Laikago - ROBOTS: Your Guide to the World of Robotics

Laikago is a four-legged robot designed as a research platform. It can walk on uneven terrain, climb hills, and remain stable even when kicked.
Laikago's name was inspired by Laika, the Soviet space dog, to represent exploration of the unknown.
Unitree Robotics, based in Hangzhou, China, was founded by Xingxing Wang, who began developing quadruped robots during his graduate studies. His early projects, including XDog and Laikago, explored a low-cost approach to high-performance legged locomotion using brushless motors and custom control systems — a design direction that has since become widely adopted across the field. Since its founding, Unitree has emphasized in-house development of core components, including actuators, sensors, and control systems, and was among the first companies to bring high-performance quadruped robots to the commercial market at scale.
Today, Unitree Robotics offers a broad portfolio of legged and humanoid systems, spanning consumer-oriented quadrupeds, industrial platforms, and emerging bipedal robots such as the Unitree Go2 quadruped robot, the G1 humanoid, and the H1 humanoid. The company continues to prioritize vertically integrated design, developing key hardware such as motors, controllers, and lidar alongside its own motion control, perception, and AI-driven software. This tight integration supports robots with advanced mobility, real-time sensing, and autonomous decision-making in complex environments, from inspection and mapping to research and public-facing deployments.
With a track record of commercializing high-performance quadrupeds at scale and maintaining global sales leadership, Unitree has established a prominent position in the legged robotics sector, helping push these systems from niche research platforms toward broader practical use.
