Abstract:
A control system and method generate joint variables for motion or posing of a target system in response to observations of a source system. Constraints and balance control may be provided for more accurate representation of the motion or posing as replicated by the target system.
Abstract:
An apparatus and method for enabling an uncalibrated, model independent controller for a mechanical system using a dynamic quasi-Newton algorithm which incorporates velocity components of any moving system parameter(s) is provided. In the preferred embodiment, tracking of a moving target (40) by a robot (10) having multiple degrees of freedom is achieved using an uncalibrated model independent visual servo control. Model independent visual servo control is defined as using visual feedback to control a robot's servomotors without precisely calibrated kinematic robot (10) model or camera (36) model. A processor (17) updates a Jacobian and a controller (14) provides control signals such that the robot's end effector (34) is directed to a desired location relative to a target (40) on a workpiece (38).
Abstract:
Establishing alignment or a desired orientational relationship between a master (700) and a slave (10) of a telerobotic system (200). The invention can advantageously be used in a surgical apparatus. A method of establishing a desired orientational relationship between a hand-held part (699) of a master control (700) and an end effector (58) of an associated slave (10) as viewed in an image displayed on a viewer (202) is provided. The method includes causing the end effector (58) to remain stationary, determining a current orientation of the end effector (58) relative to a viewing end of an image capturing device (304) operatively associated with the viewer (202) and determining a desired corresponding orientation of the hand-held part (699) of the master control (700) relative to the viewer (202), at which orientation the desired orientational relationship between the hand-held part (699) of the master control (700) and the end effector (58) would be established. The invention extends to a control system arranged to cause the desired orientational relationship between the hand-held part (699).

Abstract:
A coordinated joint control system for controlling a coordinated joint motion system, e.g. an articulated arm of a hydraulic excavator blends automation of routine tasks with real-time human supervisory trajectory correction and selection. One embodiment employs a differential control architecture utilizing an inverse Jacobian. Modelling of the desired trajectory of the end effector in system space can be avoided. The invention includes image generation and matching systems.
