Mobile Robots: Navigating and Operating in Dynamic Environments
Unlike robotic arms that are fixed to a base, mobile robots are machines designed to move and interact with their
environment by changing their physical location. Their ability to navigate autonomously or semi-autonomously allows
them to perform tasks in vast and dynamic spaces, from factory floors and city streets to disaster zones and even
other planets. The fundamental challenge for a mobile robot is to know where it is, where it needs to go, and how to get
there safely without colliding with obstacles.
Basic Design Principles of Mobile Robots
The design of a mobile robot is driven by its intended application and the environment it will operate in. Key design
principles include:
Locomotion System (How it Moves)
This refers to the mechanism that allows the robot to move. The choice of locomotion system greatly influences the
u
robot’s speed, stability, manoeuvrability, and ability to traverse different terrains.
Wheeled Robots
Description
The most common type, using wheels for movement. They are efficient on flat,
hard surfaces.
Variations
Can have two wheels (requiring balancing), three wheels (tripod for stability), or
four/more wheels for better traction and stability. Some use specialized wheels (like
Mecanum wheels) for omnidirectional movement (moving sideways or diagonally
without turning).
Advantages
Energy efficient, simple to control on smooth surfaces, relatively fast.
Disadvantages:
Poor performance on uneven terrain, stairs, or soft surfaces.
Example: Robotic vacuum cleaners, warehouse Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots
u
(AMRs), self-driving cars.
