Key Components Shaping the Humanoid Robot Market

Part of understanding the market is examining the components and technology used to develop a humanoid robot. These will impact the quality, cost, supply chain, and aftermarket services.

Those areas must continue to mature for the humanoid market to meet expectations. There’s a potential shift from hydraulic to electric-powered, costs are too high, the supply chain is evolving, and aftermarket services aren’t fully developed or understood. 

Plus, everyone knows that underlying technology and software are evolving fast. I’ve done my best to put together an initial list of suppliers. Many are missing, so I’ll update as I research and analyze the market. And I’ll use the information to feed into my deeper analysis and reports.

What Is a Humanoid Robot

But before we jump into the technology, we must define what we mean by a humanoid robot. So, let's keep it simple.

A humanoid robot resembles a human, can operate in the human environment, perform multiple tasks, receive instruction, and continue to learn.

Now that we know what a humanoid robot is, we can talk about its underlying technology.
