Abstract
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.
Claims6
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.
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.
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.
