E cost worth xy = 200. A threshold of 0.five is employed for the self-confidence level to neglect low self-assurance detections. An area with an adjustable radius about every level to neglect low self-assurance detections. An area with an adjustable radius around each human cell is defined as a human safety zone. The Human layer calculates the Euclidean human cell is defined as a human security zone. The Human layer calculates the Euclidean distance in between the current robot position and each and every human cell to decide when the robot distance amongst the present robot position and every single human cell to determine if the robot is inside a human security zone. Following the idea of thethe navigation zones, robot will is inside a human security zone. Following the concept of navigation zones, the the robot will preventively transform its motion behavior if it really is inside a human zone. Moreover, the preventively alter its motion behavior if it really is inside a human security safety zone. Also, the humaninflated to create ato produce a buffer zone around the human co-workers. human cells are cells are inflated buffer zone around the human co-workers. The radius The radius of these buffer zones is smaller compared tosafety zones. The price value ofcost of those buffer zones is smaller when compared with the human the human safety zones. The the value in the corresponding cells is= 200. = 200. Theoretically, the robot to allowed to corresponding cells is set to 7 set to Theoretically, the robot is permitted is plan close xy planhuman, nevertheless it is highlyit is very price inefficient.

The Lidar information is are converted in to the costmap space to determine the readings. The sensor readings are convided in form of an array , such as the sensorcorresponding cells.
