Standard Work Envelope

The following "work envelope" diagrams show the model with standard (maximum) specifications. When each joint motor is under servo control, the center of the Manipulator shaft’s lowest point moves in the ranges shown in the figure.

  • Range to mechanical stop
    This is the range where the center of shaft’s lowest point can be moved when each joint motor is not under servo control.
  • Mechanical stop
    This is the stop that sets the absolute work envelope where the Manipulator cannot move beyond mechanically.
  • Maximum zone
    This is the range that contains the farthest reach of the arms where interference can occur. If the maximum radius of the hand exceeds 30 mm, add the "Range to mechanical stop" and the "Radius of the hand." The total value is specified as the maximum zone.
