  • Abstract
    Recently proposed Dynamic Z* heuristic search algorithm enables mobile robots navigating on uneven terrains to replan energy-efficient paths using previous search results whenever an obstacle is encountered. This paper proposes some vital improvements to Dynamic Z* by optimizing the use of previous search results in replanning. Simulation results show that the proposed improvements can significantly reduce the computational cost of replanning in Dynamic Z* while producing equally energy-efficient paths.
