A caterpillar device includes: a water film removing part which is provided in a power transmission member including chains, presses and removes a water film between an attachment object as a magnetic material, and the power transmission member with a magnetic force, and attaches the power transmission member to the attachment object to secure a frictional force; and an apparatus body magnet attachment part which is connected to the power transmission member and attaches the body of the apparatus to the attachment object.

A remotely controlled packable robot features a chassis, right and left main tracks for maneuvering the chassis, and right and left tracked rotatable flipper arms for maneuvering the chassis. An integrated drive assembly is provided for each main track and flipper pair and includes a motor in a housing attached to the chassis for rotating the flipper and a stator and rotor disposed about the motor housing for driving the main track and the flipper track.

A robotic device for providing vertical mobility has a payload is disposed inside a central compartment and supported by a skid. The skid can move up and down through latch and hook pairs to keep intimate contact with the surface and cross over bumps. The apparatus uses a flexible seal to create a reliable vacuum chamber. The flexible seal comprises a foam ring inside fabric pocket. A plurality of rod and spring strips are configured to apply a downward force to the flexible seal to conform with surface curvatures. The fabric pocket fills in the gaps or seams to maintain a vacuum. The air flows inside a manifold and passes through a filter to avoid debris from damaging the vacuum motor assembly.

A remotely controlled packable robot features a chassis with a top surface and a bottom surface, a pair of main tracks for maneuvering the chassis, and an open channel under the robot defined by the bottom surface of the chassis and the main tracks. A robot arm is foldable from a stored position in the open channel underneath the robot chassis to a deployed position extending upwards from the top surface of the chassis. A camera assembly may be foldable from a stowed position in the open channel underneath the robot chassis next to the robot arm to a deployed position extending upwards from the top surface of the chassis.

The tree climbing robot includes a central body and a pair of track carriers respectively pivotally attached to opposed sides of the central body. A set of wheels is rotatably attached to each of the track carriers, and a continuous track is mounted on, and is driven to rotate by, each set of wheels. At least one motor is mounted on each of the track carriers, such that each motor drives a corresponding one of the sets of wheels and a corresponding one of the continuous tracks to rotate. At least one cable is secured to the central body and is adapted for wrapping around a trunk of a tree. Each of the track carriers is elastically biased with respect to the central body such that the trunk of the tree is clamped between the pair of tracks, with the cable adding securement, stability, and aiding vertical movement.

A wall surface suction-type travel device includes a first travel unit, a second travel unit, a joint mechanism, and an elastic mechanism. The first and second travel units are aligned along a travel direction and are each configured to travel on a wall surface while being suctioned on the wall surface. The joint mechanism couples the first and second travel units together such that the travel units can pivot relative to each other on a pivot axis extending in a direction that is perpendicular both to a wall surface facing direction and the travel direction. The elastic mechanism includes a first end fixed to the first travel unit, a second end fixed to the second travel unit, and an elastic member configured to be elastically deformed when one of the first and second travel units pivots relative to the other travel unit and a distance between the first end and the second end is shortened.
