In May 2025, Tesla Optimus robots began trial production at the Fremont factory, and Musk announced that thousands of robots would be deployed to the factory to "work" before the end of the year.

During the same period, the 1000th general-purpose embodied robot of the domestically produced Zhiyuan Robot completed debugging, and its GO-1 large model can now complete complex tasks such as hanging clothes and riding bicycles through natural language instructions, truly achieving one-time training and lifelong evolution.

Behind these phenomena is the infiltration of artificial intelligence into the physical world. These modern robots that integrate cutting-edge technologies are empowering intelligent terminals for the entire scene, gradually becoming the core force in reconstructing human production and lifestyle.

The technical foundation of the robot core system

What is a robot? The answer to this question is being redefined. Traditional industrial robots are like "mechanical puppets" that rely on pre-set programs to complete fixed actions, while modern robots already have a complete closed-loop capability of "perception decision execution".

MLCC (Multi Layer Ceramic Capacitor), as a core passive electronic component, has penetrated into six key modules of modern robot architecture and plays an irreplaceable role:

Control system: MLCC is used for decoupling the power supply of the main control chip, ensuring real-time and delay free operation of the robot's motion planning algorithm.

Drive system: The bus capacitor of the servo motor inverter needs to use high voltage MLCC, which can withstand pulse voltage above 200V and filter the motor drive.

Communication module: Implement RF front-end filtering and power supply stabilization.

Power management system: suppression of transient voltage and energy storage buffering.

Human computer interaction system: controls the coupling of audio signals and the stability of camera signals.

Biomimetic system: used to control the high-frequency response and stability of signals.

The demand for MLCC from different types of robots in diverse environments

With the iterative optimization of AI algorithm and the popularization of edge computing architecture, robots are evolving from a single functional executive to intelligent terminals with environmental awareness and autonomous decision-making capabilities.

This technological leap not only reshapes the application boundaries of robots, but also demands high frequency (5GHz+), low loss (ESR), and wide temperature range (-55 ℃~150 ℃+) performance requirements for the core passive component MLCC.

industrial robot

Industrial robots represented by welding robots and AGVs mainly work in harsh environments with high temperatures above 60 ℃ and 10G vibrations.

The MLCC usage for each industrial robot ranges from 1000 to 5000 pieces. Due to its harsh working environment, high reliability MLCCs are urgently needed to ensure stable operation of the equipment under complex working conditions.

In recent years, the global installed capacity of industrial robots has continued to rise, reaching over 500000 units for several consecutive years. From 2018 to 2023, the compound growth rate is 5%. According to the International Federation of Robotics (IFR), the installed capacity of process robots will exceed 600000 units by 2027.

The performance of the Chinese market is comparable to the global growth trend, with local suppliers accounting for 47% of the domestic market share, demonstrating strong competitiveness.

Consumer robots

From intelligent cleaning to enlightenment education, consumer robots are integrating into modern life in diverse forms.

Consumer robots such as floor cleaning robots and educational robots need to achieve a balance between miniaturization design and high-frequency data processing, which makes the usage of MLCC in a single machine reach 500-4000 pieces.

To meet the miniaturization needs of consumer robots, the proportion of MLCC packaged in 0402/0201 exceeds 70%, making high capacity and miniaturization the main development direction of MLCC in this field.

Mainly focusing on cleaning robots, compared to industrial robots, their service targets are more extensive and the market size is also larger, which is an important driving force for the growth of the robotics industry. Since 2023, the installed capacity of consumer robots has exceeded 500000 units for three consecutive years, with a compound annual growth rate of 10%, demonstrating a thriving development trend.

Special Robots

Due to the particularity of the working environment, special robots have extremely strict requirements for MLCC, with a single machine MLCC usage of up to 5000-8000 pieces, and need to withstand a wide temperature range of -55 ℃~150 ℃ and high-pressure environment.

Although the use of special robots is relatively limited, their usage requirements are extremely high. With the continuous advancement of technology and the addition of new technologies such as multimodal perception fusion and autonomous navigation, the overall performance of global special robots continues to improve, enabling them to better adapt to complex environments and task requirements.

Its global market size is also showing a trend of increasing year by year, reaching nearly $14 billion by 2024, demonstrating enormous potential in special fields.
