[ROB26-07] The Map of Selling Robots: From Cleaning Robots to Physical AI and Defense Robots

When we look at the robot market, we should not only look at laboratory news or futuristic demonstrations. Robots are already being sold in open markets, entering homes, restaurants, hospitals, farms, education, pet care, and even defense.

The ROB26-07 series looks at robots not only as future technology, but as a real product market, service market, parts market, and supply-chain opportunity.

01｜Robots Are Already Being Sold

On platforms such as Amazon, Rakuten, Shopee, Coupang, and Naver, we can already see robot vacuums, pool-cleaning robots, serving robots, pet-care robots, educational robots, desktop companion robots, and AI-powered companion robots.

The key question is not which robot looks futuristic. The real question is which robots people are already paying for. Once robots start selling, new demand follows: parts, apps, data, maintenance, subscriptions, certification, and supply-chain services.

02｜Robots Are Expanding Across Homes, Stores, Healthcare, and Farms

At home, robot vacuums have become the entry point for robot adoption. In restaurants and stores, serving robots and guide robots are moving toward RaaS, or Robot as a Service.

Healthcare and care robots are linked to aging populations, caregiver shortages, and remote monitoring. Agricultural and field robots are expanding because of labor shortages, repetitive work, and hazardous environments.

This means the robot market cannot be explained by finished products alone. Robots become real markets when location, repeated tasks, data, and service models are combined.

03｜Educational Robots and Pet Robots Are Entering the Home

Grand View Research estimates that the educational robot market will grow from about USD 1.38 billion in 2024 to about USD 5.84 billion by 2030.

Educational robots are not just toys. They can combine learning content, voice AI, parental control apps, subscriptions, and interactive learning services.

The pet-care market also matters. In Korea, the total number of households was about 23 million in the 2024 Population and Housing Census. If we apply the Ministry of Agriculture, Food and Rural Affairs’ 2025 pet ownership rate of 29.2 percent, the market can be viewed as roughly 6.7 million households living with companion animals.

Pet robots are not just monitoring devices. They are becoming home-service devices that help owners check, interact with, and connect with pets when they are away.

04｜Robots Are Becoming Physical AI

Robots are no longer just machines. They are moving data devices. They see with cameras, listen with sensors, calculate location, and continuously generate data.

When AI is added, robots become Physical AI: systems that can perceive, decide, and act in the physical world.

Grand View Research estimates that the military robots market will grow from about USD 19.68 billion in 2024 to about USD 32.5 billion by 2030.

The U.S. Department of Defense’s Replicator initiative aims to deploy low-cost autonomous unmanned systems across multiple domains. Korea is also moving toward manned-unmanned teaming through Army TIGER and related defense robot concepts, including robot scouts, robot carriers, and robotic security systems.

05｜The United States Is Treating Robot Supply Chains as a National Security Issue

On March 26, 2026, the American Security Robotics Act of 2026, S.4235, was introduced in the U.S. Senate. The bill aims to restrict federal agencies from procuring or operating certain Covered Unmanned Ground Vehicle Systems.

An unmanned ground vehicle system is not just a vehicle. If drones are unmanned robots in the air, unmanned ground vehicle systems can be understood as robots that move on the ground for surveillance, patrol, transport, security, and operational missions.

Another important signal comes from the U.S. Department of Commerce and BIS. On September 2, 2025, BIS initiated a Section 232 national security investigation into imports of robotics and industrial machinery. The scope includes not only finished robots, but also parts and components.

If these trends connect, the robot market may shift from simple technology competition to trusted supply-chain competition.

06｜The Opportunity for Korean Companies Is Inside the Supply Chain

The opportunity is not limited to finished robots. Reducers, motors, sensors, actuators, batteries, controllers, communication modules, security modules, data security, and maintenance services can all become part of the opportunity.

However, this does not mean automatic benefit. Companies will need to prove origin, parts composition, data transmission paths, cybersecurity, local assembly potential, and actual supply capability.

Robots are moving beyond consumer products. They are becoming a strategic industry that can reshape national security and global supply chains.
