Abstract
A horizontal multi-joint robot includes: a first joint capable of swiveling around a first axis; a second joint capable of swiveling around a second axis that is parallel to and spaced apart from the first axis; and a duct connected between the first joint and the second joint. The first joint has a first connecting portion forming a predetermined angle relative to the first axis. The second joint has a second connecting portion forming a predetermined angle relative to the second axis. The duct has a first end and a second end. The first end is connected to the first connecting portion. The second end is connected to the second connecting portion.

A horizontal multi-joint robot comprising:
- a first joint that is rotatable around a first axis;
- a second joint that is rotatable around a second axis, the second axis being parallel to and spaced apart from the first axis;
- and
- a duct connected between the first joint and the second joint;
- wherein the first joint has a first connecting portion positioned at a first predetermined angle relative to the first axis,
- the second joint has a second connecting portion positioned at a second predetermined angle relative to the second axis, and
- the duct has a first end and a second end, the first end being connected to the first connecting portion, and the second end being connected to the second connecting portion.
A robot comprising:
- a pedestal;
- a first arm connected to the pedestal and being rotatable around a first axis relative to the pedestal;
- a second arm connected to the first arm and being rotatable around a second axis that is parallel to and spaced apart from the first axis;
- and
- a wiring section which accommodates a wire therein, the wire extending from the second arm to the pedestal,
- wherein the wiring section includes:
- a duct supporting portion that protrudes from the pedestal and intersects the first axis;
- a first joint connected to the duct supporting portion and being rotatable around the first axis relative to the duct supporting portion;
- a second joint connected to the second arm and being rotatable around the second axis relative to the second arm;
- and
- a duct connected between the first joint and the second joint,
- wherein the first joint has a first connecting portion located at a first predetermined angle relative to the first axis,
- the second joint has a second connecting portion located at a second predetermined angle relative to the second axis, and
- the duct has a first end and a second end, the first end being connected to the first connecting portion, and the second end being connected to the second connecting portion.
A robot comprising:
- a pedestal;
- a first arm rotatably connected to the pedestal about a first axis;
- a second arm rotatably connected to the first arm about a second axis parallel to and spaced apart from the first axis;
- and
- a wiring section accommodating a wire therein that extends from the second arm to the pedestal,
- wherein the wiring section includes:
- a duct supporting portion protruding from the pedestal;
- a first joint connected to the duct supporting portion and being rotatable around the first axis relative to the duct supporting portion;
- a second joint connected to the second arm and being rotatable around the second axis relative to the second arm;
- and
- a duct connected between the first joint and the second joint,
- wherein the first joint has a first connecting portion inclined relative to the first axis,
- the second joint has a second connecting portion inclined relative to the second axis, and
- the duct has a first end connected to the first connecting portion, and a second end connected to the second connecting portion.
