Difficulty 3/5 · ClassroomWheels and tracks are the two most common locomotion methods for mobile robots. Wheels are simpler, faster, and more efficient on smooth ground; tracks distribute weight, climb obstacles, and grip rough terrain.

Think of it like a household object that does the same job — the underlying idea is the same, just adapted for robots.

Wheels vs Tracks for Robots
What is it?
Wheels and tracks are the two most common locomotion methods for mobile robots. Wheels are simpler, faster, and more efficient on smooth ground; tracks distribute weight, climb obstacles, and grip rough terrain.
How it works
Wheels rely on point contact with the ground, which works perfectly on flat surfaces but struggles in sand, mud, or steps. Tracks have many small contact patches that distribute load over a larger area, allowing the robot to cross loose surfaces and small obstacles. Tracks have higher friction (good for grip, bad for energy).
Real-world example
A Roomba uses two large wheels — perfect for indoor floors. A Mars rover uses six independently driven wheels with rocker-bogie suspension. The DRDO Daksh bomb-disposal robot uses tracks for stair-climbing and uneven outdoor terrain.
Why it matters for robotics
Choosing the right locomotion is one of the first design decisions every robotics team makes. Wrong choice and the robot can't move; right choice and the rest of the design becomes simpler.
