Examples of safety options

Separation of the operator operation area and robot operation.

The operator operation area and robot operation area are separated each other with a monitoring plane for safety.

·         The robot operates at high speed while the safety fence is close.

·         While the safety fence is open, the robot continues its operation at low speed inside the monitoring plane.

·         The operator can perform inspection inside the safety fence and outside the monitoring plane.


Cooperative operation with a robot and an operator.

An operator and a robot access the shared operation area alternately, allowing for cooperative operation with a robot and an operator.

·         While the operator is on the mat, the robot cannot enter the shared operation area.

·         While the operator is not on the mat, the robot operates inside the shared operation area.

Area sensors secure the safety without safety fence.

Area sensors secure the safety without safety fence.

·         When the operator enters the limit area, the robot operation speed is limited.

·         Further, the operator approaches to the stop area, the robot stops its operation.
