Open
Robot software/OS interoperability layer
Lightberry builds voice/LLM 'brains' on top of Unitree hardware while Philon and Forge Robotics build their own full-stack robots; as more teams bolt AI brains onto varied hardware (Unitree, custom arms, humanoids), a shared middleware/OS to abstract hardware differences becomes necessary to avoid each startup reinventing low-level drivers.
Next investigation
Check back around August 2027 for new YC batches, to see whether independent evidence for "Robot software/OS interoperability layer" has appeared.
Open
Defense-grade simulation-to-real transfer validation
Null Labs explicitly sells simulation infrastructure to defense companies to train and validate autonomous systems, implying a gap between simulated training and real-world battlefield deployment that will require dedicated sim-to-real validation/certification services as defense robotics scales.
Next investigation
Check back around August 2027 for new YC batches, to see whether independent evidence for "Defense-grade simulation-to-real transfer validation" has appeared.
Cortex AI and Null Labs are both building large-scale real-world and simulation datasets to train embodied AI, but with multiple competing data providers (Cortex AI, Piggy Robotics generating chore data, Null Labs simulation) there's no neutral way to compare model performance across these disparate datasets, creating demand for standardized evaluation infrastructure.
Next investigation
Check back around May 2027 for new YC batches, to see whether independent evidence for "Third-party robot data/eval benchmarking infrastructure" has appeared.
Open
Safety/liability certification for consumer and low-cost humanoid robots
Piggy Robotics is pushing humanoid robots to 'iPhone prices' for home chores, and Tornyol is deploying autonomous drones with lethal mosquito-killing mechanisms in consumer/home settings; mass deployment of physically-acting autonomous devices in homes will trigger demand for safety certification and liability frameworks not yet built for this price/scale tier.
Next investigation
Check back around November 2027 for new YC batches, to see whether independent evidence for "Safety/liability certification for consumer and low-cost humanoid robots" has appeared.
Robots for high skilled labor powering AI infrastructure. Shepherd Robotics builds general purpose robots for skilled physical work across AI infrastructure and advanced manufacturing. Our robots are powered by robot foundation models and use modular, flexible hardware designed to adapt to different environments and tasks. We train our systems on a combination of real world and simulation data so they can learn complex manipulation skills and generalize across workflows. We also provide integration into customers’ existing workflows, starting with data center construction and operations, electrical manufacturing and testing, and electronics manufacturing, where traditional automation struggles with variability, dexterity, and changing environments.
Quick-turn, purpose-built motors & actuators for all. We design and manufacture high-mix drone motors and robotic actuators in LA. DJI, Apple, and Ford don't settle for OTS components. Likewise, the teams that win the Western robotics market will build seamless machines from tightly integrated software and hardware. Pendulum Robotics designs motors and actuators around your robot's unique form factor and mission - then we rapidly bring them to life with proprietary software and tooling geared for high-mix machining and assembly. Our first factory in LA can create thousands of motors per month up to 200mm OD. We're doing for motion components what 3D printing has done for structural components. Hardware teams that can build and iterate at the speed of software will create elegant, reliable, ROI-positive robots and win massive markets.
The generalist robot deployment company.. Deploy's core belief is that robots should be useful. Getting a generalist robot to do real work is fundamentally the same problem across industries. We build everything between the model and the task to bring generalist robots to the businesses that actually need them.
Robots that learn on the job. We deploy robots that learn new tasks from a single human demonstration in the factory. We're starting in contract manufacturing, where lines change every week and both traditional automation and today's VLAs fall over. Our founding team has 20+ years of experience in robotics. Navid was part of the core team that productized Spot at Boston Dynamics and led manipulation projects there. Before that, he was at Rethink Robotics. Mojtaba led whole-body control and manipulation efforts at Amazon Robotics and was a Research Assistant Professor at Northwestern University.
Autonomous construction on Earth and beyond. Our mission is to build a city on Mars. Cosmic-1, the first equipment in our fleet, is an autonomous robot capable of heavy-lift manipulation. Its been deployed on some of the largest solar farms in the US, more than doubling labor productivity across tens of thousands of panel installs. We're scaling in solar, expanding in data centers, and building lunar construction robotics under contract with NASA.
Evaluating robots in the real world.. Robocurve builds open-source tools and independent benchmarks to measure how well robots can do real-world jobs. Instead of relying on unverified demo videos from frontier labs, we score their models on reproducible benchmarks that anyone can trust. Today there are no well-run, standardized robotics benchmarks. Labs evaluate in-house, and no independent group has stepped in to run continuous benchmarking as a service. The result is that no one actually knows how good anyone else is, or where the real frontier sits. Good benchmarks require operating and maintaining physical hardware and real-world setups. Simulation only goes so far, since models that look strong in sim can show large performance gaps once deployed in the real world. Building real-world benchmarks means coordinating job-domain experts, evals engineering, and hands-on robotics all at o
Inside Robotics
Manufacturing and Robotics
A primary internal company segment within Robotics, derived deterministically from the shared yc industry “Manufacturing and Robotics”. This is a classification of current window members, not a causal layer or a separate time trend.
Other / unclassified
Measured-window members of Robotics that could not be assigned to a narrower shared YC tag or industry without forcing a classification.
Outside corroboration — does anyone else see this?
Similarly named categories — not necessarily the same thing
These share a word with “Robotics” but are tracked as separate categories. The real overlap below is the actual share of Robotics’s companies also found in that category — not a guess.
