Why Do Some Robots Have Tank Treads?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do some robots have tank treads?

The Big Idea

Tank treads are belts that go around the wheels! They spread the robot's weight over a large area, so it does not sink into soft ground. They also grip rough ground.

A Belt of Grip

Step one: a belt around wheels. A tread is a long belt that loops around the wheels. The robot lays down its own moving road. The belt has bumps that bite into the ground.

Spread Weight

Step two: spread the weight. Treads touch a large area of ground, so the robot's weight is spread out. That helps it stay on top of soft mud or snow.

Climb Over

Step three: climb. The long belt grips rough ground, so a tread robot can climb over steps and rubble. Snow groomers in Canada use treads to drive on deep snow.

A Closer Look

Let's take a closer look! Wheels inside turn the belt around and around. The long belt wraps the whole bottom of the robot. A big contact area spreads the weight. That means more grip and less sinking. Treads are made for soft, bumpy places.

Quick Facts

Quick facts! Bulldozers and tanks use treads too. Snow groomers in Canada are tread machines. Treads grip better but are slower to turn. Keep your hands out of moving belts and wheels.

Think Like a Scientist

Now, think like a scientist! Press a flat hand into a tray of flour or soft clay. Then press only your fingertips. Which one sinks in more? How does it explain why treads help in soft ground?
