The 360 long line has the most potential. 360: At present, 360 is the most famous service robot brand in China, and its YY robot has played a very good role in service scenes such as hotels, airports and shopping malls, and established a strong brand awareness and user base. With the development of 5G technology, 360 has great potential in realizing robot radar and location service. Tom Cat: Tom Cat focuses on providing friendly robots, and product design pays more attention to human-computer interaction and emotional experience. With the growth of the elderly population in China, the market demand for interactive entertainment and health management robots is increasing, and Tom Cat should have a good development prospect in this respect. But because the pace of innovation may be a bit slow, it is difficult to gain market share quickly. Wan Wei, Kunlun: Wan Wei, Kunlun mainly provides robot development services and kits, so it is difficult to release independent robot products. However, the accumulation of professional technology provides a solid foundation for them to enter the robot manufacturing industry or ride robots in the future. Its robot technology has also been adopted by brands such as 360 and Tom Cat, with high influence. Generally speaking, Kunlun Wan Wei has great potential for future development, but its position in the industry may be difficult to reverse 360 and Tom Cat. Generally speaking, the overall potential of 360 is very strong, and Tom Cat and Kunlun Wan Wei also have good development prospects in specific fields, but they are not as good as 360 on the whole, so the long-term 360 is still good.
