he most basic robot designs just a step up from motorized toys use a wired control box on which you flip switches to move the robot around the room or activate the motors in the robotic arm and hand. The wire link can be a nuisance and acts as a tether preventing your robot from freely navigating through the room. You can cut this physical umbilical cord and replace it with a fully electronic one by using a remote control receiver and transmitter. This chapter details several popular ways to achieve links between you and your robot. You can use the remote controller to activate all of the robot s functions, or, with a suitable on-board computer working as an electronic recorder, you can use the controller as a teaching pendant. You manually program the robot through a series of steps and routines, then play it back under the direction of the computer. Some remote control systems even let you connect your personal computer to your robot. You type on the keyboard, or use a joystick for control, and the invisible link does the rest.

plus or used Atari video game joysticks and even the ones that are available are generally in poor shape because the plastic boot often cracked or pulled out of the plastic base, making the joystick difficult to use. What should be readily available are PC joysticks or gamepads, which can be easily adapted into wired controllers for robots. The PC joystick connects to a PC via a 15 pin D-shell connector and is wired according to Fig. 16-1. The pinout of the PC port is given in Table 16-1 and it can accommodate up to two joysticks. For robot applications in which the joystick will be used to control the motion of the robot, only Joystick A along with its two fire buttons are used. For more complex robots, two joysticks could be wired into the port. The joystick isn t a terrible interface, although it can be difficult to work precisely. Despite the added capability of proportional joysticks, games quickly standardized on a gamepad similar to that used by Nintendo with a cross joystick that was digital (indicates Up, Down, Left, or Right). To interface the gamepad digital joystick with the standard PC game port, the circuit shown in Fig. 16-2 was developed. When the joystick is centered, current flows through one 50k resistor, which is the same resistance as when the analog joystick is centered. If the Right or Down button is pressed, the PNP transistor is turned off and current flows through a second 50k resistor, providing the full 100k resistance of the standard joystick. Finally, if the Left or Up button is pressed, the resistance drops to zero. This circuit works quite well and gives the PC the same interface as a basic game machine. To demonstrate the operation of a gamepad (or an old PC joystick) and turn on an LED according to whether the joystick is moved to an extreme, the circuit in Fig. 16-3 (and parts
