In a trace generation device including a trace generation determination unit that outputs a command of trace generation, when a difference of an actual load applied to a bucket and a reference load is equal to or larger than a predetermined value during excavation and a candidate trace generation unit that generates a trace in which a work amount is almost constant, after the command is output, the reference load is an estimated load and the command of the trace generation is output when the difference of the actual load and the estimated load is equal to or larger than the predetermined value during the excavation. As a result, working efficiency can be raised while a trace in which an excavation amount is almost constant is generated.

Provided is a remotely operated manipulator which can be applied to a space which is wider on a back side than at an opening part, which has a simple structure, high stiffness, and high reliability. The remotely operated manipulator of the present invention includes: a circular base fixed to a wall surface; a beam which rotates on the circular base; a trolley which moves on the beam; and a mast which is raised and lowered with respect to the trolley and is mounted with a tool unit at a tip. Stiffness is improved by directly fixing the beam to the wall surface by a beam fixing device. Further, a work region is expanded by mounting a bending mast on the tip of the mast.

Autonomous mobile equipment includes a position-of-object and own position detecting system and a moving unit, and autonomously moves. The position-of-object and own position detecting system includes a database in which pieces of information on the superficial shape and position of an object are recorded. The superficial shape of the object detected by a position measuring unit is collated with the superficial shape of the object recorded in the database. If the collated superficial shapes agree with each other, the pieces of information on the object recorded in the database are transmitted to a traveling planning unit. If the collated superficial shapes disagree with each other, the information on the object acquired by the position measuring unit is transmitted to the traveling planning unit.

A mobile robot has a mobile mechanism, a swing mechanism and a control unit. The mobile mechanism is of a coaxial two-wheeled type and controls a forward thrust using inverted pendulum control. The swing mechanism actively swings an upper body laterally with respect to the mobile mechanism. A centrifugal force and a gravitational force act on a center of gravity of the mobile robot. A swing attitude is controlled such that a location of intersection of an extension of a composite vector of the forces acting on the center of gravity of the mobile robot and a ground plane of wheels is kept between left and right wheels.

In cleaning using a self-propelled cleaning device, firstly the cleaning device moves alongside a wall surface and then a reference direction is set. Next, the cleaning device advances alongside the wall surface at a prescribed distance, makes a right-angle turn, and travels in the reference direction. When the cleaning device reaches the surface of an opposing wall, it moves in a spiraling manner. At that time, the orientation angle of the cleaning device, which is estimated using a gyro sensor, is checked and corrected. If an obstacle is encountered while traveling, the cleaning device travels on a path that avoids the obstacle or travels in a spiral manner in a region in front of the obstacle.

Self-propelled cleaning device and method of operation thereof

A self-propelled cleaning device having a cylindrical side cover has a suction body capable of moving transversely to the forward direction. The side cover is held by a base via a suspension. When cleaning corners of a room, the suction body moves by a wall and as the suction body moves to a corner, the movement amount of the suction body is changed. When an obstacle touches the cleaning device, the side cover moves, and the article touches a side cover switch, and the direction of the article is detected.

An environment recognition system recognizes a substance moving in relative thereto, with using a modulated beam. A beam emitting means emits a beam. A beam scanning means scans the beam. A beam receiving means detects the beam reflected from the substance. Upon basis of the signal received by the beam receiving means, a distance measuring means obtains a distance image. Comparing plural numbers of the images obtained by the distance measuring means, a distortion removal means removes distortion of the substance contained within the distance image.
