However, the rovers cannot just look around them, process the images and know where to go. Neither can the mission controllers on Earth grab a joystick and start steering the rovers whilst watching images being beamed back from thousands of miles away. A key reason is processing power. The central processor in each rover has a top speed of 20 MHz. Instead, during the Martian night, while a rover is 'asleep', a team on Earth with much more powerful computers programs its activities for the day ahead, and then sends basic instructions on where to go and how to get there. Along with taking pictures, each rover is examining the planet with several instruments on a robotic arm. The arms have 'shoulder', 'elbow' and 'wrist' joints for manoeuvrability and are equipped with four sensors: a microscopic camera for close up pictures of rocks, an alpha particle x ray spectrometer for determining the mineral content of rocks, another spectrometer for detecting iron and a rock abrasion tool for cutting through the layer of oxidation that forms on the surfaces of Martian rocks. As with the movement of the rovers, the arms are controlled mostly via prepared commands from mission control. Some observers have noted that some of these applications may prove useful here on Earth. For example, a robotic arm that doesn't require real time human control might be good for disabled people who use wheelchairs and can't control a joystick with their hands. Using its own sensors, it could reach out and get things for the person in the wheelchair, for example. In addition, a robot that can deal with new and unknown environments might save manufacturers money. In current factories with 'robotic' workers, when the company shifts to making a new product, the whole factory floor has to be reconfigured and the robots reprogrammed to deal with the new arrangement. A robot that could use feedback from sensors to figure out where things are could adapt to changes by itself, saving the company the time and effort of building a new structured environment and reprogramming the robots. With all the emerging technologies around and, inevitably, with more to come, the inevitable hurdle will be one of convergence and integration as the IT industry seeks to develop the tools that will be most sought after. Inevitably, there will be winners and losers. However, there is no doubt that the wireless phenomenon is reshaping enterprise connectivity worldwide and is definitely here to stay. Business needs information mobility for better customer interaction.
