The robot is a highly complex system, composed of multiple key components such as power modules, actuators, sensors, motion mechanisms, environmental interaction systems, and human-computer interfaces. However, China has long faced challenges in the development of legged robots, particularly bipedal models. Bipedal robots are inherently unstable due to their shifting center of gravity, making them prone to falling and lacking sufficient support strength. Traditional control methods often fail to match the natural balance of humans, and current bipedal robots still struggle with navigating uneven terrain.
Recently, Yushu Technology made a breakthrough by releasing Laikago, China's first officially launched quadruped robot. This marks a significant step forward in the country’s efforts to catch up in the field of legged robotics. For years, Boston Dynamics has been a global leader in this area, developing iconic machines like Petman, BigDog, and Spot. Their four-legged robots have consistently demonstrated impressive performance, setting a high standard in the industry.
Now, Chinese companies are beginning to close the gap. Laikago, developed by Yushu Technology, is one of the most advanced quadruped robots in China. Weighing just 22kg, it features a self-developed motor system capable of delivering up to 18 kW of instantaneous power, with a power density nearly double that of a typical supercar. It also operates on internal battery power, providing 2–3 hours of continuous walking on a single charge.
Yushu Technology released a test video showcasing Laikago’s capabilities, including climbing slopes, traversing rocky terrain, and even replicating classic tests like the "ankle twist." The results were impressive, with Laikago performing similarly to Boston Dynamics' BigDog. While it bears a resemblance to the SpotMini, it lacks some of the advanced features, such as a visual system and an arm for grasping objects.
Laikago was developed by Wang Xingxing, who founded Yushu Technology last year. Previously known for his small electric-driven robot Xdog, Wang has now shifted focus toward commercializing quadruped robots. He envisions a future where these robots can be sold to universities, science museums, and tech enthusiasts—similar to how drones have become popular among hobbyists.
Currently, the price of Laikago ranges from $20,000 to $30,000, depending on the version. While Boston Dynamics continues to explore commercial applications, they have yet to fully bring their robots to market. In contrast, Yushu Technology aims to make legged robots more accessible through cost-effective solutions.
China is rapidly advancing in the field of legged robotics. Companies like Iron Man Technology and institutions such as Shanghai Jiaotong University and Harbin Institute of Technology are making strides in both bipedal and quadruped designs. Startups from Zhejiang University and other research labs are also contributing to this growing trend.
As the technology matures, we can expect more innovations and breakthroughs in the coming years. The race to develop intelligent, mobile, and versatile legged robots is just beginning, and China is proving to be a strong contender in this exciting field.
