Patent number: 8534729Abstract: A robotic gripper (10) has fingers (12) that are configured to grasp an object, and an actuator (20) for driving the fingers. The actuator has a drive train (30) connected to the fingers for driving the fingers, an impact mechanism (40) mechanically connected to the drive train for driving the drive train, and a motor (50) connected to the impact mechanism for driving the impact mechanism. The impact mechanism generates a series of impacts that are delivered to the drive train when the impact mechanism is loaded beyond a threshold torque. The drive train is a back-drive inhibited drive train provided by a worm drive (32, 34) that is mechanically coupled to the impact mechanism.Type: GrantFiled: August 4, 2011Date of Patent: September 17, 2013Assignee: Harris CorporationInventors: Loran J.

Patent number: 8534728Abstract: A method for grasping an object includes moving a first and second gripping pad (116) respectively to first and second locations in which a first face (117) of the first gripping pad is opposed from a second face (117) of the second gripping pad and spaced apart a distance. Two or more of pins (118) included in each gripping pad are extended from at least the first face in a direction toward the second face. Thereafter, an extension distance for each of the pins is independently determined responsive to a resistance encountered by each of the pins as a result of the extending. As a result of the independently determining step, an object-defined gripping contour is provided as formed by distal ends of the pins.Type: GrantFiled: November 19, 2012Date of Patent: September 17, 2013Assignee: Harris CorporationInventors: Paul M.

Publication number: 20120185099Abstract: Method and system for telematic control of a slave device. A stiffness of a material physically contacted by a slave device (202) is estimated based on information obtained from one or more slave device sensors (216, 217). Based on this stiffness estimation, a motion control command directed to the slave device is dynamically scaled. A data processing system (204) is in communication with a control interface (203) and the slave device. The data processing system (204) is configured to generate the motion control commands in response to sensor data obtained from the control interface. The system (200) also includes a stiffness estimator (602) configured for automatically estimating a stiffness of a material physically contacted by the slave device based on information obtained from the slave device sensors. A scaling unit (607) is responsive to the stiffness estimator and is configured for dynamically scaling the motion control command.Type: ApplicationFiled: January 19, 2011Publication date: July 19, 2012Applicant: HARRIS CORPORATIONInventors: Paul M.

Publication number: 20120185098Abstract: Method and system for telematic control of a slave device. Displacement of a user interface control is sensed with respect to a control direction. A first directional translation is performed to convert data specifying the control direction to data specifying a slave direction. The slave direction will generally be different from the control direction and defines a direction that the slave device should move in response to the physical displacement of the user interface. A second directional translation is performed to convert data specifying haptic sensor data to a haptic feedback direction. The haptic feedback direction will generally be different from the sensed direction and can define a direction of force to be generated by at least one component of the user interface. The first and second directional translation are determined based on a point-of-view of an imaging sensor.Type: ApplicationFiled: January 19, 2011Publication date: July 19, 2012Applicant: HARRIS CORPORATIONInventors: Paul M.
