Hardware Efficient Scheme for Indoor Environment Using Grid Mapping

Abstract

This paper addresses the mobile robot navigation using grid mapping. The proposal is to introduce dedicated Hardware scheme for robot navigation and it is deployed on Spartan 3E FPGA. The environment is divided into the grids, where landmarks are considered as grid points. Landmarks are RFID tags, among RFID system the reader is placed on the robot and interfaced with FPGA using UART protocol. The proposed path planning is also developed with obstacle avoidance mechanism to overcome the obstacles in robust environment. The robot navigation efficacy improves with the landmarks and hardware scheme. The hardware scheme is developed with NI lab view. Simulation and experimental results are furnished for proposed navigation algorithm in our laboratory. Aim: Navigation of FPGA based Autonomous robot efficiently towards the target using grid mapping technique.
