  • Patent number: 11961653
    Abstract: An electronic component includes an element body including two end surfaces opposite to each other and a bottom surface connected between the two end surfaces. A coil is provided in the element body and an external electrode is provided in the element body. In a first cross-section intersecting with the two end surfaces and the bottom surface of the element body, the external electrode has a first portion extending along a first surface that is one of the end surface and the bottom surface of the element body. The coil is disposed such that an outer circumferential edge of the coil faces the first surface of the element body. A shortest distance between the outer circumferential edge of the coil and the first surface of the element body is smaller than a minimum width of the first portion in a direction orthogonal to the first surface.

  • Patent number: 11707845
    Abstract: An assembly planning device: holds a partial-order graph showing assembly operations of parts and an order constraint based on a partial-order relationship of the assembly operations, an operation sequence template showing an operation sequence and a required time of the operation sequence, and part information showing parts that can be assembled by robots; refers to the part information to generate allocation plans in which the robot are allocated to the assembly operations shown by the partial-order graph; for each of the allocation plans, refers to the operation sequence template to allocate an operation sequence for each assembly operation shown by the allocation plan; calculates movement times of the robots in the allocated operation sequence; calculates an operation time in the allocation plan based on the movement times and the required time shown by the operation sequence template; and selects an allocation plan based on the operation times.

  • Patent number: 11518028
    Abstract: A trajectory generation device generates a trajectory of a robot for conveying an object. A path condition acquisition unit acquires path condition information including at least coordinates of a first via point which is a position of a reference point of a suction nozzle of the robot when the suction nozzle comes into contact with the object, and a velocity, an acceleration, and a jerk of the suction nozzle at the first via point. A pressurization distance and coordinate calculation unit calculates coordinates of a second via point which is a position of the reference point when the suction nozzle is pushed into the object, based on the path condition information; and a trajectory generation unit generates the trajectory of the suction nozzle which satisfies the path condition information and reaches an end point from a predetermined start point via the first via point and the second via point.

  • Publication number: 20220379473
    Abstract: A trajectory plan generation device executes a first search process for searching for a plurality of position candidates which are movement destinations of the tip portion within a predetermined distance from first trajectory information indicating positions and postures of the tip portion between the start point and the end point, a second search process for searching for a plurality of posture candidates of the tip portion that change within an allowable range by spherical interpolation based on postures of the tip portion at the start point and the end point, a determination process for determining second trajectory information indicating positions and postures of movement destinations of the tip portion from the first trajectory information based on the plurality of position candidates searched for by the first search process and the plurality of posture candidates searched for by the second search process, and an output process.

  • Publication number: 20200338730
    Abstract: A trajectory planning device calculating the trajectory of the robot arm reads robot arm configuration information including a configuration of the robot arm, and a position and a posture of an axis configuring a joint, start joint angle information, target posture information, and via-point posture information in which via points including positions and postures through which the hand of the robot arm passes are set, and generates a trajectory from a start point of the hand of the robot arm to an end point by an interpolation between via points, calculates a joint angle of each axis from a posture and a position of the hand of the robot arm based on the robot arm configuration information, converts the trajectory generated in a physical space into a joint angle space by an inverse kinematics unit, and then smooths the trajectory.
