Quadrupedal robotics has evolved enormously in recent years. What once seemed reserved for research laboratories or large technology companies is now within reach of businesses, educational centers, and development teams looking to explore new forms of automation and artificial intelligence.

Within this sector, the Unitree Go2 series has become one of the most prominent references thanks to its combination of advanced mobility, artificial intelligence, state-of-the-art sensors, and a much more accessible price than other solutions on the market.

However, three main models appear when exploring the range: Unitree Go2 Air, Unitree Go2 Pro, and Unitree Go2 X. Although they share the same technological base, each is designed for very different needs.

In this guide, we analyze their features, differences, and use cases to help you choose the most suitable quadrupedal robot for your project.

What is a quadrupedal robot?

A quadrupedal robot is a mobile robot that moves using four legs, mimicking the locomotion of animals such as dogs, wolves, or horses.

Unlike wheeled robots, quadrupeds can better adapt to uneven terrain, overcome obstacles, climb stairs, and maintain stability in complex environments.

This capability makes them particularly useful tools for applications such as:

• Industrial inspection.

• Research and development.

• Technological education.

• Automation.

• Surveillance and security.

• Artificial intelligence development.

• Exploration of difficult environments.

What makes the Unitree Go2 series special?

The Go2 family incorporates technologies that until recently were only present in very high-cost robots.

Its main features include:

Smart navigation

Thanks to their advanced perception system, robots can autonomously orient themselves and better understand their surroundings.

Integrated 4D LiDAR

The LiDAR system allows for real-time generation of 3D maps of the environment, facilitating navigation and obstacle detection.

Artificial intelligence

Go2 models incorporate AI-powered functions that allow for advanced tasks, spatial recognition, and even interaction via voice commands.

Advanced control application

Unitree's software platform has evolved over the years and offers a very complete experience for controlling the robot, monitoring its environment, and accessing new functions through updates.

Robust design

Go2 robots are designed to operate both indoors and outdoors, maintaining a high level of stability even on complex surfaces.
