Abstract
An industrial robot with a manipulator arm including at least one manipulator element and an electric motor driving the at least one manipulator element. An energy reservoir supplies the electric motor with electricity when a power failure or power loss occurs to move the manipulator element from a working position to a safe parking position. Also a method of parking a manipulator arm of an industrial robot.
Claims6
1-3. (canceled)
An industrial robot with a manipulator arm, the industrial robot comprising:
- at least one manipulator element;
- an electric motor driving the element;
- an energy reservoir arranged to supply the electric motor with electricity when a power failure or power loss occurs;
- and
- a robot controller comprising a power failure or power loss routine activating the energy reservoir to supply the electric motor with electricity and to move the manipulator element (3) from a working position to a safe parking position.
A method of parking a manipulator arm of an industrial robot in case a power failure/loss is detected, the method comprising:
- detecting a power failure/loss;
- activating a power failure routine or a return to safe parking routine by a detected signal;
- enabling an energy reservoir to supply electric energy to an electric motor to transport the manipulator arm to a safe parking position;
- and
- disabling the energy reservoir from supplying electric energy to said electric motor when the parking is performed.
