Abstract
Official abstract text for this publication.
A robot system includes: a robot that is movable according to an external force applied thereto by a worker; a force detecting unit that is provided in the robot and that detects the magnitude of an external force acting on the robot; a warning part that vibrates the robot when an external force having a magnitude equal to or greater than a first predetermined threshold is detected by the force detecting unit; and a stop part that stops the robot when an external force having a magnitude equal to or greater than a second predetermined threshold that is greater than the first predetermined threshold is detected by the force detecting unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A robot system comprising: a robot that is movable according to an external force applied thereto by a worker; a force detecting unit that is provided in the robot and that detects the magnitude of an external force acting on the robot; a warning part that vibrates the robot when an external force having a magnitude equal to or greater than a first predetermined threshold is detected by the force detecting unit; and a stop part that stops the robot when an external force having a magnitude equal to or greater than a second predetermined threshold that is greater than the first predetermined threshold is detected by the force detecting unit, wherein the warning part changes the vibration according to the magnitude of the external force. 2. The robot system according to claim 1 , wherein the force detecting unit detects the direction of the external force; and the warning part makes the vibration different depending on the direction of the external force. 3. A robot system comprising: a robot that is movable according to an external force applied thereto by a worker; a force detecting unit that is provided in the robot and that detects the magnitude and the direction of an external force acting on the robot; a warning part that issues a warning when an external force having a magnitude equal to or greater than a first predetermined threshold is detected by the force detecting unit; and a stop part that stops the robot when an external force having a magnitude equal to or greater than a second predetermined threshold that is greater than the first predetermined threshold is detected by the force detecting unit, wherein the warning part issues a different warning depending on the direction of the external force detected by the force detecting unit. 4. A robot system comprising: a robot that is movable according to an external force applied thereto by a worker; a force detecting unit that is provided in the robot and that detects the magnitude of an external force acting on the robot; a vibration part that is provided in at least one of an arm of the robot and a base on which the robot is placed, and that produces vibration; a warning part that generates vibration in vibration part the robot when an external force having a magnitude equal to or greater than a first predetermined threshold is detected by the force detecting unit; and a stop part that stops the robot when an external force having a magnitude equal to or greater than a second predetermined threshold that is greater than the first predetermined threshold is detected by the force detecting unit. 5. The robot system according to claim 4 , wherein the force detecting unit detects the direction of the external force; and the warning part makes the vibration different depending on the direction of the external force. 6. The robot system according to claim 4 , wherein the warning part changes the vibration according to the magnitude of the external force.
