Quadruped robot
사족보행 로봇
A robot that walks on four legs like a dog. It also moves well on stairs and rough ground.
Overview
A robot on wheels is fast on a flat floor but stops in front of stairs or a gravel field. A four-legged robot keeps its balance by placing its feet one at a time, so it can go almost anywhere a person can. It is less likely to fall than a humanoid that walks on two legs.
Carrying a camera and several sensors on its back, it goes around factories and power plants to check equipment, records construction sites, and scouts disaster sites that are too dangerous for people to enter first. Some models have an arm attached to open doors. There are also worries that it could be used to carry weapons.
An everyday example
On a mountain trail, a goat gets around much better than a bicycle. Where wheels cannot go, feet can.
Why it matters
It shows up in the news often under the name "robot dog." Companies that built four-legged robots are now building humanoids on that technology, so it helps you understand the trend in walking robots.
