An important goal in navigation of low cost robots is low memory usage. In this paper, we propose a novel navigation algorithm (NafisNav) suitable for embedded systems with low resources, mainly memory. The proposed path finding algorithm is designed and implemented in grid maps. Unlike existing algorithms, that mainly focus on obtaining the shortest possible path for navigation, the proposed algorithm focuses on reducing memory consumption, even at the cost of not always obtaining the best path. Experimental results show the trade-off between path length and memory consumption that is obtained, comparing it with typical algorithms such as Dijkstra or A*.
