Introduction
Autonomous Navigation robots are used in
multiple sectors for assisting people and to improve
efficiency in completing tasks. There are
many methods for a robot to navigate around
obstacles, however the complexity of utilising
machine vision and sensors is a major challenge
in achieving autonomous navigation.
Project Brief
The aim of this project is to investigate multiple
navigation methods and to design an autonomous
robot which operates in an indoor environment.
Figure 1 shows the initial design for the robot.
The robot should be able to perform the tasks
listed below:
• Ability to navigate a specific room.
• Recognize predefined verbal commands.
• Obstacle avoidance.
