A control apparatus makes a robot hand grip a work for measurement. The control apparatus controls the operation of a robot arm so that the robot arm keeps a force of striking the work for measurement against a reference constant, while making the end portion of the robot arm rotate around the end axis, in a state of making the outer periphery F3 of the work for measurement, which is gripped by the robot hand, strike against the reference jig. The control apparatus acquires a detection result detected by an encoder of each of the joints when the end portion of the robot arm has been rotated. The control apparatus calculates a correction amount of trajectory data based on eccentricity of a central axis with respect to an end axis, by using the detection result of the encoder, and corrects the trajectory data, based on the correction amount.

Robot system equipped with camera for capturing image of target mark

A robot system which is inexpensive and can easily measure a position of a target point. The system stores feature quantities of an image of a target mark included in an image acquired as reference data when the target mark is placed at a known first target mark position at the robot coordinate system and stores the first target mark position with respect to an arm tip as the position of the tool center point. The system compares the feature quantities obtained from the image acquired when the target mark is arranged at a second target mark position and the feature quantities of the reference data to make the arm tip move and calculates the second target mark position at the robot coordinate system based on a second robot position corresponding to the position of the arm tip after movement and the position of the tool center point.

Mobile construction robot

A smart drilling system that includes a controller, a drilling machine with an optical marker, and a tracker station at a fixed spot of a construction site. The drilling machine includes an optical marker. The tracker station acquires the location of the drilling machine and its drill through tracking the optical marker. The drilling machine is moved into positions of multiple different work regions. The tracker station sequentially acquires the location of the multiple different work regions and transmits the acquired location information to the controller, such that, by using the transmitted locations, the controller converts drilling machine coordinates into desired perforation coordinates and recognizes an orientation of the drilling machine. The controller also recognizes a perforable point at a current position of the drilling machine through the location information of the drilling machine.
