57. DEK 3113 When PB is pressed, the robot hand move downwards until it detect by down sensor. Then, the gripper start to grip the “Load” until it is detected by grip sensor. After that, robot hand move upwards until it is detected by up sensor. Then, it move towards right until it reach the most right position as shown in Figure 2 above. After that, the robot hand move downward until it detect by down sensor. Then, the gripper start to ungrip (release) the load until it detect by ungrip sensor. Then, it move upwards until it detect by up sensor. Finally, the robot hand will moves to its original position (most left position). Cartesian Robot as shown above is used to transfer “Load” from point A to point C. It uses 3 different cylinders: Double Acting Cylinder (5/2 way valve) : Move down (activate Y1) and up robot hand (activate Y2). Single Acting Cylinder (3/2 way valve NC): Grip (activate Y3) and ungrip the load. Single Acting Cylinder (3/2 way valve NC): Move right (active Y4) and left robot hands.
