SYSTEMS AND METHOD FOR ROBOTICS CONTROL UNDER CONTACT
A system comprises a database; at least one hardware processor coupled with the database; and one or more software modules that, when executed by the at least one hardware processor, receive at least one of sensory data from a robot and images from a camera, identify and build models of objects in an environment, wherein the model encompasses immutable properties of identified objects including mass and geometry, and wherein the geometry is assumed not to change, estimate the state including position, orientation, and velocity, of the identified objects, determine based on the state and model, potential configurations, or pre-grasp poses, for grasping the identified objects and return multiple grasping configurations per identified object, determine an object to be picked based on a quality metric, translate the pre-grasp poses into behaviors that define motor forces and torques, communicate the motor forces and torques to the robot in order to allow the robot to perform a complex behavior generated from the behaviors.
Hand intended to equip a humanoid robot
A hand intended to equip a humanoid robot, the hand includes a palm and at least one finger extending along a first axis, the hand being capable of picking up an object, the finger comprising a first phalanx linked to the palm by a first motorized pivot link and a second phalanx consecutive to the first phalanx linked to the first phalanx by a second pivot link. The finger comprises a first mechanism linking the palm to the second phalanx configured such that the rotation of the first phalanx about the second axis causes the second phalanx to rotate about the third axis, and a second mechanism linking the palm to each of the phalanges configured to actuate the finger in such a way that the finger wraps around the object to be picked up, and the second mechanism is configured to deform the first mechanism.
AUTONOMOUSLY ENCAPSULATING GRIPPER TOOLING
A gripper tooling includes: a gripper having a gripper body and an angular jaw; a rotor fixedly connected to the angular jaw; and a tooling member for gripping a workpiece, the tooling member including: a base pivotally connected to the rotor; a middle segment pivotally connected to the base; a distal segment pivotally connected to the middle segment; an adducting tendon having a proximal end attached to the rotor and a distal end attached to the distal segment, the rotor for rotating relative to the base and thereby for tensioning the adducting tendon; and an abducting tendon having a proximal end attached to the base and a distal end attached to the distal segment such that the tooling member can autonomously grip the workpiece as the angular jaw rotates toward the workpiece and the tooling member autonomously returns to an ungripped position as the angular jaw rotates away from workpiece.
Actuator
An actuator (1) is described having a first part (4), a second part (2), and a body portion (3) between the first and second parts, wherein the body portion includes at least one chamber (14) configured to be pressurised and the body portion has a longitudinal axis; and a plurality of cables (6,7,8,9), wherein each of the plurality of cables is arranged in a respective at least partial spiral with respect to the longitudinal axis of the body portion (3); and wherein the plurality of cables are arranged such that the application of a selected force to at least one of the cables causes a desired movement of the first part relative to the second part.
SLIDER AND SURGICAL INSTRUMENT
A slider is provided. A slider of the present disclosure includes a slider body disposed to be movable in a linear direction relative to a surgical instrument, and two holders disposed on the slider body for holding ends of a wire between the two holders to retain the wire in an annular shape. At least a first holder of the two holders is provided with an insertion hole for inserting and passing the ends of the wire toward an outside from between the two holders.
ROBOTIC MANIPULATORS
A robot comprising: a chopstick, configured for at least four degrees of freedom of movement, a stiff body of shape and proportions approximate to a pool cue; an electromagnetic actuator, comprising a motor, for each degree of freedom of movement coupled with the stiff body, wherein the functional mapping from each actuator's motor current to torque output along an axis of motion is stored, and used in concert with a calibrated model of the robot for effective impedance control; and a 6-axis force/torque sensor mounted inline between the actuators and each chopstick.
WEARABLE ROBOT HAND DEVICE REMOVABLE FROM HAND STRUCTURE
Embodiments relate to a wearable robot hand device removable from a hand structure, including: at least one of first and second exglove modules as one or more exglove modules attached to the hand structure, the first exglove module being attached to a surface of the hand structure and the second exglove module being attached onto a exglove of the first exglove module.
Device for enhancing a subject's grasping capability
A device for enhancing a user's grasping capability comprises a belt-like support configured to be tightly fitted about a user's part of the body; an articulated gripping element having a plurality of phalanxes: proximal, fixed to the support, intermediate and distal, which are articulated to each other by articular joints; a motor unit fixed to the support; a winding drum; a tendon partially wound on the drum and extending along the phalanxes and the joints, arranged so that, by pulling it from the drum, the phalanxes rotate about respective articular joints and move the articulated gripping element from an extended position to a gripping bow-shaped position, causing a flexion/extension movement of the articulated gripping element, the joints configured so that by releasing the tendon from the drum, the phalanxes rotate about the respective joints and move the articulated gripping element between gripping bow-shaped position and extended position.
Gripping mechanism and gripping tool
A gripping mechanism includes: two gripping pieces pivoted relative to each other about a pivot axis; a base supporting the gripping pieces in a pivotable manner; a pulling pulley rotatably supported about a rotation axis parallel to the pivot axis; and a wire wound around the pulley, and causing, with a pulling force, the pulley to move the rotation axis. The pulley is disposed so that a resultant force of tensile forces of the wire becomes greater than the pulling force and generates a moment causing the gripping pieces to be pivoted relative to each other in closing direction. The base includes a first hole. At least one of the gripping pieces includes a second hole inclined in one direction with respect to the longitudinal axis of the first hole. The rotation axis is provided so as to be movable along the longitudinal axes of the individual holes.
