A vehicle (2) is provided for use for movement across a surface (18). The vehicle (2) includes a body (4), steering means to allow the selective steering of the vehicle (2) via first and second sets of a plurality of drive wheels (11, 12), a first set (11) mounted on one side (14) of the body (4) and a second set (12) mounted on the opposing side (16) of the body (4) so as to contact with the surface (18). At least one wheel in each set (11; 12) is provided so as to be in greater traction and/or grip with the said surface (18) than the other wheels (11; 12) in the set (12) to thereby achieve an improved steering system which requires low power consumption to achieve the steering and thereby reduce the power demand on the batteries of the vehicle (2) which are provided to drive the vehicle (2) and prolong the time of usage of the vehicle (2) between battery charging being required.

Provided is a moving body. A control device of the moving body starts a first control processing that moves a movement part so that a posture of a base with respect to a passenger seat becomes a predetermined posture with an auxiliary grounding part lowered and grounded. The control device starts a second control processing that lifts the auxiliary grounding part with respect to the base and a third control processing that moves the movement part 2 so as to stabilize a posture of the passenger seat after a delay from the start of the first control processing.

Disclosed are a chassis of an automated guided vehicle and an automated guided vehicle. The chassis includes a front frame (1) and a rear frame (2) that are engaged with each other in a hinged joint manner, so as to allow a relative folding between the rear frame (2) and the front frame (1). The relative folding enables the driving wheels and the driven wheels to touch the ground on a sunken road at the same time to prevent that only the driven wheels (10) touch the ground while the driving wheels (9) slip, and increases the approach angle of the chassis on a convex road to prevent the front end of the chassis from touching any obstacle, which improve the safety of the vehicle. Moreover, the damping device (3) restricts the folding angle of the front frame (1) and the rear frame (2) to prevent that the relative folding angle of the front frame (1) and the rear frame (2) is too large to realize the transport function, and damps the folding angle for reducing vibration.

A robotic system and method having a movable and adjustable platform with a plurality of vertically-adjustable legs depending from the platform, the legs having wheels for moving and turning, and a plurality of sensors incorporated with a 3-D model program and movement algorithm that utilizes the information and data collected by the sensors for directing the motors and controls units to move and adjust the robotic system and the system device provided herein.

A robot is provided. The robot includes a lower module includes a wheel and a motor provided inside the lower module, and an upper module disposed at an upper portion of the lower module and including a trash can assembly and a display unit. The upper module includes a body part coupled to the upper portion of the lower module and a head part rotatably coupled to an upper portion of the body part. The body part includes a front case forming a front outer appearance of the body part and including the trash can assembly provided inside the front case, and a rear case forming a rear outer appearance of the body part and including the display unit.

A suspension damping device installed at a chassis of a mobile robot comprises a vehicle frame, a controlling arm set and a damping device. The vehicle frame is fixed to the chassis and arranged on the ground. One end of the controlling arm set is hinged to the vehicle frame, and the other end of the controlling arm set is hinged to a steering device, so the controlling arm set controls the motion stability of the steering device. One end of the damping device opposite to the ground is hinged to the vehicle frame, and the other end of the damping device faced to the ground is hinged to the steering device. A six-wheeled bionic chassis which comprises a chassis frame, a controller, a sensor, front wheel suspension assemblies, middle wheel suspension assemblies and rear wheel suspension assemblies is also disclosed in the present invention.

A mobile elevating work platform includes a chassis and fixed wheels, caster wheels, and a driving and steering wheel secured to the chassis. A control implement coupled with the driving and steering wheel is configured to adjust a steering position of the driving and steering wheel. A drive motor is operable to drive the driving and steering wheel. A platform may be raisable and lowerable with a mast assembly. The control implement may be adjustable to accommodate operator physical characteristics.

A trailer assembly for carrying coiled tubing includes a main beam assembly extending from a forward end of the trailer assembly to a rear end of the trailer assembly. The main beam assembly includes a forward portion that extends from the forward end of the trailer assembly, a rear portion that extends to the rear end of the trailer assembly, and a middle portion connected between the forward portion and the rear portion and configured to transfer load to the forward portion and the rear portion.
