A kinematic support structure of a "groove - groove - groove" type that reduces friction between a first base and a second base is provided. In a kinematic support structure (100), a first base (110) comprises three grooves (111, 112, 113) and a second base (120) comprises three other grooves (121, 122, 123). Balls (130, 140, 150) are all movable with respect to the first base (110) and the second base (120). Two grooves corresponding in the two bases face each other across respective one of the balls. |
