Abstract:
A transportation assembly for transportation of an object on a surface comprises at least four rolling devices, a transportation body and at least one interface element for each rolling device. The interface element is adapted for connecting the rolling device to the transportation body. The interface element for mounting or integration of a rolling device to/into an object comprises an upper part and a lower part, where the upper part and the lower part comprise complimentary shaped guiding means.
Abstract:
A rolling device for a device that is to be moved along a surface is described. The rolling device comprises a cylinder with an opening at one end and a piston that is arranged reciprocally movably in the cylinder such that the piston can be moved between an upper position in the cylinder and a lower position in the cylinder. The piston comprises a rolling element that is arranged in a first end portion of the piston that faces the cylinder opening and that rolls on the surface when the device is to be moved. The rolling device further comprises an actuator system for movement of the piston between the upper position and the lower position in the cylinder.
Abstract:
An adjustable transportation body for transportation on a surface comprises a frame with at least four side beams forming a rectangle and at least four rolling devices connected to the transportation body. Each side beam comprises at least two telescoping elements slidable relative one another between a retracted position and an extended position and an actuator unit configured to cause the at least two telescoping elements to slide relative one another based on the input from a user device.
Abstract:
A transportation arrangement for transportation of an object on a surface comprises at least one transportation unit. The transportation unit comprises a housing comprising a vertical front surface, two arms movably connected to the housing at each side of the vertical front surface, at least one rolling element arranged at a lower portion of the housing, and a power source connected to the rolling elements and the movable arms. The rolling element are configured to roll in any horizontal direction on the surface.
Abstract:
A stabilizing device for a piece of furniture including a housing with a piston opening, and a piston element mounted movably within the housing and moveable at least partly out of the piston opening for engagement with a supporting surface. The stabilizing device further includes an actuator, including a motor, connected to the piston element for actuating a movement of the piston. A control unit connected to the actuator for control of the actuation of the piston element, and at least one first sensor capable of measuring the load on the motor. The at least one first sensor device is connected to the control unit such that the movement of the piston element can be controlled based on input from the first sensor.
Abstract:
A rolling arrangement and a method enable autonomous movement of a device from a first position to a second position along a surface when the rolling arrangement is integrated in the device. The rolling arrangement includes a wireless receiver, a control device, a position acquirer, a driver for driving a rolling element, and a power supply for providing power to the wireless receiver, the control device, the position acquirer, and the driver.
Abstract:
The invention describes a mecanum wheel comprising a plurality of rollers each with a rolling surface and an axel and a wheel frame for mounting the rollers with mounting units holding respective axel ends of each roller. Each mounting unit comprise a mounting unit recess with an opening, wherein the mounting unit recess interacts with the respective axel end for locking the roller against movements in directions having a component radially inwards. Each mounting unit further comprise a rebounding roller retaining structure positioned at least partly inside an insertion path causing resistance when the axel end is pushed or pulled past the roller retaining structure into, and out from, a resting position in the mounting unit recess, thus preventing unintended release in a radial outward directed component.
Abstract:
Rolling device comprising a housing (11) accommodating a rolling element and a control and communication module comprising a wireless receiver (30) connected to a control device (40) and position means (50) connected to the control device, wherein the rolling device further comprises driving means (60) connected to the control device and the rolling element for driving and controlling the movements of the rolling element according to a first position acquired by the position means and a received wireless signal comprising movement instructions and a second position, power supply means (70) for powering the control and communication module and the driving means, wherein the housing is arranged with an support assembly for bearing the rolling element which is configured for establishing a releasable connection with the housing, and an electrical interface adapted for establishing connection between the rolling element and the control and communication module and the power supply means.
Abstract:
A method, system and computer program for updating a position of a remotely controlled rolling device operating in an area together with a plurality of other identical remotely controlled rolling devices, the rolling devices comprises a housing with a rolling element arranged at a first end portion of the housing and where the other end of the housing is inserted into an object to become integrated with the object such that the object is made remotely controllable and movable when the rolling element is in contact with a surface; communication means, control device, sensors and position detection means, driving means 60 and power supply, all of which are connected to each other and installed in the housing. The system comprises a plurality of said rolling devices; and an access point connected to a database server configured to update and calibrate positions of rolling devices.
Abstract:
