A control device controls a robot including an arm, an end effector provided in the arm, and a force detector provided in the arm and configured to detect force. After bringing a first portion of the end effector close to a work surface and detecting contact of the first portion and the work surface on the basis of an output from the force detector, the control device brings a second portion of the end effector different from the first portion close to the work surface, detects contact of the second portion and the work surface on the basis of an output from the force detector, and teaches the robot a position of the end effector with respect to the work surface.

Control device, robot, and robot system

A control device includes a reception unit that receives first operation information and second operation information different from the first operation information; and a process unit that instructs a robot to execute operations based on the first operation information and the second operation information using a plurality of captured images of an imaged target object, the images being captured multiple times while the robot moves from a first posture to a second posture different from the first posture.

A new method for determining an attitude of a sensor with respect to a moving body is proposed. A movement vector is measured by a sensor mounted in the moving body. In addition, the attitude of the sensor with respect to the moving body is determined using the movement vector measured by the sensor when the moving body starts to move.

Attitude determination method, position calculation method, and attitude determination device

A method of determining the appropriateness of satellite orbit modeling is provided. The method includes calculating values of parameters, that the predetermined model has, on the basis of predicted position data including a first predicted position at a first point of time and a second predicted position at a second point of time of a positioning satellite in time series, calculating a first and a second calculated positions of the positioning satellite derived from the predetermined model by using the values of the parameters; and determining the appropriateness of the predetermined model using the values of the parameters, on the basis of first difference between the first predicted position and the first calculated position, and seconded difference between the second predicted position and the second calculated position. The predetermined model is used when approximating a satellite orbit of the poisoning satellite.

In a position calculating device, a first operational process of calculating at least a position of a moving object using the measurement result of an inertial positioning unit disposed in the moving object is performed by a first operation processing unit. A second operational process of calculating the position of the moving object using the result of the first operational process and the measurement result of a satellite positioning unit disposed in the moving object is performed by a second operation processing unit. An operational coefficient of the first operational process is adjusted using the result of the first operational process and the result of the second operational process by an operational coefficient adjusting unit.
