Robot Guide
Robots are helping hospitals, hotels, warehouses, homes, schools, and businesses perform useful tasks more efficiently. This guide explains the main types of robots, what they do, and how to choose the right robot for your needs.
Some robots clean floors. Others transport items through hospitals, support manufacturing, assist surgeons, interact with people, or provide companionship. With so many different options available, finding the right robot can be difficult.
The best way to begin is to understand the main robot categories and the problems they are designed to solve.
ⓘ Quick Answer
The main types of robots include service robots, industrial robots, medical robots, domestic robots, and companion robots. The right choice depends on the task, environment, level of autonomy, budget, maintenance needs, and local availability.
What Is a Robot?
A robot is a machine designed to perform tasks with a certain level of automation. Depending on its design, a robot may move, sense its environment, process information, communicate with people, or operate tools.
Robots can be:
- Fully autonomous
- Partially autonomous
- Remotely controlled
- Designed for one specific task
- Built to support several different tasks
Not every robot looks human. A robot may be a small desktop companion, a robotic arm, a mobile platform, a quadruped machine, or a household appliance that navigates through your home.
The most important question is not what a robot looks like. The important question is what problem it solves.
