Systems and methods related to intelligent grippers with individual cup control are disclosed. One aspect of the disclosure provides a method of determining grip quality between a robotic gripper and an object. The method comprises applying a vacuum to two or more cup assemblies of the robotic gripper in contact with the object, moving the object with the robotic gripper after applying the vacuum to the two or more cup assemblies, and determining, using at least one pressure sensor associated with each of the two or more cup assemblies, a grip quality between the robotic gripper and the object.

Examples relating to controlling extendable legs of a robotic device for use of a mechanical gripper are described herein. A robotic device may include one or more legs configured with a mechanical gripper coupled to the leg at a first position away from the distal end of the leg. The mechanical gripper may transition between the first position and a second position on the leg proximate to the distal end that enables the robotic device to use the mechanical gripper to perform grip operations. A control system of the robotic device may modify an orientation of the robotic device to at least position the robotic device on one or more legs other than the leg comprising the mechanical gripper, and transitions the mechanical gripper from the first position to the second position to perform the given grip operation of the input.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing planning for robotic placement tasks. One of the methods includes receiving a request for a robot to perform a placement task with an object, wherein the placement task has an associated insertion plane, wherein the request specifies a location on the insertion plane and an orientation angle for the object. A plan is generated for the robot including generating a rotational motion to transition the gripped object from an initial orientation to an orientation in which a principal vector is aligned with the insertion plane and the object is aligned with the orientation angle of the request.

A picking device includes: a workpiece holder in which a plurality of workpieces is stacked; a light receiver that receives reflected light from a workpiece stacked in the workpiece holder; a mover that relatively moves the light receiver with respect to the workpiece in such a manner that a distance between the light receiver and the workpiece is adjustable; an arm that picks the workpiece; a first hardware processor that calculates a distance between the light receiver and at least one workpiece among the plurality of workpieces; a second hardware processor that specifies a workpiece as a picking target among the plurality of workpieces or a region where the workpiece exists; and a third hardware processor that adjusts a distance between the light receiver and the workpiece calculated by the first hardware processor by controlling the mover in the region specified by the second hardware processor.

A robotic system includes one or more optical sensors configured to separately obtain two dimensional (2D) image data and three dimensional (3D) image data of a brake lever of a vehicle, a manipulator arm configured to grasp the brake lever of the vehicle, and a controller configured to compare the 2D image data with the 3D image data to identify one or more of a location or a pose of the brake lever of the vehicle. The controller is configured to control the manipulator arm to move toward, grasp, and actuate the brake lever of the vehicle based on the one or more of the location or the pose of the brake lever.

A manipulator including a shaft driven by a first motor, a rotatable unit, a linear slider, and a gripper is provided. The rotatable unit is coupled to the shaft, wherein the rotatable unit rotates with rotation of the shaft. The linear slider disposed on a first surface of the rotatable unit configured to slide from an initial position proximate to an outer edge of the rotatable unit to intermediate positions and to a final position proximate to a center of the rotatable unit. The gripper coupled to the linear slider to facilitate movement of the gripper along a first plane defined by the first surface of the rotatable unit.

The invention discloses an embedded system for dexterous hand, comprising: a central communication unit, several fingers, a palm; wherein the central communication unit communicates with the fingers, the palm and a host computer, and is configured to receive an operation instruction from the host computer, and convert the operation instruction into a control instruction and send it to the fingers and the palm; the fingers and the palm are designed to be compatible in hardware structure, and are connected by serial communication; the fingers and the palm move according to the control instructions. The fingers and palm are designed as embedded compatibility standards, which makes the dexterous hand more flexible and easy to maintain and use with lower cost. Thus, the dexterous hand has the advantages of high flexibility, high reliability, strong anti-interference, low cost, high transmission speed, convenient maintenance, and good user experience.

Disclosed herein are implementations that relate to determining tactile information using encoders coupled to one or more fingers of a robotic gripping device. The robotic gripping device may include a finger. The finger may include a deformable front face, a base link, a first encoder, and a second encoder. The first encoder may be coupled to the base link of the finger, and configured to detect a grip angle of the finger while the robotic gripping device is gripping an object. The second encoder may be coupled to the deformable front face of the given finger, proximate to the base link of the finger. Additionally, the second encoder may be configured to detect a bend angle of the deformable front face of the finger while the robotic gripping device is gripping the object.

A control apparatus of a robot that includes a flexible portion and a locking mechanism for fixing the flexible portion, the control apparatus including: a lock control unit configured to control locking and unlocking of the flexible portion; and an operation control unit configured to control operation of the robot using different types of control policies depending on whether the flexible portion is locked or unlocked. With this control apparatus, it is possible to effectively control a robot in which locking and unlocking of the flexible portion can be switched.

Provided is a robot system capable of appropriately removing an object that may deform depending on a placement state. A robot system according to the present disclosure is provided with: an imaging apparatus that captures an image of an object; a robot that picks up the object; an image processing apparatus that identifies the position of the object on the basis of the image captured by the imaging apparatus; and a robot controller that causes the robot to pick up the object, the position of which has been identified by the image processing apparatus. The image processing apparatus comprises: a teaching unit that sets a search range in which a feature amount for a pattern on the object in the image captured by the imaging apparatus may be obtained; a recognition unit that extracts the pattern having the feature amount within the search range in the image captured by the imaging apparatus; and a correction unit that corrects the search range on the basis of the feature amount of the pattern extracted by the recognition unit.
