Abstract

A robot includes: a robot body including a plurality of joints, and a cleaning mechanism provided to the robot body and configured to clean a predetermined cleaning target site of the robot body to which a foreign material is likely to adhere.

First claim

The invention claimed is:

1. A robot comprising:
an arm having a plurality of joints;
a vertical articulated robot body including an arm having a plurality of joints and an end effector detachably attached to a tip of the arm;
a cleaning mechanism provided in the robot body and configured to clean a predetermined cleaning target site of the arm to which a foreign material is likely to adhere;
a control unit configured to control the robot body;
wherein the cleaning mechanism includes an injection port provided on the end effector attached to a tip part of the arm of the robot body or a tip of the arm and configured to inject the cleaning fluid; and
wherein the control unit comprises a central processing unit configured to execute an operating program for controlling the robot body so that the injection port points to at least one of the joints as the predetermined cleaning target site.

2. The robot according to claim 1 , wherein the cleaning mechanism further includes an injection port provided near the predetermined cleaning target site and configured to inject the cleaning fluid toward the predetermined cleaning target site.

3. The robot according to claim 1 , wherein the predetermined cleaning target site is an oil seal provided to the joint.
