A robotic end-effector to provide magnetic and mechanical finger grip. The end-effector has one or more magnets coupled to a palm, each of the one or more magnets having a magnet face to magnetically attach to a ferromagnetic object. The magnet face(s) define(s) a magnetic engagement surface with the magnet and the palm disposed on a proximal side of the magnetic engagement surface. A finger is pivotally coupled to the palm to grip the ferromagnetic object or another object. The finger has a deployed configuration wherein the finger is disposed distally with respect to the magnetic engagement surface and opposes the palm or the magnet face to grip the ferromagnetic object or other object. The finger has a retracted configuration wherein the finger is disposed proximally with respect to the magnetic engagement surface along with the magnet and the palm, and wherein the magnetic face forms an outermost contact surface.

Method of teaching robot and robot system

A robot system includes a robot, a vision sensor, and a controller. The vision sensor is configured to be detachably attached to the robot. The controller is configured to measure a reference object by using the vision sensor and calibrate a relative relationship between a sensor portion of the vision sensor and an engagement portion of the vision sensor, and teach the robot by referring to the relative relationship and by using the vision sensor, after the vision sensor is attached to the robot.

Gripper

A gripper may be provided that includes a motor, a jaw guide, a wedge head, a jaw, and a finger. The jaw guide is disposed on the motor and has a guide hole and a plurality of guide grooves. The wedge head is disposed in the guide hole and is able to perform up and down reciprocating movement by the motor. The jaw is disposed in the plurality of guide grooves respectively and is connected to the wedge head. When the wedge head moves in an up and down direction, the jaw is able to perform a reciprocating movement in a direction perpendicular to the up and down direction. The finger is disposed on the jaw. When the jaw moves in the direction perpendicular to the up and down direction, the finger moves together with the jaw, so that the movement of an object is limited.

A finger for a robotic gripper may include a flexible backbone, a plurality of jamming layers, and a membrane bag. The backbone may have a first side, a second side, a third side, and a fourth side. The backbone may include a flexible beam, and a plurality of branches attached to the flexible beam and spaced apart from one another. Each branch may include a first end surface extending along the first side, and a second end surface extending along the second side. The first end surfaces may collectively extend along a majority of the first side, and the second end surfaces may collectively extend along a majority of the second side. The jamming layers may be positioned along the third side or the fourth side. The membrane bag may be positioned over the jamming layers.

Haptic feedback system having two independent actuators

An electronic device comprises a haptic feedback system. The haptic feedback system includes a first haptic actuator coupled to a controller via a first set of two or more electrodes, and a second haptic actuator coupled to the first haptic actuator, and further coupled to the controller via a second set of two or more electrodes. The controller is configured to provide a first drive signal to the first haptic actuator via the first set of two or more electrodes, and to provide a second drive signal, different from the first drive signal, to the second haptic actuator via the second set of two or more electrodes. Combining two haptic actuators allows for a broader range of feedback and a heightened user experience.

Gripper for a bottle capping machine

A gripper for capping machines intended for screwing a cap onto a container adapted to being capped, in particular has a threaded neck for being capped. The gripper has a body capable of revolving on the axis of rotation, and at least two levers adapted to taking at least two different positions. The first position in which it is possible to insert a cap between the gripper levers and the second position in which the cap is locked between the gripper levers at least rotationally. At least one moving guiding shackle hinge-is mounted to the body and at least one lever which is slidingly mounted to the gripper body by means of a guide enabling movement of the lever in a horizontal direction, perpendicular to the axis of the gripper, and the end of the guiding shackle is slidingly and rotatably mounted to the at least one lever.
