Claire chatted to Michelle Lu from Vsim Technology about using simulation and artificial intelligence to teach robots new skills. Michelle Lu is co-founder and CEO of Vsim Technology . She was previously a Director of Simulation Technology at NVIDIA, where she and her co-founder created the world's first end-to-end GPU-accelerated reinforcement learning (RL) framework, Isaac Gym, which set the template for how modern GPU-accelerated simulation-based RL is performed in robotics. In 2022, Michelle and her co-founder left NVIDIA to create Vsim, driven to solve the limitations that plague simulation-based robotics AI: efficiency, scalability and the sim-to-real gap. Robot Talk is a weekly podcast that explores the exciting world of robotics, artificial intelligence and autonomous machines.

"Robotics and automation" is a pairing heard often around these parts. It puts the "RA" in IEEE RAS, after all. The familiar combination shows up in conference titles, funding calls, and program descriptions. But what is actually meant by the two words? Is robotics a subdomain of automation?

Propeller-powered underwater vehicles have long helped scientists explore and monitor aquatic environments. But they're limited by their own mechanics: spinning blades can snag on vegetation, stir up sediment, and startle the wildlife they're often sent to study, making them poorly suited to shallow creeks, dense weeds, or close encounters with fish. That's one reason roboticists have spent years building machines that swim like fish instead, bending their bodies rather than spinning a propeller. The catch is that most fish-inspired robots are built for one size and one job, so scaling them up or down usually means starting from scratch. A team of engineers at EPFL and New York University (NYU) says it has found a way to solve that problem.

Lights blink on as I enter the Rover Operations Center at NASA's Jet Propulsion Laboratory in Pasadena, California, at 7:30 a.m. I'm the first to arrive, even though I already feel late. Sometime during the night on Earth, the Curiosity rover finished its day exploring on Mars and beamed its latest collection of images and measurements to a Mars orbiter zooming by overhead. The orbiter relayed the data to Earth, where it now waits on servers here and at partner institutions around the globe. Once our rover operations shift kicks off at 8:15 a.m., a few dozen engineers and scientists will have just three hours to check the health of the rover, analyze the new science data and agree on the next set of rover activities.

Imagine a robot designed to install solar panels with much greater speed and precision than a human. The robot is made from expensive materials and powered by a heavy battery that must be recharged every few hours. If the costs of building and operating the robot outweigh the benefits of the clean energy it helps produce, can it really be considered sustainable? In a 2025 article published in, Aude Billard, head of the Learning Algorithms and Systems Lab in EPFL's School of Engineering and Academic director of the Robotics Center, gives precisely this example to illustrate the tension between robotic performance and sustainability. Roboticists, she argues, can no longer ignore the fact that robots use energy-intensive power systems and electronic components made from finite resources.

The 2026 IEEE International Conference on Robotics & Automation (ICRA) was held in Vienna from the 1 - 5 June. The event brought together researchers and industry professionals with expertise spanning many different aspects of robotics. IEEE have made the keynote and plenary talk recordings available to watch . You can also catch the panel discussions and keynote tutorials. Panel 4 - Publish or Perish: Surviving the Paper Deluge - Is AI the solution?

In early August, The Information published an article that claimed U.S.-based founders, investors and startups, are travelling to an electronics market in Shenzhen to buy servomotors, sensors, controllers and gimbals. The report also claimed that Unitree and Zhiyuan robots are being bought intact, then stripped down into parts and carried back to the USA in suitcases. By late August, in a separate development, reports emerged that a US Department of Energy lab is investigating whether Chinese LiDAR sensors pose a security risk, if widely used on vehicles in the United States. According to TechCrunch, the research is being funded by one or more companies in the electric and autonomous vehicle industries. Don't cancel any Shenzhen travel plans just yet, but engineers at Princeton have unveiled a motorless, origami-inspired robot that can roll, crawl, and change shape through a combination of magnetic control and multistable geometry.

From 25-27 August, UK RAS STEPS members came together at the University of York's Institute for Safe Autonomy for a three-day Micromaze Robot Hackathon. Working in teams, participants were challenged to design, build and program autonomous robots capable of navigating a series of increasingly complex mazes. Each team used a custom Raspberry Pi Pico W robotics platform, designed a laser-cut chassis, integrated motors and sensors, and developed its control software in MicroPython. Participants had access to ultrasonic, infrared and time-of-flight sensors, alongside laser-cutting and 3D-printing facilities. The final challenge considered maze performance, collision avoidance, robot design, code quality, wireless control and any innovative features developed by the teams.

Could robots help tackle loneliness? BBC's Ann Droid raises questions about the future of care New BBC sitcom Ann Droid imagines a near future in which robots provide care and companionship to older people at home. The series centres on Sue, a recent widow played by Sue Johnston, her hapless son Michael and Linda, an assistive care robot played by Diane Morgan. Linda is designed to provide daily support and companionship, with predictably comic results. As researchers in social care, ageing and human-centred robotics, we obviously watched Ann Droid with a keen eye.

NASA is planning to send three small rovers to the Moon with a single instruction: Work out among yourselves how to explore a patch of ground. The Cooperative Autonomous Distributed Robotic Exploration mission, or CADRE, will land on the side of the Moon facing Earth as part of NASA's IM-3 launch, planned for late 2026. These rovers will spend roughly two weeks mapping the terrain as a self-guided team. No joystick will control them, and no human will approve each turn. The rovers will elect a leader among themselves, assign their own tasks and redraw their plans as a group when one of them runs low on charge.
