A moving robot has at least one surface wave transducer or a transmitter and receiver, to identify defects on or in a surface on which the robot moves, and provide data indicative of the location, size and/or orientation of the defects from robot position data.

A multi-terrain wall climbing vehicle including a generally rectangular housing having a top opening and a bottom opening. A power source is placed within the housing. A first motor and a second motor are located within the housing and are connected to the power source. At least four pairs of wheels are connected to the housing, at least two of the wheel pairs being connected to and powered by the first motor. Two tracks are placed onto the wheels so as to surround the housing to enable the vehicle to ride along a riding surface. A propeller is placed within the housing between the top opening and the bottom opening. The propeller is connected to the second motor. As the propeller rotates, it draws in air from at least one of the top opening and the bottom opening and exhausts the air through the top opening so as to generate an adhesion force enabling a secure connection between the tracks of the vehicle and the riding surface.

A work apparatus that can collect core samples of a seabed ground at a desired angle in a stable manner includes a body 10, four flippers 30 rotatably disposed at left and right of a front section of the body 10 and at left and right of a rear section of the body 10 and a coring mechanism 20 disposed on the body 10 as basic features. An inclination sensor 17 that detects inclinations in a front-rear direction and in a left-right direction is disposed on the body 10. A load sensor 49 is attached to a support structure 40 rotatably supporting the flippers 30. A controller 16 controls rotations of the four flippers 30 based on information on inclination from the inclination sensor 17 and information on landing of the flippers 30 from the load sensor 49 to make the body 10 assume a desired attitude, which is a horizontal attitude, for example, and to land at least three flippers 30. After the attitude control, the controller 16 activates the coring mechanism 20 to collect the core samples from the seabed.

A compact ground robot includes a vehicle body, a forward pair of track assemblies mounted to the vehicle body, and a rearward pair of track assemblies mounted to the vehicle body. All the track assemblies are foldable underneath the vehicle body for compact transport of the robot. All the track assemblies unfold to a deployed position supporting the vehicle body for deployment of the robot. Each track assembly may include a drive sprocket, a flipper, and a tack about the sprocket and flipper.

A mobile robot adapted to traverse vertical obstacles. The robot comprises a frame and at least one wheel positioned in a front section of the robot, at least one middle wheel positioned in a middle section of the robot, at least one back wheel positioned in a back section of the robot, and at least one further wheel in the front, middle or back of the robot. The robot also comprises at least one motor-driven device for exerting a downward and/or upward force on the middle wheel and at least two motors for driving the wheels and the motor-driven device. Also disclosed is a method of climbing using a mobile robot as disclosed.
