78 Controls and Indicators
The deadman switch is used as a safety device to ensure that every movement of the arm is
absolutely wanted and controlled by the operator. That is, if the operator is not pressing the
deadman switch while trying to move the arm with the joystick, no movement will occur. With
such a safety feature, an accidental movement of the joystick will not be transmitted to the arm.
Joysticks operate at 45° and 90° angles. As a result, you can perform two functions at the same time;
for example, you can move the arm and the gripper simultaneously.
