RobTalk

Physical AI is everywhere right now. Most definitions sound right, but almost none of them help you decide what to do on your own shop floor. So this RobTalk episode takes the opposite approach. Instead of describing what Physical AI could be, Clemens Marschner from RobCo shares what it is not, and what that means for your first project. Every week, Clemens reviews real customer requests with RobCo’s sales engineers and product managers. Clear patterns have emerged from those conversations. This episode shares them, together with two hands-on experiments: the tong test and an ice bath that takes away the sense of touch.

Made for CIOs, COOs, production managers and anyone with an AI budget who is asking: where do we start?

What Physical AI is not: Not a large language model with a robot attached Not a humanoid that can do everything a human can Not a replacement for every human job Not the answer to every automation problem Not something you unpack and switch on And not a reason to wait

You’ll gain insights into:

The tong test: a simple first check for any task you want to automate What an ice bath reveals about touch, sensors and robot grippers Why mechanics, not AI, is now the bottleneck in many applications Why a robot runs on half a gaming GPU while a chatbot query runs on a data center When classic automation wins and when AI-based robotics makes sense

Safety today: industrial standards, cobots and humanoids Why a small first project sets you up for long-term success

Is 2026 the year world models make Physical AI real? Vision-Language-Action models have become the standard approach to robot learning over the last few years. In this episode, Felix Frank from our Robot Intelligence team explains why the next shift is already underway: world models that predict what happens next before a robot decides what to do. We cover how the field moved from small, task-specific models to large pretrained architectures, why memory and context work differently in robotics than in language models, and why robots still need to run at high frequency with very limited context per decision. We also break down the two competing approaches to building a world model: one that generates full video in pixel space, and one that predicts directly in a compressed latent space, closer to the JEPA approach. Finally, we talk about where world models actually help today: generating synthetic training data, predicting the action needed to reach a desired future state, and simulating multiple possible outcomes before choosing one to execute.

You'll gain insights into:

• Why Vision-Language-Action models became the default approach in robotics
• How robots handle memory and context differently than language models
• Why control frequency, not context length, is the real constraint in robotics
• Two different ways to build a world model, and the trade-offs between them
• Why touch and force sensing matter as much as vision for some tasks
• Why mechanical and electrical engineering remain the next big bottleneck

Is legged locomotion actually a solved problem? In this episode of RobTalk, Felix Frank from our Robot Intelligence team explains how legged robots learn to walk, and why going from an impressive stage demo to a reliable real-world deployment is still one of the hardest open problems in robotics.

You'll gain insights into:

• Why footstep planning used to mean months of hand-engineered optimization
• How GPU-parallelized simulation and domain randomization changed the entire approach
• What retargeting means, and why human motion data now trains robot policies
• The difference between imitation learning and adversarial motion priors
• Why legged robots face real safety and power challenges that fixed robots don't
• What is still unsolved: combining blind whole-body control with real terrain understanding

Do dancing robots we see prove that autonomous robotics has been solved?

Autonomous Robotics are becoming more impressive every year. They can dance, run marathons and perform movements that seemed impossible just a few years ago.

But does that mean they’re ready for real industrial applications?

This episode takes an honest look at where the technology actually stands, what those demos can and cannot do, and what the next real milestone looks like.

You’ll gain insights into:

• Viral robot videos being scripted,, and what that means
• Robots having gone from not being able to stand 10 years ago to running marathons today
• Movement vs. understanding: the gap nobody talks about
• What would actually impress an engineer instead of seeing a backflip
• How close we are to robots working in factories for eight hours straight

Industry 5.0 is not a tech upgrade. It is a different question entirely.

Where Industry 4.0 asked what machines can do, Industry 5.0 asks where we want to be as a society. That shift changes everything: Who writes the standards, what factories are optimized for, and what the real role of AI and robotics actually is.

You'll gain insights into:

• what Industry 5.0 really is, why it comes from a completely different place than 4.0, and what that means for how technology is built and used
• the three pillars that define it: human centricity, sustainability and resilience
• how RobCo is already putting these principles into practice

How do robots go from human instruction to real movement?

Telling a robot to “pick up a box” sounds simple. But behind that command is a complex chain of decisions: understanding language, interpreting the environment, choosing the right action and turning it into physical movement.

In this episode, Clemens (Principal Engineer) and Robert (Robotics Engineer & Researcher) explain how RobCo approaches this challenge with ALFIE - combining classical robotics, AI models, sensors, safety systems and real-world industrial requirements.

You'll gain insights into:

• the three-layer hierarchy (System 2 / System 1 / System 0) that turns language into motor currents
• why physical grounding is the hardest unsolved problem in robotics today
• how 100-200 demonstrations are enough to fine-tune Alfie on a new use case
• why methods that brought man to the moon are now central to physical AI

How do you actually teach an AI-powered robot?

For decades, robots in industry have followed one principle: You program every single step. Every movement. Every position. Every exception.

And if something changes, you start again.

That approach is reaching its limits.

As environments become less structured and processes more dynamic, the question shifts: How do you move from programming robots… to teaching them?

You'll gain insights into:

• how to physically guide a robot arm
• what a VR headset, a gripper replica, and a helmet camera have in common
• why data quality matters more than data quantity
• how close we really are to just talking to a robot and getting an answer

90% of robot prototypes never make it to real factories.

They work in a closed lab. They look impressive on video. And then reality hits.

In this episode, we break down what actually separates a convincing prototype from a system that runs reliably in production. And why that gap is much harder to close than most people think.

You'll gain insights into:

• what makes a prototype fail in real deployment
• why 99% reliability is harder than it sounds
• how the digital twin works inside a neural net
• where humanoid robots really stand today

Dancing robots. Kung-fu moves. Humanoid acrobatics all over the feed. But does that mean Physical AI has actually arrived?

In this episode, Clemens, Principal Engineer at RobCo, shares what Physical AI really means for industrial automation and where the technology stands today.

You'll gain insights into:

• why Large Language Models are just the starting point and what comes after
• how robots are being taught today compared to five years ago
• how RobCo approaches Physical AI in real manufacturing environments
• where the technology stands today and what accuracy rates actually matter in practice
