A route is generated for a robot with multiple parts connected rotatably. Multiple waypoints indicating a posture of the robot are registered. It is determined whether a registration waypoint is allowable as the posture of the robot. The route is generated to connect an added waypoint and an existing waypoint. It is determined whether the route satisfies the condition that the robot is operable. The adding of the waypoint and the generating of the route are repeated until the route reaches the end point. Determination results of the registration waypoint and the generated route and the condition determined not to be satisfied are displayed.

A layout generation device includes: a waypoint registration unit, an arrangement generation unit, an arrangement evaluation unit, an arrangement extraction unit, a path determination unit, a path generation unit, an arrangement exclusion unit, and an arrangement evaluation update unit. The arrangement evaluation unit evaluates, as an evaluation value, an operation time of a robot without considering an obstacle for each of arrangements. The arrangement extraction unit extracts an arrangement having a best evaluation value from among the evaluated arrangements by the arrangement evaluation unit. The path determination unit determines whether or not an extracted arrangement extracted by the arrangement extraction unit needs to avoid an obstacle in terms of an operation of the robot via a waypoint.

Layout generation device, layout generation method, and layout generation program

A motor includes a motor body, a speed reduction unit, a brush holder, and a circuit board. The motor body rotationally drives a rotation shaft. The speed reduction unit reduces speed of rotation of the rotation shaft. The brush holder is held by a motor case of the motor body and a gear housing of the speed reduction unit. The circuit board is arranged in a board receptacle that is open in a direction orthogonal to a motor flattened surface. The brush holder includes a terminal that is directly and electrically connected to the circuit board.

Motor

This clutch includes an annular clutch housing, a rotationally driven drive-side rotating body, a driven-side rotating body, a rolling body, and a support member. The clutch is configured such that, when the drive-side rotating body starts to rotate when driven, the drive-side rotating body comes into contact with the support member in a rotational direction and presses the rolling body in the rotational direction through the support member, thereby releasing the rolling body from gripping effected by the clutch housing and the driven-side rotating body. The support member includes a load generation section for generating a load which makes it difficult for the support member to rotate about the rotation axis of the drive-side rotating body when at least the drive-side rotating body starts to rotate when driven.

Clutch and motor

A clutch includes a roller arranged between a clutch housing and a driven side rotating body. The roller is rotated about a rotation axis of a drive side rotating body together with the drive side rotating body when the drive side rotating body is rotationally driven. The roller hinders rotation of the driven side rotating body by being sandwiched between the clutch housing and the driven side rotating body when the drive side rotating body is not rotationally driven. The support member sandwiches the roller between the clutch housing and the driven side rotating body. The support member rotates about the rotation axis of the drive side rotating body together with the drive side rotating body. The grease is arranged between the clutch housing and the roller. The support member restricts rotation of the roller about a central axis of the roller.

The axial direction of a worm wheel is defined as a motor short-transverse direction, and a plane orthogonal to the motor short-transverse direction is defined as a motor flat plane. An imaginary plane contacting a first end of a sensor magnet in a motor short-transverse direction and parallel with the flat plane is defined as a first imaginary plane. An imaginary plane contacting a second end of the sensor magnet in the motor short-transverse direction and parallel with the flat plane is defined as a second imaginary plane. A control circuit board is provided with a rotation detecting element that detects rotation of the rotary shaft of the motor. The control circuit board is arranged to be parallel with or inclined relative to the flat plane, and is provided between the first and second imaginary planes.

A joint structure includes a drive side insertion portion of a drive shaft, a driven side insertion portion of a driven shaft, and a coupling. The coupling includes a drive shaft insertion bore, which receives the drive side insertion portion, and a driven shaft insertion bore, which receives the driven side insertion portion. The drive shaft insertion bore includes a wall surface that engages the drive side insertion portion. The driven shaft insertion bore includes a wall surface that engages the driven side insertion portion. A drive side clearance in the drive shaft insertion bore allows the drive side insertion portion to move in the radial direction. A driven side clearance in the driven shaft insertion bore allows the driven side insertion portion to move in the radial direction.

Joint structure, clutch, and motor

An arithmetic processing apparatus performs arithmetic by a neural network in which multiple processing layers are hierarchically connected. The arithmetic processing apparatus corresponding to one of the multiple processing layers includes a convolution arithmetic portion and a pooling processing portion. The convolution arithmetic portion receives an input data from another of the plurality of processing layers, performs convolution arithmetic to the input data, and in each arithmetic cycle, outputs a part of all convolution arithmetic result data required for single pooling processing. The pooling processing portion performs the single pooling processing to the all convolution arithmetic result data before executing activation processing.

Arithmetic processing apparatus

A motor includes a motor unit, a gear housing coupled to the motor unit, and a connector module including a connector housing coupled to the gear housing. The motor unit includes a rotation shaft and a power terminal. The gear housing accommodates a deceleration mechanism that outputs decelerated rotation of the rotation shaft. The connector terminal and the circuit substrate are fixed to the connector housing. The power terminal is connected to a socket of the connector terminal when coupling the connector housing to the gear housing. The connector terminal includes a fixed portion fixed to the connector housing, a substrate connecting portion connected to the circuit substrate, and a supported portion located closer to the socket than the substrate connecting portion. The connector housing includes a terminal supporting portion that supports the supported portion from the rear in the coupling direction.

Motor connection module for suppressing connecting defects

A clutch includes a driving-side rotating body, a driven-side rotating body, a holding case, and a power transmitting member held by one of the driving-side rotating body and the holding case. The power transmitting member is moved between a non-engaging position and an engaging position where the driving-side rotating body engages with the driven-side rotating body. The clutch further includes a guiding member held by the other of the driving-side rotating body and the holding case. The guiding member has a cam portion engaged with the power transmitting member and guides movement of the power transmitting member between the engaging position and the non-engaging position. Relative rotation between the driving-side rotating body and the holding case occurs, resulting in that the power transmitting member is guided by the cam portion to move from the non-engaging position to the engaging position.

Clutch, motor and vehicle door opening/closing device

When a drive shaft is in a non-drive state, a second drive rotor is in a non-engaged state with a driven rotor with respect to its own rotating direction. When the drive shaft is in a drive state, a rotating force of a first drive rotor is transmitted to the second drive rotor through an urging member. As a result, a power transmitting member revolves, and a centrifugal force arranges the power transmitting member at a second clamping position. The second drive rotor receives a reaction force from a driven rotor via the power transmitting member. As a result, the second drive rotor is relatively rotated in an opposite direction to a rotating direction of the first drive rotor with respect to the first drive rotor, against an urging force of the urging member. As a result, the first drive rotor is engaged with the driven rotor with respect to its own rotating direction. Accordingly, the clutch is stably operated.
