End effector assemblies for drilling a plurality of spaced-apart holes in a part, robots including the end effector assemblies, and associated methods are disclosed herein. The end effector assemblies include a first force application structure, an end effector, and a second force application structure. The first force application structure is configured to apply a first force to a surface of the part. The end effector is configured to selectively transition the first force application structure between a retracted state and an extended state and to selectively extend a drill bit into the part and subsequently retract the drill bit from the part. The second force application structure is configured to continuously apply a second force to the surface of the part while the first force application structure is in the retracted state and as the end effector assembly transitions from a first predetermined location to a second predetermined location.

A linear-object management structure for a robot, where a post-attached linear object is guided via the same path as a basic cable from inside a base and fixed at the position of a first fixing member, is subsequently extended forward beyond the basic cable, through a path closer to a first axis than the basic cable is, is curved in a direction along a first arm, is fixed to a side surface of the first arm, at the position of a second fixing member, such that a certain length margin required for the operation of the first arm is provided between the position of the first fixing member and the position of the second fixing member, and is guided to an upper-side movable portion along the first arm.

In a motor including an armature, and a field system having a main pole magnetized in first directions in which a distance from the armature is defined and a sub-pole adjacent to the main pole in second directions orthogonal to the first directions and magnetized in the second directions and forming a Halbach array, a first dimension of the main pole in the second directions, a second dimension of the main pole and the sub-pole in the first directions, and a third dimension as a sum of the dimensions of the main pole and the sub-pole in the second directions are determined according to a flux content generated in a surface of the field system at the armature side.

The invention relates to a delta robot (1) with at least two robot arms (2a, 2b, 2c), preferably three robot arms (2a, 2b, 2c), which can be moved relative to a robot base (3) via a respective motor (5a, 5b, 5c) arranged on the robot base (3) and associated with the respective robot arm (2a, 2b, 2c), wherein the motors (5a, 5b, 5c) each comprise part of a motor-controller-encoder unit (4a, 4b, 4c) with integrated servo-controller (6a, 6b, 6c) and encoder in order to increase the mechanical accuracy and efficiency of the delta robot (1).

An integrated circuit includes a nexus and a first, a second, a third, and a fourth circuit board. Each of the first and second circuit boards is coupled to opposing sides of the nexus, and each of the third and fourth circuit boards is coupled to opposing sides of the second circuit board. The integrated circuit is transitionable between a first, open configuration, in which the first, second, third and fourth circuit boards and the nexus are substantially coplanar, and a second configuration, in which the first, second, third and fourth circuit boards and the nexus are coupled to one another to define a cavity therein.

Provided is a robot gripper. The robot gripper comprises: at least two finger units which symmetrically face each other; finger tips which are provided at the terminal ends of the finger units and linked with the operation of the finger units; and a driving unit connected to the finger units so as to operate the finger units. When the finger units are operated, the finger tips pinch-grip an object by moving toward an inner area, which at least two of the finger units form by facing each other, while adapting to conflicts with constraints of the external environment. A force applied to the finger tips in order to enable the pinch grip can act in a direction that raises the object while being applied toward the inner area, or act in a direction lowering the object while being applied toward the inner area.
