Currently, the robot-related ETFs in the market mainly track two indices: the China Universal Robot Industry Index and the CSI Robot Index. Although both belong to the robot industry, they have different focuses in terms of coverage and style. Understanding these differences is crucial for selecting the right investment direction.
The main differences between the two indices are:
The China Universal Robot Industry Index focuses more on robot hardware, with a higher proportion of &#34;humanoid robots,&#34; while the CSI Robot Index has a broader coverage, including the upstream and downstream related industrial chains of robots.
Compilation rules: Focus vs. Diversity
In terms of compilation positioning, the China Universal Robot Industry Index primarily focuses on robot hardware, prioritizing companies involved in the manufacturing of robot bodies (such as complete machine manufacturing) and core components (such as joint manufacturing), assigning higher weights to companies in these areas, resulting in a higher proportion of &#34;humanoid robots&#34; in the index.
On the other hand, the CSI Robot Index places more emphasis on the diverse coverage of the robotindustrial chain**, with abroader selection range, including companies that are related to the robot concept and providesoftware and hardware support for robot production.
In terms of weight distribution, the weight limit for constituent stocks in the China Universal Robot Industry Index is 5%, resulting in a relatively balanced impact of major constituent stocks on the index.
In contrast, the weight of a single constituent stock in the CSI Robot Index can reach up to 10%, making the index's performance more influenced by large-cap leading constituent stocks.
The China Universal Index has a higher proportion of humanoid robots
Humanoid robots are currently the most cutting-edge field in the robot sector. As a completely new category, humanoid robots require new components and production lines. This &#34;from 0 to 1&#34; industry also harbors a vast incremental market space.
Among the constituent stocks of the China Universal Robot Industry Index, about 75% of the weight belongs to humanoid robot concept stocks, while the corresponding proportion in the CSI Robot Index is about 66%. If you are particularly optimistic about the &#34;humanoid robot&#34; future industry, the China Universal Robot Industry Index's direction is relatively clearer.
Data source: Wind, 2026/2/27, referencing the constituent stock definition standards of the Wind humanoid robot concept index, humanoid robot concept stocks were filtered from the two major robot indices, and the weight proportions of the concept stocks in the corresponding indices were statistically analyzed to obtain the humanoid robot content.
Industry distribution: Focus on robot hardware vs. both software and hardware
Robots, industrial control equipment, chassis and engine systems, and small cleaning appliances occupy a relatively high weight in both indices.
The difference is that the China Universal Robot Industry Index focuses more on the robot industry that emphasizes body manufacturing and core components, accounting for 23.7%, while the CSI only accounts for 13.9%;
The CSI Robot Index focuses more on the industrial control equipment industry used for automating industrial equipment operations, accounting for 20.5%, while the National Index only accounts for 7.3%.
Chassis and engine systems, as well as small cleaning appliances, may seem unrelated to robots, but the hardware (such as actuators) and AI technologies (such as obstacle avoidance) in these industries can be applied to robots, with both indices allocating 5%-10% weight to these two industries.
In addition, in the CSI Robot Index, horizontal general-purpose software belonging to the software sector and applicable across industries accounts for 10.20%, ranking high in weight.

Main constituent stocks: Humanoid robot hardware vs. software and industrial scenarios
Starting with the number and weight of constituent stocks, the National Robot Industry Index has only 50 constituent stocks, but the weight distribution is relatively dispersed and even, with individual stocks accounting for mostly 3%-5%, and the top ten constituent stocks accounting for about 39% of the total weight.
The CSI Robot Index has a maximum of 100 constituent stocks (currently including 66), aiming to more comprehensively reflect the entire robot industry chain. However, due to the higher weight of its top ten constituent stocks, which account for about 55%, the index's performance is more influenced by weighted stocks.
There is some overlap in the top ten constituent stocks of the two indices (the overlapping ones are highlighted in blue in the table below), with Harmonic Green, Double Ring Transmission, and other core targets in humanoid robot hardware manufacturing included, but these targets have a higher weight in the National Robot Industry Index than in the CSI Robot Index.
The distribution of industries for the top ten constituent stocks in the CSI Robot Index is significantly more dispersed and broader, with more weight tilted towards industrial robots and supporting software targets. For example, iFlytek, which provides intelligent voice technology for enterprises in various fields, has a weight of up to 10% in the index; it also includes Zhongkong Technology, Dahua Technology, and other targets in the industrial control and security fields, which are more closely related to industrial scenarios.

From the investment logic perspective, the two major indices can cater to different needs:
If you are more optimistic about the development of the humanoid robot industry in specific segments, believing that continuous breakthroughs in hardware manufacturing technology will further drive the sustained expansion of market demand, then focusing on the National Index Robot Industry Index, which has a higher &#34;content&#34; of hardware and humanoid robots, is a better choice;
If you prefer a &#34;one-click&#34; wide layout of the entire robot supporting industry chain, then the broader coverage of the CSI Robot Index may be more suitable.
Currently, among the ETF products tracking the National Index Robot Industry Index, the Robot ETF E Fund (159530, linked fund A/C: 020972/020973) is the largest product, with a scale of nearly 14 billion yuan as of March 31, 2026. The constituent stocks of this product focus on robot bodies and core components, with a high content of humanoid robots and a balanced distribution of major constituent stock weights.

When investing in the robot industry, choosing the right index is crucial. Currently, the main indices in the market are the China Universal Robot Industry Index and the CSI Robot Index. The China Universal Index focuses more on robot hardware, especially humanoid robots, with about 75% of its constituent stocks being humanoid robot concept stocks; while the CSI Index covers a broader industrial chain, with humanoid robots accounting for about 66% of its constituent stocks. The weight limit for constituent stocks in the China Universal Index is 5%, while it can reach 10% in the CSI Index. If you are optimistic about humanoid robots, the China Universal Index is more targeted
