A control system allows an operator to remotely control the adjustment components of each of the assemblies.

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.

Disclosed is a mobile robot including: at least three wheels; a sensing unit configured to measure a weight of the mobile robot applied to each of the three wheels; a support member connected to at least one of the at least three wheels; a length adjustment member connected to the support member so as to adjust a length of the support member; and a processor control the length adjustment member for effectively controlling a center of mass of a mobile robot. In addition, disclosed are a method implemented by the mobile robot to control a center of mass of the mobile robot, and a non-transitory computer readable storage medium in which a computer program for implementing the method for controlling the center of mass of the mobile robot.

A lawn mower front wheel positioning system that provides adjustment of lateral positioning of a front wheel of the mower. The front wheel positioning system includes a wheel support arm, a wheel support member, and a wheel positioning arm having an adjustable length. The wheel positioning arm having a proximal end that couples to the wheel support member and a distal end that couples to the wheel support arm. A first end of the wheel support arm couples to the front wheel. A second end of the support arm couples to the support member by way of a support arm wheel pivot that defines a wheel pivot axis. The wheel support arm and the front wheel rotate about the wheel pivot axis responsive to adjustment of the length of the wheel positioning arm.

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.

State of the art track width adjustment mechanism fail to support track width adjustment while vehicle is in motion. They also require manual intervention, which causes inconvenience. The disclosure herein generally relates to wheel track adjustment, and, more particularly, to a changeable wheel track mechanism for track width adjustment (referred to as TWA mechanism). The TWA mechanism includes a steer and drive unit, a plurality of links, and a sliding unit. The TWA mechanism allows movement of a wheel in inward and outward directions, causing the track width adjustment. The track width is achieved by changing the wheel position to be at a wider position, or a narrower position, or any intermediate position. The TWA mechanism may be associated with any vehicle for which the track width adjustment is to be achieved.

A jet-powered sled has a body having a control cockpit with control apparatus for an operator to control the jet sled, a set of surface runners adapted to engage a surface upon which the sled is operated, the surface runners removably engaged to spindles coupled to swing arms coupled to the jet sled, and an engine compartment having a jet engine removably mounted in a manner to direct thrust to a rear of the jet sled to propel the jet sled. The jet sled is characterized in that the sled may be adapted specifically to run on water, ice, or snow by installing runners adapted for water, ice, or snow on the spindles of the swing arms.

Load balancing systems and methods, and trailers with components for load balancing across the trailers or portions (e.g., axles, springs, frame portions) thereof are provided herein. Some trailers comprise a frame, a suspension system configured to support the frame on a set of axles comprising a first axle, and wherein the first axle is movably coupled to the frame. Some trailers comprise a frame, a piping system coupled to the frame, and a set of tanks coupled to one another via the piping system. The piping system can comprise a set of pumps configured to pump fluid between the tanks for load balancing.

A link mechanism is provided between a first member and a second member to effect a bending/stretching motion in operative association with a telescopic expanding/contracting motion of the first member and the second member. A supporting mechanism is provided to support, to the link mechanism, a wire having flexibility and connected between a first device on the side of the first member and a second device on the side of the second member. The supporting mechanism fixes the wire to each link member of the link mechanism in position so that the wire is deformed while maintaining its state following a shape of the link mechanism in operative association with the bending/stretching motion of the link mechanism.
