Why Physical AI needs better hardware, not just better models

Written by Jennifer Kwiatkowski | Mar 17, 2026 1:00 PM

Artificial intelligence is moving fast. Large language models can write emails, summarize reports, and generate software code in seconds. But when AI leaves the digital world and enters the physical one, progress slows down dramatically.

Why?

Because interacting with the real world is much harder than processing text or images. Robots don’t just need intelligence; they need reliable ways to touch, grasp, push, and manipulate objects.

This is where physical AI enters the picture.

And it reveals an important truth: the future of robotics will depend as much on hardware design as it does on AI models.

 

What is Physical AI?

Physical AI (also called embodied AI) is the field of artificial intelligence focused on systems that can perceive and interact with the physical world.

Instead of answering questions or generating text, physical AI aims to enable robots to perform real tasks such as:

  • picking objects
  • assembling parts
  • packaging products
  • manipulating tools
  • operating machines

But while AI has made enormous progress in reasoning and perception, robots still struggle with something humans do effortlessly: manipulation.

Robots can move well. They still struggle to interact

Recent breakthroughs have made robots far better at moving through space.

Humanoid robots can walk, balance, and even perform acrobatic movements. Autonomous vehicles can navigate complex environments. Robot vacuums can map homes and avoid obstacles.

Yet when a robot tries to pick up a simple object, the difficulty increases dramatically.

This is because manipulation depends on complex physical interactions such as:

  • contact forces
  • friction
  • slip
  • compliance
  • object geometry

These variables change constantly. A robot might need to pick up:

  • a rigid metal part
  • a soft cloth
  • a slippery plastic container
  • a fragile glass object

Vision systems can detect objects and estimate position. But cameras alone cannot measure the forces and dynamics involved in contact.

That missing information creates a major bottleneck for physical AI.

The data problem in robotics

AI systems need enormous amounts of data.

Large language models were trained on billions of text examples gathered from books, websites, and documents. But physical interaction data is much harder to collect.

To train robots effectively, developers would need billions or even trillions of examples of real-world interactions.

Capturing that data is difficult because:

  • real-world experiments take time
  • hardware wears out
  • sensors can be unreliable
  • environments are unpredictable

This means every robotic interaction—every grasp, push, or insertion—must be captured accurately and repeatably.

And this is where hardware becomes critical.


Hardware can simplify the AI problem 

When people talk about robotics breakthroughs, they often focus on software.

But in practice, mechanical design can dramatically reduce the complexity of the learning problem.

Well-designed hardware can:

  • make grasps more stable
  • reduce uncertainty during manipulation
  • simplify control strategies
  • produce more consistent training data

Instead of asking AI to solve every possible interaction scenario, good hardware narrows the problem space.

For example:

  • adaptive grippers can conform to object shapes
  • force sensors provide direct measurements of contact forces
  • tactile sensors detect slip or pressure

These components give robots better feedback about the world around them.

And better feedback means better data for AI systems.

 

Mechanical intelligence matters

One way to think about this is mechanical intelligence.

Mechanical intelligence refers to hardware that solves part of the problem through design.

For example, some adaptive grippers can switch between different grasping modes automatically depending on how an object contacts the fingers. This creates more stable grasps without requiring complex control algorithms.

In other words:

Good hardware reduces the burden on software.

Instead of relying entirely on AI models, the robot benefits from built-in mechanical adaptability.

This approach aligns closely with Robotiq’s philosophy of designing plug-and-play robotic tools that simplify deployment and improve reliability.


Why end-of-arm tooling plays a critical role 

One of the most underestimated components in robotics is end-of-arm tooling (EOAT).

EOAT includes the devices attached to the robot wrist, such as:

  • grippers
  • force torque sensors
  • tactile sensors
  • specialized tools

These components are responsible for the robot’s direct interaction with the environment.

Choosing the right EOAT can:

  • improve grasp reliability
  • reduce integration complexity
  • accelerate development cycles
  • increase uptime in production

In many cases, the difference between a successful deployment and a failed one is not the robot itself—but the tooling attached to it.

Reliable mechanical design can make successful behaviors easier to achieve and easier to reproduce at scale.

The path from Physical AI to operational AI

Demonstrating a robot in a lab is one thing. Deploying it in a factory is another.

Industrial automation requires extremely high reliability.

Some researchers call this next stage operational AI—the point where AI-powered systems reach the 99.9% uptime required for real industrial environments.

Achieving this level of reliability requires more than advanced algorithms.

It requires:

  • robust hardware
  • repeatable sensing
  • durable mechanical systems
  • reliable integration

In other words, the success of physical AI will depend on the combination of hardware, software, and system design.

The future of robotics will be both mechanical and intelligent

AI will continue to improve rapidly. Models will become more capable, and training techniques will evolve.

But the robots that succeed in the real world will not rely on AI alone.

They will combine:

  • powerful AI models
  • high-quality sensors
  • intelligent mechanical design
  • reliable industrial hardware

Physical AI is not just a software revolution. It is a systems engineering challenge.

And the companies that solve it will be the ones that bring automation from research labs into everyday operations.
