Software agents are intelligent systems that pursue goals for their human owners. An example would be an information locator that receives some objectives from its owner, interacts with electronic information sources, locates the desired information, organizes and prioritizes it, and ﬁnally presents it to the owner. Software agents exist in a virtual computer world and their sensors and actuators are distributed among the computer systems with which they interact. They may 18 1 Introduction Agent Specific Attributes • Purpose • Domain of expertise • Nature of sensors and actuators • Mobility • Physical or virtual • How domain is divided between agents • How agents negotiate and cooperate • Degree of cooperation • Degree of individual identity Robots Physical Mobile Agents Software Agents Immobots Distributed Sensors and Actuators Fig.
Second, the science community generally has insisted that all the science data be brought to the ground. , sometimes years after the data were originally collected. Given the science customers’ strong views on this subject, independent of potential future advances in radiation hardened processing capabilities, it would be ill-advised to devise a mission concept that relies exclusively on such onboard autonomy features. A more appropriate approach would be to oﬀer these features as options to users, thereby allowing them to take advantage of cost-saving opportunities as they deem appropriate.
Some sensors require complex processing and in many situations, the information is diﬃcult to interpret. A vision system using even an oﬀ-the-shelf charge-coupled device (CCD) array can easily supply millions of bytes of image data every second. Image processing techniques must be used to examine the data and determine the features of the image relevant to the robot control system. Actuators are used to make changes in the physical world. Examples are opening a valve, moving a wheel, or ﬁring an engine.
