  • Patent number: 11738469
    Abstract: A control apparatus includes a memory and a processor. The processor is configured to control a distal end portion of a robot to rotate around first and second distal end axes, perform a first control mode in which the distal end portion rotates around the first and second distal end axes, perform a second control mode in which the distal end portion rotates around the first distal end axis and does not rotate around the second distal end axis, switch the first control mode to the second control mode when the first distal end axis is perpendicular to a working surface, and control the distal end portion to work while performing the second control mode and maintaining a state in which the first distal end axis is perpendicular to the working surface after the first control mode is switched to the second control mode.

  • Patent number: 11420330
    Abstract: A robot control device according to an aspect of the invention is a robot control device that controls a robot on the basis of a simulation result of a simulation device that performs a simulation of operation of a virtual robot on a virtual space. In the simulation, a first region and a second region located on an inside of the first region can be set on the virtual space. In the case where the virtual robot operates, when a specific portion of the virtual robot intrudes into the first region, operating speed of the virtual robot is limited. When the specific portion of the virtual robot intrudes into the second region, the operation of the virtual robot stops or the virtual robot retracts from the second region.

  • Publication number: 20200130198
    Abstract: A control apparatus includes a robot control unit that controls a robot having a robot distal end portion pivoting about respective axes of a distal end first axis and a distal end second axis, and a display control unit that displays a window containing a first operation part for pivoting the robot distal end portion about the distal end first axis using the robot control unit and a second operation part for pivoting the robot distal end portion about the distal end second axis using the robot control unit. In the window, a control mode can be switched between a first control mode of enabling operations by the first operation part and the second operation part and a second control mode of enabling the operation by the first operation part and disabling the operation by the second operation part.

  • Patent number: 6909093
    Abstract: To provide a thermopile infrared detecting element capable of accurate temperature measurement at low cost. An infrared detecting element 1 using a silicon nitride film as a first structure layer 22 constituting a structure of a membrane portion 4 is provided. Unlike silicon oxide, the first structure layer 22 has internal stress in the tensile direction, and can thus prevent the occurrence of bending. Also, diodes D1 and D2 can be formed in a silicon substrate 2 by using the first structure layer 22 as an element isolation region, and thus deformation of a thermopile 12 due to a change in the environment can be prevented to suppress measurement error of the thermopile 12. Furthermore, a high accuracy infrared detecting element capable of accurately detecting the temperature of cold junctions using the diodes D1 and D2 can be provided.
