Wireless computer networks predominantly use a protocol called 802.11, with different variations on the protocol for different speeds. The 802.11x LAN is based on an architecture that is very similar to the design of cellular telephone networks. Wireless LANs (WLANs) operate by connecting an access point to the server (see Figure 2-10), while client computers are fitted with wireless networking cards. These cards can be fitted for either a desktop or laptop computer. Some computers come with wireless capabilities built in.

slice of time where you ve captured the essence of motion, be it an athlete caught in mid-flight while vaulting the pole in a high jump or a batter in mid-swing. If you ve used a film camera to photograph action, you may think you can use the same techniques, and you re almost right. Digital cameras are close to their film-bearing brethren, but digital cameras have to think after you press the shutter button. Therefore, you have to think ahead in order to capture a wonderful action scene, such as the one shown in Figure 5-1, instead of a blurry, unrecognizable image.

your opponent, and your robot s sensors will lock onto the opponent and take over the driving. You maintain complete control of the weapon and let your robot push the opponent around the ring, you can have all the fun smashing its opponent to pieces with its weapon. This type of a system needs at least two range detectors, such as the Sharp GP2D05 or the Devantech SRF04. Place both of these in front of your robot with the detection beams crossing each other. A microcontroller is used to monitor both sensors and to control the motor controllers. With this sensor configuration, the logic for driving the robot is relatively simple. If the left sensor detects the opponent, turn your robot to the right. If the right sensor detects the opponent, turn your robot to the left. If both sensors detect the opponent or both detectors do not detect the opponent, drive forward. You manually drive your robot up to your opponent until it is within your robot s crossing beams reach, and then you can enable the semiautonomous tracking system and your robot will close in on your opponent on its own. Figure 11-7 shows a simplified schematic of this type of control system. As with the semiautonomous weapons system, an active link must exist between the radio receiver and the semiautonomous target-tracking system s microcontroller. If the microcontroller loses contact with the radio receiver, the semiautonomous target-tracking system must shut down and enable manual control of the robot.
