| 摘要 |
The present invention concerns a 3-DOF parallel manipulator (parallel manipulator with three degrees of freedom) comprising a fixed frame (3), three legs (6, 7, 9) of variable length connected to the frame (3), movement means (14) that control the elongation and shortening of said legs (6, 7, 9), a moving platform (8) on which the three legs (6, 7, 9) converge to ensure translation movement in a workspace volume of the platform (8), joints (10, 11) for the connection of the legs (6, 7, 9) to the frame (3) and to the moving platform (8). The joints (10, 11) are positioned so that the three legs (6, 7, 9) are orthogonal to each other in at least one point of the workspace volume of the platform (8). <IMAGE> |
