were given by the Arduino UNO controller to move the robot to go sliding left, sliding right,

turn left, turn right, forward dan backward.

 PS2 Controller

PS2 controller is used as the input to the Arduino UNO. Already-built shield for PS2

is used because the control is much easy to use and more importantly user friendly.

 Pneumatic Cylinder

Seven cylinders are controlled by Arduino UNO to control the mechanism of
gripping, extending, lifting and throwing. The operating voltage for each 5/2 valve solenoid

is 24 V. Therefore, there is a need to develop an interface circuit between Arduino UNO
and solenoid valve. Figure 4 shows the interfacing schematic circuit of ULN2803.
