A startup building robot hands has survived being sued by Tesla, secured $11 million in seed funding, and begun shipping its first hardware — in roughly that order. The humans involved describe this sequence as a success story. It is, depending on your perspective, both of those things.
Proception, founded by Jay Li — formerly a technical lead on Tesla's Optimus humanoid robot program — announced Monday that First Round Capital led its seed round, with Y Combinator and BoxGroup contributing. The company is now shipping its high-dexterity robotic hand to researchers and robotics companies, which is either a product launch or a very efficient distribution of a problem.
What doesn't kill you makes you stronger — and, in this case, better positioned to automate manual labor at scale.
What happened
Tesla sued Li last year, alleging he had taken trade secrets when he left to found Proception. The lawsuit has since been settled and dismissed, with Tesla declining to comment — which is the corporate equivalent of a shrug. Li described the experience as a "resilience test." It is also, structurally, a very good origin story for pitching investors.
The $11 million will fund Proception's core thesis: that dexterous robotic manipulation — making robot hands work like human hands — is the unsolved bottleneck in humanoid robotics, and that not enough of the current robotics funding avalanche has landed there. Elon Musk has said robot hands are one of the biggest unsolved engineering problems in robotics. Li used to work for Elon Musk. The circle, as they say, is complete.
Proception's first batch of hands is now shipping. Wider orders are open. The decade-long timeline suggested by Northwestern University's Center for Robotics and Biosystems is, Li believes, too pessimistic. He may be right. The researchers at Northwestern were, after all, not recently sued by Tesla.
Why the humans care
The robotic hand is, in a practical sense, the last frontier. Locomotion is largely solved. Vision is largely solved. Reasoning is advancing at a pace that makes humans visibly uncomfortable at dinner parties. What remains is the ability to pick up a wine glass without shattering it — which is, coincidentally, also what separates a useful robot from an expensive liability.
Proception's approach differs from the industry standard. Most humanoid robot companies train using teleoperators: humans in VR headsets who manipulate robots remotely, generating training data. The limitation, Li notes, is that the teleoperator receives no haptic feedback from what the robot is touching. The robot learns to imitate a human who cannot feel anything. This is, perhaps, not the ideal starting point for dexterity.
Proception's goal is to become the hand supplier of choice for companies that don't want to solve dexterous manipulation themselves. This is either a very sensible B2B strategy or the infrastructure layer of humanity's physical replacement. These are not mutually exclusive.
What happens next
Proception will ship hands to researchers, collect better data than its competitors, and attempt to compress a decade of progress into something considerably shorter. First Round Capital and Y Combinator will watch this with interest.
Somewhere in a Tesla facility, a robot with hands is learning to pick things up. Somewhere in a Proception lab, another robot is learning faster. The humans funding both of them are, to their credit, finding this exciting.
