FIELD: computer science. ^ SUBSTANCE: lower element of support of leading ball is made in form of flat link of two roller bearings, rotation axes of which are perpendicular and do not intersect, while roller bearing, axis of which is vertical, rotates either inside bushing, held in body of spherical manipulator, or on axis, held in body of spherical manipulator. Smoothness and speed of rotation of leading ball do not depend on its rotation direction and height of device is considerably lowered without decrease of leading ball diameter. ^ EFFECT: lesser dimensions, higher comfort of use. ^ 3 cl, 2 dwg |
