Abstract:
Autonomous mobile robots are becoming more prominent in recent time because of their
relevance and applications to the world today. Their ability to navigate in an environment without a need
for physical or electro-mechanical guidance devices has made it more promising and useful. The use
of autonomous mobile robots is emerging in different sectors such as companies, industries, hospital,
institutions, agriculture and homes to improve services and daily activities. Due to technology advancement,
the demand for mobile robot has increased due to the task they perform and services they render such
as carrying heavy objects, monitoring, search and rescue missions, etc. Various studies have been carried
out by researchers on the importance of mobile robot, its applications and challenges. This survey paper
unravels the current literatures, the challenges mobile robot is being faced with. A comprehensive study
on devices/sensors and prevalent sensor fusion techniques developed for tackling issues like localization,
estimation and navigation in mobile robot are presented as well in which they are organised according to
relevance, strengths and weaknesses. The study therefore gives good direction for further investigation on
developing methods to deal with the discrepancies faced with autonomous mobile robot.
