The article is devoted to the analysis of the behavior of a mobile robot using finite state machine algorithms in order to find a way to the goal and avoid obstacles. After justifying the use of such methods, the analysis of a standard deterministic finite automaton is done. Further, the theory of Markov processes is applied to this algorithm, as a result of which the state machine becomes part of the hidden Markov model. This allows you to apply probabilistic methods to modeling the behavior of the robot. This probabilistic behavior is most promising in complex environments with unpredictable obstacle configurations. To compare the efficiency of deterministic and probabilistic finite state machine, we applied a genetic algorithm. In the numerical experiment that we conducted in the Scilab software, we considered two main types of environments in which a mobile robot can move - an office-type environment and a polygonal-type environment. For each type of environment, we alternately applied each of the indicated behavior algorithms. For the genetic algorithm, we used one hundred individuals who were trained over 1000 generations to find the most optimal path in the specified environments. As a result, it was found that the deterministic finite state machine algorithm is the most promising for movement in an office-type environment, and the probabilistic finite state machine algorithm gives the best result in a complex polygonal environment.
Definitions are given and the difference between positive and negative algebra of logic is indicated. It is noted that when switching from positive logic to negative, the elements of "Schaeffer's Stroke" and "Pierce's Arrow" change places. Similarly, conjunction changes with disjunction. The inverter retains its property regardless of its application in positive or negative logic. The laws and rules valid for the negative algebra of logic are presented. The method of transition from the positive algebra of logic to the negative one is presented. Elements of positive and negative logic are compared. On the basis of logic functions: (AᴧBᴧC)ᴧDvAᴧ(BᴧCᴧD)vAᴧ(BᴧC)ᴧDv(AᴧB)ᴧ(CᴧD), implemented by direct optimized, minimal, options matching device, as well as, the final options in bases 2-NOT-OR (2-AND-NOT), 4-NOT-OR (4-AND-NOT) for negative logic. The voltage table of K155LE1, K155LE3 microcircuits is presented. The truth table of K155LE1, K155LE3 microcircuits in negative logic algebra (as an element AND-NOT or NOT-OR) is presented. Truth tables of K176LE5, K176LE6 microcircuits are shown in positive logic algebra (OR-NOT). The voltage table of K176LE5, K176LE6 microcircuits is shown. The truth table of K176LE5, K176LE6 microcircuits is shown in negative logic algebra (as an AND-NOT or NOT-OR element). elements of negative logic. Conclusion about the results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
