  • Patent number: 10500724
    Abstract: A teaching device is provided with a trajectory generating unit which generates a robot trajectory based on a start point and an end point, a determination unit which determines the advance direction of an operation tool with respect to a workpiece, and a correction unit which corrects the robot trajectory. The determination unit determines whether or not the advance direction of the operation tool is a predetermined direction with respect to the rotational direction of a tool. The correction unit corrects the robot trajectory by replacing the start point and the end point with each other when the advance direction of the operation tool is different from the predetermined direction.

The interference calculation apparatus includes an operation range setting part configured to judge a position at which the robot can operate without interfering with a peripheral object and set the operable range. The operation range setting part calculates the operable range during a period when the robot is stopped. The interference calculation apparatus calculates an operation allowable range in a direction in which the robot operates based on the operable range. The robot control apparatus executes control for reducing a speed of the robot when the operation allowable range is smaller than a predetermined judgement value.
