Eka's Robot Picks Things Up by Feel. It Hasn't Run a Factory Year Yet.
Eka Robotics raised $150 million at a $1.45 billion valuation for a robot arm that grasps by force and touch rather than mainly by sight. Experts who've seen it are impressed. But it's in private pilots, not general release, and its gripper is rated for a quarter of the cycles industrial arms are expected to last.

Robots are still surprisingly bad at picking things up. Eka Robotics thinks it knows why, and investors just valued it at $1.45 billion to find out.
The Idea: Grab by Feel, Not Sight
Most robot “foundation models” learn mainly from cameras and language. Eka’s co-founder Pulkit Agrawal (MIT) puts it simply:
“Vision tells you roughly where the object is… but the actual grabbing, the actual searching is happening through forces.”
So Eka built a vision-force-action model: a gripper packed with force sensors, trained on how objects push back. That’s why it can pick up a raspberry without crushing it.
It was trained mostly in a physics simulator, not from people demonstrating tasks. Eka says it can produce thousands of hours of robot practice in minutes, and the robot can learn to do better than any demonstration it was shown.
What It Can Do (by Eka’s Numbers)
- ~1,500 picks per hour, objects up to 1 kg, versus ~600 for a person
- Over 95% success rate
- Retries when it misses, without retraining for new objects
Experts who’ve seen it are unusually excited. Professor Kris Hauser (Illinois) called it a “wow factor.” A roboticist at a frontier lab compared it to when robots first learned to walk reliably.
The Correction
Some coverage says Eka’s model is “now commercially available.” The primary reporting doesn’t say that. TechCrunch reports Eka is in secretive pilots with industrial customers, focused on two jobs: pick-and-place and wire handling. The company “still needs to prove itself in the field.”
This is a funded, impressive prototype heading into real factories. It isn’t a product you can order yet.
The Number That Matters for Buyers
Eka’s gripper costs under $1,000 and is rated for 5 million cycles. Standard industrial arms are expected to hit 20 million.
That’s a quarter of the lifespan. Hauser’s point is the right one:
“What’s going to be a big challenge is when they work with integrators on real assembly lines, and it needs to run without breaking for an entire year.”
Demos run for minutes. Factories run for years.
Why It Matters Anyway
The interesting split is between thinking and touching. General AI models can now plan robot tasks: “plates go in the cupboard.” They’re slow and clumsy at the physical part. Eka is building the physical part, so a general model could decide and Eka’s handles the dish without breaking it.
That’s a different bet from most of the field, which works top-down from intelligence. Eka works bottom-up from contact. Critics like Rodney Brooks have long argued robots will fail without a real sense of touch. Eka’s results suggest they had a point.
Where I’d Push Back
The performance numbers are Eka’s. No independent field data yet.
Two tasks so far. Pick-and-place and wire handling. Much of factory work is more complex.
Durability is unproven at industrial scale.
What to Do With This
- If you run warehouse or light assembly operations, watch the pilots. Pick-and-place of mixed, fragile items is the use case.
- Ask about duty cycles and service before believing any robot ROI model.
- Treat “physical AI” claims like software claims: demos first, a year of uptime second.
The Fog
The headline is “physical AI model hits $1.45B.” The useful version is: a genuinely new approach to grip, impressive in demos, in private pilots, with a lifespan question still open. All three are true. Only the first one made the headline.
