Abstract

As humanoid robots emerge from being mere machines to become the “Next AI Infrastructure,” the focus of hardware design is shifting. A significant amount of power is consumed during the process of precisely controlling high computational loads and dozens of joints. This makes a stable power supply crucial.

This article highlights the importance of small, high-capacity MLCCs (Multi-Layer Ceramic Capacitors) as a key component for implementing server-grade performance within a robot's compact body. It also suggests strategies for optimizing MLCCs to overcome harsh environments, such as high temperatures and vibration.

1. All-in-One MLCCs for Humanoid SoC dedicated to the Computing Module

2. High-Voltage, High-Reliability MLCCs to control Actuators in the Engine Control Unit

The dozens of actuators which enable flexible movement in humanoid robots are exposed to harsh environments, including vibration, heat generation and back-EMF. Samsung Electro-Mechanics' 100 V-class, high-voltage, high-reliability MLCCs overcome the limitations of conventional electrolytic capacitors. Our line-up ensures precise motion control even under challenging conditions.

Samsung Electro-Mechanics has developed a line-up of high-reliability MLCCs optimized for 48V drive systems, ensuring stable operation even in high-temperature environments. Moreover, the application of improved Bending Strength technology supports a robust design which mitigates physical stress, even under repetitive movements and strong vibrations experienced by robot joints.

3.High-Capacitance MLCCs for Sensors to Enable the Precise Control of Humanoids

Implementing the five senses of a humanoid robot requires precise power design within limited space. In visual sensors, where miniaturization is critical, it is important to minimize the mounting area that MLCCs occupy while stably supplying the power consumed during operation.

MLCCs mounted on balance sensors contribute to maintaining an absolute horizontal reference by minimizing capacitance variation even under vibration and voltage fluctuation while walking.

The MLCCs in the tactile sensor area act as filters, meticulously screening out electrical noise generated by the joint motors and preventing it from affecting the delicate sensor circuitry.
