A drive unit of a robotic vehicle including a top surface having a mounting interface to interchangeably couple with multiple different modular payload structures configured to transport items in a facility, workspace or inventory management environment. The mounting interface is configured to securely engage with a mounting portion of the variety of different payload structures to enable a versatile exchange of the payload structure for different conveyance applications. The drive unit includes an electrical interface to communicatively couple with the modular payload structures. The drive unit is configured to use data communicated via the electrical coupling and interface to identify a type of modular payload structure that is mechanically coupled to the mounting interface and implement a motion profile (e.g., speed and acceleration parameters) associated with the identified modular payload structure.

A stabilizer includes: a stabilizer bar made of a pipe material; and a stabilizer link that couples the stabilizer bar and a suspension device. The stabilizer link includes a ball stud which includes a shaft portion inserted to and fixed in an opening end of the stabilizer bar and a ball portion formed at a leading end of the shaft portion, a housing which rotatably supports the ball portion, and a flexible dust cover which includes one end attached on the housing so as to be unmovable in a ball stud axis direction and the other end attached on at least either of the shaft portion and the stabilizer bar and which seals a space between the housing and the ball stud.

The invention relates to structural components of vehicles, and more particularly to the suspension of both conventional and special vehicles, such as ambulances, baby carriages and wheelchairs. The suspension comprises a quadrangular frame with a pair of arms attached thereto, where the ends of said arms are configured to be connected to the hubs of the respective wheels, and the suspension of the present invention comprises two pairs of armsa pair of identical transverse arms and a pair of identical longitudinal arms with the ends of the longitudinal arms configured to be connected to the hubs of the respective wheels, wherein each arm is rotatably attached by its central zone to the central portion of the corresponding side of a quadrangular frame through rubber-metal joint, wherein the arms contact surfaces are cylindrical, they are adapted for mechanical coupling of arms to each other and are oriented as follows: longitudinal left and right arms have their contact surfaces oriented upwards, while transverse front and back arms have their contact surfaces oriented downwards, contact surfaces of each arm are tangent to the plane extending through the axis of rotation of the arm and are located on one side of it, while each side of the quadrangular frame rests upon the hubs of two wheels through the corresponding arm. Each transverse and longitudinal arm is made as a pair of arms spaced apart and connected by at least one connecting rod, and each such spaced arm has the form of a parallelogram. The invention is based on the objective to provide the suspension, which is more reliable due to lower level of mechanical stresses in the suspension mechanisms, which results from creation of the conditions where the function of the mechanism for changing the direction of rotation is performed by a transverse arm having a length equal to the width of the suspension.

A moving body includes a frame, a pair of right and left first wheels, a pair of right and left second wheels, a pair of right and left first parallel links connecting the first wheels and the second wheels, and a second parallel link connecting the pair of right and left first parallel links. Furthermore, a height changing unit connects the second parallel link and the frame and changes a position of the frame in a height direction with respect to the second parallel link, and a controller controls the height changing unit so as to maintain a height of the frame from a road surface.

A three-wheeled vehicle having a frame with articulated four-link straight line linkage mechanism mounted thereon, said mechanism including lateral arms arranged symmetrically about the axis of symmetry of the vehicle, and also one conditionally front wheel, and two conditionally rear wheels, each having an axis. The articulated four-link straight line linkage mechanism also includes a linear steering mechanism, a T-shaped arm, a short central arm, an O-shaped bracket, a rubber-strand torsion member of the conditionally front wheel, and one rubber-strand torsion member and L-shaped wheel arm per each conditionally rear wheel, which form a rear axle connected to the linear steering mechanism via the T-shaped linkage arm. The result is increased stability when cornering at a speed, and more accurate steering.
