The button with the text Close Hand or Open Hand makes it possible to open and close the robot
gripper. Sometimes this button may be grey in which case instead of the gripper the robot has
another tool. If the gripper exists, then we must use the menu choice Extras->Settings->Grip….
In the open window (Fig. 3.9.) we must choose one of closing or opening commands marked
with number from the menu Gripper Control at Teach-In. When the gripper opening/closing
button does not function, we must choose the command with another number.
