A surgical robot a robotic device and a cart. The cart is coupled to the robotic device and includes a steering assembly. The steering assembly includes wheels and is configured such that the wheels allow the cart to roll in a linear direction when a first mode is selected and the wheels allow the cart to roll in a rotational direction when a second mode is selected.

A toolbox apparatus having mobility is disclosed. The mobile toolbox apparatus comprises a toolbox, a platform on which the toolbox is mounted, supporting means provided on the operative bottom surface of the platform, and at least one wheel coupled to at least one supporting means for providing mobility to the mobile toolbox apparatus. The apparatus comprises a handle coupled to the platform, wherein the handle has a telescopic configuration. The apparatus further comprises a platform extension hingeably coupled to the platform.

The present invention discloses a foldable trolley with convenient folding structure, comprising an tipper folding frame, a lower folding frame and a supporting rod assembly. Sliding ends of both the front and rear sliding upright rods slide closely or backwardly as the lower folding frame is folded or expanded, thus to form a triangular support arm structure, thereby strengthening the stability of overall structure. Besides, a folding lock-release mechanism is provided, when the foldable frame is expanded, the front and rear locking assemblies thereof respectively limit the front and rear sliding upright rods to slide; when the foldable frame is folded, the front and rear locking assemblies release limitation of the front and rear sliding upright rods respectively through the unlocking assembly. The foldable frame can be folded by simply lifting the upper connecting rod up, thus one key locking or unlocking is achieved, and the operation is convenient.

A pet stroller includes a stroller frame and an entrance arrangement. The stroller frame includes a foldable frame, a boundary frame supported by the foldable frame, and a handle frame upwardly extended from the foldable frame, wherein the boundary frame includes a U-shaped boundary member defining a pet seating area and a front entrance. The entrance arrangement includes a front entrance member movably coupled at two front ends of the boundary member respectively to move between an uplift position and a drop down position. At the uplift position, the front entrance member is lifted upwardly to form a front boundary of the boundary frame for blocking the front entrance, and at the drop down position, the front entrance member is dropped down to enlarge the front entrance for accessing the pet seating area.

A counterbalanced vertical track assembly which may be configured with three types of pulley support assemblies are herein disclosed. The first type of pulley support assembly has a pair of opposed pulley modules having an elongate structural element interposed the two pulley modules which are attached to end plates at both ends of the elongate structural element. The second type of pulley support assembly has a pair of opposed pulley modules which include male end connectors for demountable engagement of the pulley modules with another module of the system with female ends. The third type of pulley support assembly has a pair of opposed pulley modules wherein the modules' pulley brackets are repositionable to varying angular orientations by alternating screw mount positions selected on mount components at opposite ends of an elongate structural element.
