例を第２・図。A telescopic mechanism 12 is mounted on a rotating mechanism 11 that rotates around the Q1 axis.
The extension and contraction mechanism created by the melody is a combination of a pole screw and a pole nut, and linear movement can be performed by rotating either the pole screw or the pole nut. A spiral mechanism 13 is provided next to the telescopic mechanism 12, and the arm connected thereto is provided with a telescopic mechanism 14 similar to the telescopic mechanism 11, and the length of the arm is different. . Similarly, a telescoping mechanism 16 similar to the telescoping mechanism 11.14 is provided after the spiral mechanism 15, and the length of this arm is also varied like the previous arm. The robot of the present invention can realize various motion patterns using the above-mentioned mechanism, and can also perform more flexible control using redundancy. First, Figure 2 shows an example of how the robot of the present invention realizes the shapes of cylindrical coordinates, polar coordinates, and interrow nodes.

As you can see from this diagram, when you try to carry your hand to the workbench, the arm comes into contact with a cylindrical obstacle. Therefore, in the present invention, by extending the arm of the robot, the wrist is brought to the workbench without coming into contact with this cylindrical obstacle. That is, by extending the telescoping mechanisms 111 and 112 as shown in FIG. 6, the hand can be carried to the workbench while avoiding obstacles.
