Robotic factories that build robots (opens the original)
Read excerpt
Tensr is building robotic factories that build robots. Their 12,000-square-foot factory is already making humanoids, end effectors, and even robots for the International Space Station. Every order becomes training data for the factory to manufacture the next one better. YC Y Combinator
Robot-Use Agents: Why General-Purpose Models May Win in Robotics (opens the original)
Read excerpt
One of the biggest surprises in AI over the last few years has been how well coding agents generalize beyond software. In a recent essay, MIT professor Philip Isola argued that we may be entering the era of robot-use agents: general-purpose models that can control different robots, write policies, and learn new physical tasks with little or no robot-specific training. In this episode of Decoded, we're joined by the founders of Waddle Labs and RoboCurve, two of the startups whose work helped driv
Rocket cargo delivery anywhere on Earth in minutes (opens the original)
Read excerpt
Hop Aero is building rockets that can deliver cargo anywhere on Earth in minutes. They’re starting with military logistics and other time-sensitive payloads, including temperature-controlled materials with short shelf lives, where getting something there much faster can materially change the outcome. They’ve already built and successfully hot-fired a new rocket engine, and signed $1.37B in commercial LOIs. YC Y Combinator
Autonomous construction on Earth and beyond (opens the original)
Read excerpt
A lot of construction work is still done by hand simply because the machines to automate it don’t exist. That’s become a bottleneck for building things like solar farms, data centers, and other critical infrastructure. Cosmic Robotics is building those machines. Their robots have already installed 11,000 solar panels, and they just signed a major contract with the largest construction company in the country. They’re building the construction robots we’ll need on Earth today, and eventually on th
Drone swarm defense (opens the original)
Read excerpt
Attack drones are reshaping modern warfare, but many countries still lack an effective way to defend their airspace. Earendil Robotics is building autonomous interceptors, along with the software and training needed to stand up that capability from scratch. Their systems can take off, transit, and intercept targets on their own, reducing months of pilot training to a few clicks. The goal is air defense that’s affordable enough to deploy in large numbers and simple enough to operate at scale.
