The pendant comprises a non- configurable user interface which is an extension of the main computer monitor wherein the screens shown on a monitor of the pendant are created by application and/or control software running on the computer control of the machine. The remote pendant further comprises camera and/or webcam (30) features as well as voice recording capabilities. With the remote pendant, the machine operator can view messages appearing on the main computer screen and respond to any prompts via a touch screen (28) on the pendant thereby eliminating the need to return to the machine operator station.

A control method for a power assist device (50) provided with an operation handle (6), a force sensor (7) that detects an operation force applied to the operation handle (6) and an orientation (θh) of the operation force, a robot arm (3), and an actuator (11). When the orientation (θh) of the operation force is detected to be within a predetermined angle range with respect to a preset advancing direction of the operation handle, the actuator (11) is controlled so as to move the operation handle (6) along the advancing direction (A) by employing only a component of the operation force along the advancing direction; and when the orientation (θh) of the operation force is detected to be outside the predetermined angle range, the actuator is controlled to move the operation handle (6) by the operation force applied to the operation handle (6) and the orientation of the operation force.

This invention relates to establishing alignment or a desired orientational relationship between a master and a slave of a telerobotic system. The invention can advantageously be used in a surgical apparatus. A method of establishing a desired orientational relationship between a hand-held part of a master control and an end effector of an associated slave as viewed in an image displayed on a viewer is provided. The method includes causing the end effector to remain stationary, determining a current orientation of the end effector relative to a viewing end of an image capturing device operatively associated with the viewer and determining a desired corresponding orientation of the hand-held part of the master control relative to the viewer, at which orientation the desired orientational relationship between the hand-held part of the master control and the end effector would be established. The method further includes causing the hand-held part of the master control to be moved into the desired corresponding orientation. The invention extends to a control system arranged to cause the desired orientational relationship between the hand-held part of the master control and the end effector of the associated slave., as viewed in the displayed imaged on the viewer, to be established when operative control between the master control and the slave has been interrupted.

The proposed robot arm allows an improved ergonomic operation during a learning programming process of a robot comprising such a robot arm.
摘要:
A method, a non-transitory computer readable medium, and an apparatus for operating the robotic control system comprising a master apparatus (64) in communication with an input device (58, 60) having a handle (102) and a slave system (54, 74) having a tool (66, 67) having an end effector (73) whose position and orientation is determined in response to a current position and current orientation of the handle. The method involves producing a desired end effector position and orientation in response to a current position and orientation of the handle. The method involves causing the input device to provide haptic feedback that impedes translational movement of the handle, while permitting rotational movement of the handle and preventing movement of the end effector, when a rotational alignment difference between the handle and the end effector meets a disablement criterion. The method further involves re-enabling translational movement of the handle when the rotational alignment difference meets an enablement criterion.
