Abstract

A trajectory generation device generates a trajectory of a robot for conveying an object. A path condition acquisition unit acquires path condition information including at least coordinates of a first via point which is a position of a reference point of a suction nozzle of the robot when the suction nozzle comes into contact with the object, and a velocity, an acceleration, and a jerk of the suction nozzle at the first via point. A pressurization distance and coordinate calculation unit calculates coordinates of a second via point which is a position of the reference point when the suction nozzle is pushed into the object, based on the path condition information; and a trajectory generation unit generates the trajectory of the suction nozzle which satisfies the path condition information and reaches an end point from a predetermined start point via the first via point and the second via point.
