A Review on Challenges of Autonomous Mobile Robot and Sensor Fusion Methods

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.

Critical Design and Control Issues of Indoor Autonomous Mobile Robots: A Review

“…A sensor can detect physical changes in the environment and transform the changes into electrical signals that can be used in further procedures. Sensors can be categorized into two broad categories [12]: 1) Proprioceptive or Exteroceptive kinds of sensors 2) Active or Passive sensors A proprioceptive sensor is able to read the internal changes of the robot such as the internal battery voltage and temperature, speed of motors used, acceleration, and net loads on the wheels. Exteroceptive sensors measure aspects of the external environment of the robot.…”

“…The basic inertial sensors are combined as Inertia measurement Units (IMU) comprising various sensors such as accelerometers or acceleration sensors, gyro sensors or gyroscope, and magnetometers [12].…”

“…Locomotion mechanisms are needed in mobile robots for them to move through their environments in order to perform their tasks that can be achieved by properly understanding the kinematics, dynamics, and mechanism of the system [11]. To understand the surrounding of a mobile robot, perception is an important factor that deals with a set of sensors whose data is extracted by the method of cognition to understand the real view of the surrounding environment [9], [12].…”

“…An excellent survey on navigation techniques such as obstacle avoidance and path planning is provided by [18]. Alatise et al [12] discussed the methods, challenges, and scope of sensor-fusion methods in mobile robotics broadly, but did not discuss other aspects of mobile robotics. These papers are focused on specific aspects of mobile robots and do not provide all of the fundamentals that make the mobile robot reliable and controllable.…”

“…One potential solution is to use robotics [ 12 ]. Mobile robot technology has been developed over many years, and has been applied to various industries [ 13 , 14 ]. Most types of these robots use a two-wheeled differential drive method to regulate the direction of the machine.…”
