The shopping cart security system is configured for use with a hand propelled vehicle known as a shopping cart. The shopping cart security system is a wheeled structure that allows the hand propelled vehicle to roll over a supporting surface. The shopping cart security system: a) determines the GPS coordinates of the shopping cart security system; b) compares the GPS coordinates of the shopping cart security system with a previously determined set of GPS coordinates that determine an operating perimeter for the shopping cart security system; and, c) disables the rotation of the wheeled structure that forms the shopping cart security system when the shopping cart security system is determined to be outside of the region bounded by the previously determined operating perimeter.

A surgical robot includes a robotic arm, a cart supporting the robotic arm and including a steering assembly. The steering assembly comprises wheels and a handle. The handle is moveable to a first position, a second position, and a third position. The steering assembly is configured such that the wheels allow the cart to roll in a longitudinal direction when the handle is in the first position, the wheels allow the cart to be roll a rotational direction when the handle is in the second position, and the wheels allow the cart to roll in a lateral direction when the handle is in the third position.

A vehicle mitigation system a barrier hauler and at least one barrier. The barrier hauler includes a stem, a handle positioned at one end of the stem, and at least one wheel positioned near an opposite end of the stem, the wheel capable of rotating relative to the stem. The barrier hauler further includes a lift arm having an engagement pin, the lift arm rigidly fixed relative to the stem and disposed at a first angle to the stem. The barrier includes at least one wheel positioned at a first end of the barrier to act in cooperation with the at least one wheel of the barrier hauler when the barrier hauler is engaged with the barrier.

Wheel assembly (200) a self-propelling trolley (100), comprising a wheel (111,112); an electric motor (151,152) arranged to perform a rocking drive pattern; an electric connector (220), arranged to connect the motor (151,152) to a battery (156); and a mechanical brake (230) activatable so that a rotational movement of the wheel (111,112) is limited, The invention is characterised in that the mechanical brake (230) is arranged so that, in an engaged state, the wheel (111,112) can turn freely in relation to the trolley (100) across a ground distance of between 5 and 20 cm between a first rotary limit position and a second rotary limit position. The movement limitation is provided by several elongated concentric tracks interacting with a pin.

An apparatus configured to convert between a cart and a lounge chair comprising a bottom portion, backrest portion, a leg rest portion, first and second removable side portions. The backrest and leg rest potions rotatably coupled to the bottom portion and movable between open and upright positions. The first and second removable side portions being coupled to the backrest and leg portions when in the upright positions, wherein an open carton of the cart is formed by the bottom portion and the leg rest and backrest portions when in the upright positions, and the first and second removable side portions when connected to the leg rest and backrest sides, and the leg rest and backrest portions, when in the outward positions, form a seat, a leg rest and a backrest of the lounge chair, respectively, the lounge chair being configured to support a person in a sitting or lounging position.

A surgical robot includes a robotic arm, a cart supporting the robotic arm and including a steering assembly. The steering assembly comprises wheels and a handle. The handle is moveable to a first position, a second position, and a third position. The steering assembly is configured such that the wheels allow the cart to roll in a longitudinal direction when the handle is in the first position, the wheels allow the cart to be roll a rotational direction when the handle is in the second position, and the wheels allow the cart to roll in a lateral direction when the handle is in the third position.

A brake operating arrangement (18) comprises a cam member (22) operable on a brake mechanism (36) for braking a wheel (34). The brake mechanism (36) is movable between a braking condition and a non-braking condition. The cam member (22) is rotatable to move the brake mechanism (36) to the braking condition. The brake operating arrangement (18) further includes a drive member (44) movable in drive and return directions; and a ratchet mechanism (46) to rotate the cam member (22) when the drive member (44) is moved in the drive direction. The ratchet mechanism (46) is connected to the drive member (44) and the cam member (22).

Disclosed herein is a simulated Ghana Christmas hut, in accordance with some embodiments. Accordingly, the simulated Ghana Christmas hut comprises a base structure and huts. Further, the base structure is configured to be disposed on a surface. Further, the huts are supported on the base structure. Further, the huts are stacked on the base structure in a vertical direction based on a hut size of the huts. Further, each hut comprises a side wall and a roof corresponding to the hut size of each hut. Further, the roof is attached to the side wall along a top edge of the side wall for forming a hut interior space. Further, the side wall of each hut comprises an opening leading into the hut interior space of each hut. Further, the side wall and the roof of each hut are comprised of coconut fronds.

A portable surgical robot includes a surgical device and a cart. The surgical device is coupled to the cart. The cart includes a chassis, a mount coupled to the chassis, a carriage pivotally coupled to the mount, and a set of wheels. The carriage includes a first bracket positioned at a first lateral end of the carriage and a second bracket positioned at a second lateral end of the carriage. A first wheel of the set of wheels is coupled to the first bracket and a second wheel of the set of wheels is coupled to the second bracket. The carriage is configured to pivot relative to the mount to prevent at least one of (i) rocking of the portable surgical robot, (ii) fluttering of the first wheel, (iii) fluttering of the second wheel, and (iv) tipping of the portable surgical robot.
