[Science World] The Reason for Not Giving Up on Researching 'Humanoid Robots'

A robot that walks on two legs like a human is called a "humanoid robot." In the early 2000s, humanoid robots were considered a fascinating novelty. However, skepticism about these robots began to grow. The main reason was the uncertainty about their practical use. The bipedal walking structure is inherently less stable compared to wheeled designs, which led to such criticism. It also became difficult to secure proper research funding. As a result, humanoid robot research seemed to enter a dark age.

The persistent challenges faced by scientists and engineers never ceased. Thanks to their efforts, related technologies have continuously advanced. For example, running, which is easy for any human, is difficult for robots. In the past, only a few companies like Japan’s Honda and Toyota possessed such technology. Among robots developed for research purposes at universities, Korea’s KAIST was the first to create a robot called "Hubo" capable of running. This running technology has become somewhat widespread. Recently, researchers at UCLA in the United States introduced "Artemis," a robot capable of running, which attracted attention. Currently, the most advanced humanoid robot is "Atlas," developed by Boston Dynamics in the U.S. It walks and runs on two legs, rolls on the ground, and even performs backflips. Watching these robots, it seems that the discussion about their practical utility has moved beyond the technical stage.

Why do scientists and engineers not give up on humanoid robot research? Some researchers offer a humanities-based explanation: "As the most natural helper to humans, their form should also resemble humans." Whether this is the correct answer is uncertain. What we do know is that, considering the current technological trends, there is a realistic expectation that within a few decades, humanoid robots could be deployed in special situations such as disaster relief and rescue operations, replacing humans.

Necessity breeds technology. But sometimes, technology also creates new needs. Could this be the case with humanoid robots?
