Tomorrow’s Humans Are Rising Fast — But Can We Test Them Fast Enough?

Market research projects that the global humanoid robot market will grow from approximately $2.1 billion in 2020 to nearly $7.9 billion in 2025, with long-term estimates reaching $38 billion by 2035. Key growth drivers include labor shortages, rising automation demand in logistics and manufacturing, and aging populations in developed economies.

Humanoid Robot Industry Chain Overview

The humanoid robot industry is composed of several interconnected segments. Below is a simplified illustration of the value chain:

Core Architecture of Humanoid Robots

While humanoid robots vary in form and function, most share a common structural framework:

- Actuation System: Includes motors, gears, and joint assemblies for motion.
- Power System: High-density lithium-ion battery packs.
- Perception System: Cameras, LiDAR, IMUs, and force sensors.
- Control & Computation: Embedded CPUs, GPUs, real-time OS.
- Communication Interface: Wired and wireless protocols (Ethernet, CAN, WiFi, 5G).

This integrated system enables bipedal locomotion, object manipulation, facial recognition, voice interaction, and adaptive decision-making.

Testing Challenges in Humanoid Robot Development

As humanoid robots grow more sophisticated, so do the challenges in validating their performance and reliability. Developers face complex testing demands across both the component and system levels.

Key Testing Areas Related to Power Electronics:

a. Motor Drivers and Joint Actuators
