Abstract:
A haptic device (100) configured to be used as man-machine interface for interactions in virtual and/or real places, tele-operation and rehabilitation assisted by robot comprises a mobile unit (1) configured to be interfaced with at least one user (3), a control unit (4) associated with the mobile unit (1 ) and a feeding unit (10). In particular, the mobile unit (1 ) comprises at least three wheels (13) rotationally spaced from each other; each wheels (13) comprises a rotation axis (13') and has a wheel motor unit (1 1) independent, such that each wheel motor unit (1 1) allows the rotation of each wheel (13) about the respective rotation axis (13') in a rotation plane orthogonal to the rotation axis (13'). In addition, each wheel (13) has sliding means (21 ) in a direction transversal to the rotation support plane, such that the mobile unit (1 ) can follow any trajectory. In particular, the sliding means comprises a plurality of rollers (21) arranged adjacent to each other on a same row. This way, each wheel (13) can carry out a "leeway motion" transversally to each wheel rotation plane by the resulting rolling applied by the respective motor units (1 1 ) to the other wheels (13). In particular, in case of three wheels (13) of the mobile unit (1), if a first wheel it has not momentarily a rolling movement, giving to the other two wheels (13) an identical rolling speed, is obtained a translating the first wheel orthogonally to each wheel rotation plane i.e. parallel to its own rotation axis (13'). Giving instead different speeds to the other two wheels (13), it is possible to obtain a movement in a direction oblique with respect to the rotation plane of the first wheel.
Abstract:
An apparatus for the self-feeding of disabled or elderly people comprising: a support base (1; 101a; 101b) ; holding means (9) for an open food container, pivotally connected to the base; means (7) for scooping food from said container; means for moving the scooping means from a food scooping position from the container and a food dispensing position at an height from the base corresponding to the user's mouth, comprising a first arm (3) slantingly extending from the base and a second arm (5) , arranged in a substantially horizontal position and slidably mounted on the first arm (3) , the food scooping means (7) being slidably mounted on the second arm (5) . Motor means (18, 24) are further provided for sliding the second arm (5) along the first arm (3) and the food scooping means (7) along the second arm (5) and for rotating the food container holding means (9) . At least a tank (105) for liquid o semi liquid food and for beverages is placed on the base (1) and means for conveying the food (10, 104) from the tank to the user's mouth are provided; The apparatus also comprises programming and control means of the functions thereof including a mouth operable control (11) placed at the outlet end of the conveying means (10, 104).
