Implementation of Mobile Robot Localisation and Path Planning for Navigation in Known Map
Keywords:AMCL, Laser Scanner, Robotics, ROS, SLAM,
AbstractThis paper describes the implementation of a laser scanner to localise a mobile robot in a known map and navigate to a pinpointed location while avoiding any obstacles within the path. The ability to successfully localise itself is a key requirement for any mobile robot. The Turtlebot Create is used as the platform part to test the localisation. The probabilistic localisation method, the Adaptive Monte Carlo Localization (AMCL) technique is used for the purpose. The approach is experimentation driven due to unique and unanticipated challenges present in the environment. As for obstacle avoidance and path planning, the Dynamic Window Approach (DWA) and Dijkstra’s algorithm is used respectively. The implementation is done using Robot Operating System (ROS) framework and thus is reusable in any future projects with both, simulated and real platforms. The experiments were run in CEASTech and UniMAP Solutions, and it was observed that the robot was able to firstly map the two environments, localise itself in the known map and manoeuvre to the pinpointed locations without any collision.
