Problems solved by technology

[0004] However, the closer the arm is to the base, the more flexible connecting parts such as electric wires and air piping are accommodated. Therefore, if the manipulator is to be miniaturized, the layout of the parts inside the arm becomes cramped.
In addition, the flexible connecting member accommodated in the arm deforms along with the rotation of the arm. Therefore, it is necessary to enlarge the housing space of the connecting member, and the radius of rotation of the outer peripheral surface of the arm tends to be increased.

Embodiment Construction

[0012] 1. Example

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same code|symbol is attached|subjected to the corresponding component in each figure, and overlapping description is abbreviate|omitted.

[0014] figure 1 , figure 2 , image 3 A robot as an embodiment of the present invention is shown. The robot of this embodiment is a vertical articulated robot including a base 9 and a manipulator including a plurality of arms 1 , 2 , 3 , 4 , 5 , and 6 . Motors for driving the manipulator are housed in the base 9 and the arms 1 , 2 , 3 , 4 , and 5 . The motor 901 provided on the base 9 is an actuator that rotates the first arm 1 around the axis A1 relative to the base 9 . The motor 104 provided on the first arm 1 rotates the second arm 2 around the axis A2 relative to the first arm 1 . A motor (not shown) provided on the second arm 2 rotates the third arm 3 with respect to the second arm 2 ab...

Abstract

The invention provides a robot having less rotational radius of periphery surface of arms. The robot includes a supporting unit (9) that rotatably supports a first passive shaft part (101), and a first arm (1) fixed to the first passive shaft part (101), wherein the first arm (1) has an internal space overlapping with the first passive shaft part (101) in a direction orthogonal to a center shaft of the first passive shaft part (101).

Description

technical field [0001] The present invention relates to robots, and in particular to the construction of manipulators for robots. Background technique [0002] Conventionally, in an articulated robot, there are motors, pulleys, transmission belts, inertial sensors for detecting angular velocity and acceleration, backup circuits for storing the posture of the arms, and batteries for the backup circuits as parts housed in the arms of articulated robots. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2014-46401 [0004] However, the closer the arm is to the base, the more flexible connecting parts such as electric wires and air pipes are accommodated. Therefore, if the manipulator is to be miniaturized, the layout of the parts inside the arm becomes cramped. Furthermore, since the flexible connection member accommodated in the arm deforms as the arm rotates, it is necessary to enlarge the storage space for the connection member, which tends to increase the radius of...
