What Are Humanoid Robots, and How Does the Robotics Industry Work?

By Adam Patti, Chief Executive Officer, VistaShares | November 2026

Humanoid robots are machines built in a roughly human form, with a torso, arms and often legs, designed to work in spaces and with tools made for people. They combine motors and actuators, sensors, batteries, onboard computing and AI models that turn what the robot perceives into movement. They are an emerging segment of a robotics industry that today is dominated by industrial robots working in factories.

What is the difference between industrial robots and humanoid robots?

Industrial robots are typically fixed in place and perform repetitive tasks, such as welding, painting, assembly and material handling, inside defined work cells. Most are programmed for specific motions and operate behind guards or in areas separated from people.

Collaborative robots are smaller industrial robots designed to work alongside people, with sensors and force limits that allow them to share space safely.

Mobile robots move through warehouses, hospitals and other facilities, carrying goods or performing inspections.

Humanoid robots aim to combine mobility with manipulation in a general-purpose form. Because factories, warehouses and homes are built for human bodies, a robot with a similar shape could, in principle, use the same stairs, doorways, workstations and tools without redesigning the environment.

How big is the robotics industry today?

Industrial robots are the established core of the industry. According to the International Federation of Robotics, about 542,000 industrial robots were installed worldwide in 2024, more than double the number a decade earlier, and annual installations have exceeded 500,000 units for four consecutive years.¹ The global operational stock of industrial robots reached about 4.66 million units in 2024.²

China accounted for 54% of global installations in 2024, with about 295,000 units, and its operational stock exceeded 2 million robots. Chinese manufacturers supplied 57% of the robots installed in China that year.¹ The United States installed about 34,200 industrial robots in 2024, and China’s operational stock is about five times that of the United States.³ The IFR expected installations to rise to about 575,000 units in 2025 and to exceed 700,000 units by 2028.¹ Forecasts may not be realized.

Humanoid robots are a small part of this total today. Many are in pilot programs or early commercial deployments, mainly in manufacturing and logistics.

How does a humanoid robot work?

A humanoid robot brings together several systems that must work closely together.

Actuators. Actuators are the motors and gear systems that move each joint. A humanoid may have dozens of them. Precision reducers, such as harmonic and planetary gearboxes, convert motor speed into the torque needed to lift and grip. Actuators are among the most significant cost components.

Hands. Dexterous hands with many joints and tactile sensors are one of the hardest engineering problems, because handling varied objects requires fine control of force and position.

Sensors. Cameras, depth sensors, force and torque sensors, and inertial measurement units allow the robot to see its surroundings, sense contact and maintain balance.

Power. Battery packs supply energy for movement and computing. Battery capacity limits how long a robot can work before recharging or exchanging batteries.

Onboard computing. Processors on the robot handle perception, motion control and safety functions in real time.

AI models. The software that controls humanoids is changing quickly. Newer approaches use large AI models trained on video, simulation and demonstration data to map what a robot sees and is asked to do into actions. These are sometimes called vision-language-action models. Simulation lets developers train robots on many virtual scenarios before testing them in the physical world.

Why has interest in humanoid robots increased?

Advances in AI. Models that can interpret instructions and visual scenes have made general-purpose robots more practical than rule-based programming allowed.

Labor availability. Aging populations and shortages in manufacturing, logistics and other physical work have increased interest in automation that can adapt to existing workplaces.

Component costs. Higher production of motors, sensors, batteries and chips for other industries has lowered the cost of key parts.

Government priorities. Several governments, including China’s, have identified humanoid robotics as a strategic industry and set targets for its development.⁴

What challenges do humanoid robots face?

Reliability. Robots must perform tasks consistently over long shifts and in varied conditions. Moving from demonstrations to dependable work is a significant step.

Dexterity. Many tasks that people find simple, such as handling soft or irregular objects, remain difficult for robots.

Safety. Robots that move freely among people must meet safety standards for collisions, falls and failures. Standards for mobile and humanoid robots are still developing.

Cost and payback. Buyers compare the cost of a robot, including maintenance and integration, with the productivity it delivers. That comparison determines how widely robots are adopted.

Energy. Battery life limits continuous operation and adds weight.

How does robotics connect to other industries?

Robotics draws on the same components and technologies as other advanced sectors. AI models and the chips that run them link robotics to the AI supply chain, and training those models relies on computing capacity in data centers. Autonomous systems overlap with developments in the defense supply chain, where unmanned vehicles and drones are expanding. Batteries and motors connect robotics to electrification more broadly.

How can investors think about the robotics industry?

The robotics value chain includes component suppliers, such as makers of actuators, reducers, sensors, batteries and chips; robot manufacturers; software and AI developers; and system integrators that install robots and connect them to customers’ operations. Many humanoid developers are private, while public exposure often comes through established industrial automation companies, component suppliers and technology companies with robotics programs.

Each part of the chain carries different risks. Component suppliers may benefit from robot production regardless of which manufacturer succeeds, but they also serve other cyclical industries. Robot makers face heavy development costs and uncertain timelines for commercial adoption.

What are the risks of investing in robotics?

Adoption timing. Commercial deployment of humanoid robots may take longer than expected, and early products may not meet buyers’ requirements.

Cyclicality. Industrial robot demand tends to follow manufacturing investment, particularly in the automotive and electronics industries, which can be cyclical.

Competition. Many companies are developing humanoid robots, and pricing pressure may be significant.

Geopolitical and trade risk. Supply chains for components and manufacturing are concentrated in a few countries.

Valuation. Market expectations for an early-stage technology can move ahead of commercial results. Investments involve risk, including possible loss of principal.

Frequently asked questions

Why build robots in a human shape?

Most workplaces, tools and infrastructure are designed for the human body. A robot with a similar form can, in principle, climb stairs, open doors and use existing equipment without redesigning the environment. The trade-off is engineering complexity, since balance, walking and dexterous hands are harder to build than specialized machines.

How are humanoid robots trained?

Developers combine several methods: recording people demonstrating tasks, training in physics simulations where robots can practice many scenarios quickly, and learning from video and other data. AI models trained this way map camera images and instructions to movements. Robots are then tested and refined on real tasks before deployment.

What is an actuator?

An actuator is the component that produces movement at a robot’s joint, usually an electric motor paired with a gearbox and sensors. It converts electrical energy into controlled motion and force. Humanoid robots use many actuators, and their performance, weight and cost strongly influence what the robot can do and what it costs.

Where are humanoid robots being used today?

Most deployments are pilots or early programs in manufacturing plants and logistics facilities, where robots move materials, handle parts or perform repetitive tasks. Use in homes and other unstructured settings is at an earlier stage, because those environments are more varied and safety requirements are stricter.

How do industrial robot statistics relate to humanoids?

Statistics from the International Federation of Robotics mainly track industrial robots, such as robotic arms in factories. Humanoid robots are a separate, emerging category that is small by comparison. Industrial robot data shows the scale of factory automation and the supply chains for components that humanoid robots also use.
