Information-efficient robotic control Academic Article uri icon


  • The work demonstrates a new approach to design of a level of intelligent control of robotic systems. The analytical model results in operational decisions. The structure of these decisions make them readily available to be implemented as an expert system. The approach is applied to a case study of mobile supervisory robots.The model presented here was motivated by manufacturing robotic systems and a type of autonomous robots that collect information at different sites for safety and other control purposes.The robot actions are directly affected by the obtained data. At each site the amount of available information (and thus the correctness of the robot decision) can be increased if the robot keeps collecting data at the site for a longer period of time. This means a delay in reacting and in reaching next site and accordingly, a decrease in the general amount of robot's information on the whole system. The method of finding an economic amount of information collected by a robot at each site is based on the theory of controlled discrete event stochastic systems developed in our earlier works. This theory combines the basic concepts of discrete event control extended to stochastic systems with some aspects of information economics.
