Going back to the Moon after half a century, and then to Mars, literally means reinventing the wheel.

After all, Mars is a long way to come back if you get a flat.

“One thing you cannot have is a puncture,” says Florent Menegaux, chief executive of the French tyre-maker Michelin.

The tough conditions on Mars have been underlined by the experience of the unmanned Curiosity rover.

Just a year after landing in 2012, its six rigid aluminium tyres were visibly ripped through with punctures and tears.

As for the Moon, the US Artemis missions aim to return astronauts there, perhaps by 2027.

Later Artemis missions plan to use a lunar rover to explore the Moon’s south pole starting with Artemis V, currently scheduled for 2030.

The Artemis astronauts will be driving much further than their Apollo forebears, who in six landings between 1969 and 1972 never ventured more than 25 miles (40km) across the Moon’s surface.

“The target is to cover 10,000 kilometres in 10 years,” says Sylvain Barthet, who runs Michelin’s lunar airless wheel programme in the central French town of Clermont Ferrand.

“We’re not talking about short, week-long durations, we’re talking about decades of utilisation,” says Dr Santo Padula, who has a PhD in materials science, and works for Nasa as an engineer at the John Glenn Research Centre in Cleveland, Ohio.

One big challenge for anyone developing technology for the Moon are the huge temperature ranges.

At the lunar poles temperatures can plunge lower than -230C, that’s not far off absolute zero, where atoms stop moving.

And that’s a problem for tyres.

“Without atom motion you have a hard time having the material be able to deform and return,” says Dr Padula.

The tyres need to be able to deform as they go over rocks and then ping back to their original shape.

“If we permanently deform a tyre, it doesn’t roll efficiently, and we have issues with power loss,” says Dr Padula.

The new wheels will also carry much bigger loads than the lightweight rovers Apollo astronauts cruised around in.

The next space missions will need to drive round “bigger science platforms and mobile habitats that get larger and larger”, he says.

And that will be an even heftier problem on Mars, where gravity is double that on the Moon.

Michelin uses high-performance plastics for its Moon tyres

Apollo’s lunar rovers used tyres made from zinc-coated piano wire in a woven mesh, with a range of around 21 miles.

Since extreme temperatures and cosmic rays break down rubber or turn it to a brittle glass, metal alloys and high-performance plastic are chief contenders for airless space tyres.

“In general, metallic or carbon fibre-based materials are used for these wheels,” says Pietro Baglion, team leader of the European Space Agency’s (ESA) Rosalind Franklin Mission, which aims to send its own rover to Mars by 2028.

One promising material is nitinol, an alloy of nickel and titanium.

“Fuse these and it makes a rubber-acting metal that can bend all these different ways, and it will always stretch back to its original shape, says Earl Patrick Cole, chief executive of The Smart Tire Company.

He calls nitinol’s flexible properties “one of the craziest things you will ever see”.

Nitinol is a potentially “revolutionary” material says Dr Padula, because the alloy also absorbs and releases energy as it changes states. It may even have solutions to heating and refrigeration, he says.

However, Mr Barthet at Michelin thinks that a material closer to a high-performance plastic will be more suitable for tyres that need to cover long distances on the Moon.

Bridgestone has meanwhile taken a bio-mimicry approach, by making a model of the footpads of camels.

Camels have soft, fatty footpads that disperse their weight on to a wider surface area, keeping their feet from sinking into loose sandy soil.

Inspired by that, Bridgestone is using a felt-like material for its tread, while the wheel comprises thin metal spokes that can flex.

The flexing divides the lunar module’s weight into a larger contact area, so it can drive without getting stuck in the fragments of rock and dust on the Moon’s surface.

Michelin and Bridgestone are each part of different consortiums that, along with California’s Venturi Astrolab, are presenting their proposed tyre tech to Nasa at the John Glenn Centre this month (May).

Nasa is expected to make a decision later this year – it might choose one proposal or adopt elements of several of them.

Meanwhile, Michelin is testing its tyres by driving a sample rover around on a volcano near Clermont, whose powdery terrain resembles the Moon’s surface.

Bridgestone is doing the same on western Japan’s Tottori Sand Dunes.

ESA is also exploring the possibility of whether Europe might make a rover on its own for other missions, says Mr Barthet.

The work might have some useful applications here on Earth.

While working on his doctorate at the University of Southern California, Dr Cole joined a Nasa entrepreneurial programme to work on commercialising some of the technology from the Mars super-elastic rover tyre.

An early product this year will be nickel-titanium bicycle tyres.

Priced around $150 (£120) each, the tyres are much more expensive than regular ones, but would be extremely durable.

He also plans to work this year on durable tyres for motorbikes, aimed at areas with rough roads.

For all this, his “dream” remains to play a part in humanity’s return to the Moon.

“So, I can tell my kids, look up there on the Moon,” he says. “Daddy’s tyres are up there.”

Intro robotics students build AI-powered robot dogs from scratch

Published

on


Equipped with a starter robot hardware kit and cutting-edge lessons in artificial intelligence, students in CS 123: A Hands-On Introduction to Building AI-Enabled Robots are mastering the full spectrum of robotics – from motor control to machine learning. Now in its third year, the course has students build and enhance an adorable quadruped robot, Pupper, programming it to walk, navigate, respond to human commands, and perform a specialized task that they showcase in their final presentations.

The course, which evolved from an independent study project led by Stanford’s robotics club, is now taught by Karen Liu, professor of computer science in the School of Engineering, in addition to Jie Tan from Google DeepMind and Stuart Bowers from Apple and Hands-On Robotics. Throughout the 10-week course, students delve into core robotics concepts, such as movement and motor control, while connecting them to advanced AI topics.

“We believe that the best way to help and inspire students to become robotics experts is to have them build a robot from scratch,” Liu said. “That’s why we use this specific quadruped design. It’s the perfect introductory platform for beginners to dive into robotics, yet powerful enough to support the development of cutting-edge AI algorithms.”

What makes the course especially approachable is its low barrier to entry – students need only basic programming skills to get started. From there, the students build up the knowledge and confidence to tackle complex robotics and AI challenges.

Robot creation goes mainstream

Pupper evolved from Doggo, built by the Stanford Student Robotics club to offer people a way to create and design a four-legged robot on a budget. When the team saw the cute quadruped’s potential to make robotics both approachable and fun, they pitched the idea to Bowers, hoping to turn their passion project into a hands-on course for future roboticists.

“We wanted students who were still early enough in their education to explore and experience what we felt like the future of AI robotics was going to be,” Bowers said.

This current version of Pupper is more powerful and refined than its predecessors. It’s also irresistibly adorable and easier than ever for students to build and interact with.

“We’ve come a long way in making the hardware better and more capable,” said Ankush Kundan Dhawan, one of the first students to take the Pupper course in the fall of 2021 before becoming its head teaching assistant. “What really stuck with me was the passion that instructors had to help students get hands-on with real robots. That kind of dedication is very powerful.”

Code come to life

Building a Pupper from a starter hardware kit blends different types of engineering, including electrical work, hardware construction, coding, and machine learning. Some students even produced custom parts for their final Pupper projects. The course pairs weekly lectures with hands-on labs. Lab titles like Wiggle Your Big Toe and Do What I Say keep things playful while building real skills.

Over the initial five weeks, students are taught the basics of robotics, including how motors work and how robots can move. In the next phase of the course, students add a layer of sophistication with AI. Using neural networks to improve how the robot walks, sees, and responds to the environment, they get a glimpse of state-of-the-art robotics in action. Many students also use AI in other ways for their final projects.

“We want them to actually train a neural network and control it,” Bowers said. “We want to see this code come to life.”

By the end of the quarter this spring, students were ready for their capstone project, called the “Dog and Pony Show,” where guests from NVIDIA and Google were present. Six teams had Pupper perform creative tasks – including navigating a maze and fighting a (pretend) fire with a water pick – surrounded by the best minds in the industry.

“At this point, students know all the essential foundations – locomotion, computer vision, language – and they can start combining them and developing state-of-the-art physical intelligence on Pupper,” Liu said.

“This course gives them an overview of all the key pieces,” said Tan. “By the end of the quarter, the Pupper that each student team builds and programs from scratch mirrors the technology used by cutting-edge research labs and industry teams today.”

All ready for the robotics boom

The instructors believe the field of AI robotics is still gaining momentum, and they’ve made sure the course stays current by integrating new lessons and technology advances nearly every quarter.

Students have responded to the course with resounding enthusiasm and the instructors expect interest in robotics – at Stanford and in general – will continue to grow. They hope to be able to expand the course, and that the community they’ve fostered through CS 123 can contribute to this engaging and important discipline.

“The hope is that many CS 123 students will be inspired to become future innovators and leaders in this exciting, ever-changing field,” said Tan.

“We strongly believe that now is the time to make the integration of AI and robotics accessible to more students,” Bowers said. “And that effort starts here at Stanford and we hope to see it grow beyond campus, too.”

Why Infuse Asset Management’s Q2 2025 Letter Signals a Shift to Artificial Intelligence and Cybersecurity Plays

Published

on


The rapid evolution of artificial intelligence (AI) and the escalating complexity of cybersecurity threats have positioned these sectors as the next frontier of investment opportunity. Infuse Asset Management’s Q2 2025 letter underscores this shift, emphasizing AI’s transformative potential and the urgent need for robust cybersecurity infrastructure to mitigate risks. Below, we dissect the macroeconomic forces, sector-specific tailwinds, and portfolio reallocation strategies investors should consider in this new paradigm.

The AI Uprising: Macro Drivers of a Paradigm Shift

The AI revolution is accelerating at a pace that dwarfs historical technological booms. Take ChatGPT, which reached 800 million weekly active users by April 2025—a milestone achieved in just two years. This breakneck adoption is straining existing cybersecurity frameworks, creating a critical gap between innovation and defense.

Meanwhile, the U.S.-China AI rivalry is fueling a global arms race. China’s industrial robot installations surged from 50,000 in 2014 to 290,000 in 2023, outpacing U.S. adoption. This competition isn’t just about economic dominance—it’s a geopolitical chess match where data sovereignty, espionage, and AI-driven cyberattacks now loom large. The concept of “Mutually Assured AI Malfunction (MAIM)” highlights how even a single vulnerability could destabilize critical systems, much like nuclear deterrence but with far less predictability.

Cybersecurity: The New Infrastructure for an AI World

As AI systems expand into physical domains—think autonomous taxis or industrial robots—so do their vulnerabilities. In San Francisco, autonomous taxi providers now command 27% market share, yet their software is a prime target for cyberattacks. The decline in AI inference costs (outpacing historical declines in electricity and memory) has made it cheaper to deploy AI, but it also lowers the barrier for malicious actors to weaponize it.


Tech giants are pouring capital into AI infrastructure—NVIDIA and Microsoft alone increased CapEx from $33 billion to $212 billion between 2014 and 2024. This influx creates a vast, interconnected attack surface. Investors should prioritize cybersecurity firms that specialize in quantum-resistant encryption, AI-driven threat detection, and real-time infrastructure protection.

The Human Element: Skills Gaps and Strategic Shifts

The demand for AI expertise is soaring, but the workforce is struggling to keep pace. U.S. AI-related IT job postings have surged 448% since 2018, while non-AI IT roles have declined by 9%. This bifurcation signals two realities:
1. Cybersecurity skills are now mission-critical for safeguarding AI systems.
2. Ethical AI development and governance are emerging as compliance priorities, particularly in regulated industries.

The data will likely show a stark divergence, reinforcing the need for investors to back training platforms and cybersecurity firms bridging this skills gap.

Portfolio Reallocation: Where to Deploy Capital

Infuse’s insights suggest three actionable strategies:

  1. Core Holdings in Cybersecurity Leaders:
    Target firms like CrowdStrike (CRWD) and Palo Alto Networks (PANW), which excel in AI-powered threat detection and endpoint security.

  2. Geopolitical Plays:
    Invest in companies addressing data sovereignty and cross-border compliance, such as Palantir (PLTR) or Cloudflare (NET), which offer hybrid cloud solutions.

  3. Emerging Sectors:
    Look to quantum computing security (e.g., Rigetti Computing (RGTI)) and AI governance platforms like DataRobot (NASDAQ: MGNI), which help enterprises audit and validate AI models.

The Bottom Line: AI’s Growth Requires a Security Foundation

The “productivity paradox” of AI—where speculative valuations outstrip tangible ROI—is real. Yet, cybersecurity is one area where returns are measurable: breaches cost companies millions, and defenses reduce risk. Investors should treat cybersecurity as the bedrock of their AI investments.

As Infuse’s letter implies, the next decade will belong to those who balance AI’s promise with ironclad security. Position portfolios accordingly.
