A pattern matching unit carries out a pattern matching between a photographed image obtained by photographing a workpiece with a monocular camera and a first plurality of models having a plurality of sizes and a plurality of angles, and selects a model having a size and an angle with the highest degree of matching. A primary detection unit detects a position and an angle of an uppermost workpiece based on the selected model. An actual load height calculation unit calculates an actual load height of the uppermost workpiece based on a hand height. A secondary detection unit re-detects the position and the angle of the uppermost workpiece based on a model having a size and an angle with the highest degree of matching selected by carrying out a pattern matching between the photographed image and a second plurality of models selected or newly created based on the actual load height.

A robotic system for inspecting a part comprises a robot comprising an articulating arm and an end effector, coupled to the articulating arm. The robotic system further includes three or more proximity sensors on the end effector and spaced apart from each other. Each of the proximity sensors is configured to detect a measured distance from the proximity sensor to a surface, such that the end effector is displaced from the surface. The robotic system includes a controller configured to receive measured distances from the proximity sensors. The controller is also configured to orient the end effector to a predetermined orientation based on the measured distances. The controller is further configured to calculate an average of the measured distances. Additionally, the controller is configured to move the end effector to a predetermined operating distance from the surface based on the average of the measured distance.

A method of estimating an attitude of a control device for controlling operating machines, where the control device has a plurality of pushbuttons for controlling the movement of an operating machine along respective directions, the method having the following steps: —preliminary estimating the attitude of the control device using data from an accelerometer and a magnetometer onboard of the control device; —updating of the preliminary estimate of the attitude of the control device using data from a gyroscope onboard of the control device.

A calibration method for numerical controlled machine tools (1), which uses a kinematic model to generate a compensation model for the positioning error occurring with the movement of the linear (X, Y, Z) and rotation axes (B, C, A) of a machine tool (1). The calibration method measures the positions of a calibration ball (6) with a measurement sequence which includes the combined movement of the calibration ball (6) around two rotation axes (C, B or C, A), wherein the measurements around a first rotation axis (C) include at least two rotational position movements around a second axis (B or A).

A robot system (100) of the present disclosure includes a robot (101) installed in a workarea (201), an interface (102), a display (105), and a control device (111). When operating the robot (101) to perform a kind of work defined beforehand to a workpiece (300) based on manipulational command information on the robot (101) inputted from the interface (102), the control device (111) displays on the display (105) a spatial relationship between the workpiece (300) and the robot (101) in a state where the workpiece and the robot are seen from a direction different from a direction in which an operator looks at the robot (101) from a manipulation area (202) that is a space different from the workarea (201), based on three-dimensional model information on the workpiece (300), three-dimensional model information on the robot (101), and the manipulational command information.
