In a robot control apparatus mounted on a mobile robot, movement of a human existing in front of the robot is detected, and the robot is moved in association with the movement of the human to thereby obtain path teaching data. When the robot moves autonomously according to the path teaching data, a robot movable area with respect to the path teaching data is calculated from positions of the ceiling and walls of the robot moving space or positions of obstacles detected by a surrounding object detection unit, whereby a moving path for autonomous movement is generated. The robot is controlled to move autonomously by a drive of a drive unit according to the moving path for autonomous movement.

Disclosed is a method of controlling an applicator coupling skin heating energy to the skin. The skin heating energy is applied to the skin as a function of electrode-to-skin coupling quality. In cases where only partial electrode-to-skin contact is detected the skin heating energy is adjusted accordingly. Disclosed is also an apparatus for implementing this method.

Methods and systems for navigating medical devices are provided. A patient is imaged while a medical device is moved within the patient. A position (e.g., a location and / or orientation) of the moving medical device is detected within a coordinate system (e.g., a three-dimensional coordinate system), a position of the imaging field of view relative to the patient is adjusted based on the detected medical device position, such that the relevant tissue region of the patient is within the field of view. For example, the field of view can be centered over the medical device or centered just distal to the medical device portion. The direction of view may be oriented at an angle perpendicular to the axis of the medical device, e.g., for more accurately measuring the length of objects within the field of view, or oriented at an angle parallel to the axis of the medical device portion, e.g., for more accurately measuring the diameter of the channel (e.g., blood vessel) in which the medical device is disposed.

Methods and systems for controlling an imaging procedure are provided. A medical device is introduced within a patient, and a position (e.g., location and / or orientation) of the medical device is detected within the patient relative to a reference position (e.g., a previously detected position of the medical device or a position within a desired path).

A method corrects thermal displacement of a machine tool having a rotational spindle. The method includes detecting a rotation speed of the spindle. A thermal displacement amount of the spindle in the current cycle of execution of a program is estimated by using an arithmetic expression that is based at least on the spindle rotation speed and a thermal displacement amount that has been estimated in the preceding cycle of execution of the program.
