US 9,751,360 B2 · Bidirectional movement assembly

Abstract

The present invention relates to motor assisted movement as well as to mobile X-ray systems comprising at least one bidirectional wheel. Positioning heavy objects in in particular confined spaces with high precision may be a cumbersome and tedious task. Consequently, a motor assisted movement assembly as well as an X-ray system comprising at least one bidirectional wheel is presented. According to the present invention a motor assisted movement assembly (19) comprising at least one bidirectional wheel (18) and a motor arrangement associated with the at least one bidirectional wheel (18) is provided. The motor assisted movement assembly (19) is adapted to move on a surface, wherein the at least one bidirectional wheel (18) is adapted to roll in at least a first direction (20) and in at least a second direction (22), with the first direction (20) and the second direction (22) being non-parallel. The motor assisted movement assembly (19) is adapted to detect an indication of a desired movement (16) of the motor assisted movement assembly (19) relative to the surface and the motor arrangement is adapted to assist the movement of the motor assisted movement assembly (19) relative to the surface in accordance with the indication (16).

Dependent claims

A motor assisted movement assembly configured for, on a surface, moving in response to an external force applied to said assembly, said assembly comprising:

a bidirectional wheel;
and
a motor arrangement associated with said wheel;
the motor assisted movement assembly being further configured for, via said wheel, the moving on said surface, said wheel being configured for, without need for pivoting said wheel as to rolling direction on said surface, rolling on said surface in a first direction and on said surface in a second direction different from and non-opposite to said first direction;
and,
communicatively connected to said wheel, a control element configured for the responding, said responding including detecting application of said external force and assisting movement of said assembly, said assisting comprising applying, via said motor arrangement, additional force in at least one of said first and said second directions so as to at least partly decrease at least one of perceived moving resistance, and perceived moving force, of said assembly.
