Robots, humanoids, robotaxis, drones
Reducers, bearings, servos, sensors and edge compute decide where AI leaves the data center and does paid physical work.
What stops robots and autonomy from scaling to serial volume?
Physical AI index vs S&P 500
Equal-weight, rebased to 100 · 1Y9 bottlenecks in Physical AI
Sorted by tightness score. Click through for supply chain, dimension scores, names and falsifier.
Precision Reducers
Every robot joint needs a strain-wave or RV reducer. Two Japanese firms dominate; Chinese suppliers are scaling fast.
Drones & Defence Autonomy
Autonomous systems are now central to defence budgets. Motors, batteries and sensors with non-China supply chains are scarce.
Vision, LiDAR & Tactile Sensing
Robots and vehicles see through CMOS sensors and LiDAR. Dexterous manipulation still lacks good, cheap tactile sensing.
Servo Motors & Drives
Motors and drives are the muscle of automation, and rely on rare-earth magnets that come mostly from China.
Autonomy & Robotaxi
Driverless fleets are scaling city by city. Sensors, compute, mapping and permits gate the rollout.
Bearings, Screws & Linear Motion
Humanoids use planetary roller screws and precision bearings in quantity. Roller-screw capacity is small and specialised.
Robot Brains (Edge Compute)
Running vision-language-action models on the robot needs power-efficient edge accelerators — a smaller cousin of the datacentre race.
Factory Automation & Integration
Reshoring and labour scarcity push automation spend. Integrators and controls vendors are the existing, profitable expression of physical AI.
Robot Platforms & Humanoids
Pilots and funding are real; paid serial deployments are early. Public exposure is mostly incumbents and Chinese platforms.
