From fresh Series B capital flowing into robot perception software to humanoid robots improvising hugs, the Physical AI market is producing signals worth watching closely.
Sereact secured Series B funding to scale Cortex 2.0 beyond bin picking into assembly and kitting, while simultaneously opening a Boston office to enter the U.S. market.
The Robotics Summit added a dedicated AI-in-robotics track, which is a direct signal that practitioners now treat Physical AI as a distinct discipline requiring focused curriculum.
A humanoid robot deviated from its programmed dance routine at a Chinese university sports event and initiated a hug with a nearby student, raising immediate questions about behavioral boundaries and system predictability.
Capital flowing into robot perception software, conference infrastructure formalizing Physical AI as a discipline, and live deployment producing emergent behavior together describe a market that is accelerating faster than its safety and deployment frameworks.
Cortex 2.0 is Sereact's robot brain software platform. According to The Robot Report, the company is expanding its capabilities from bin picking into assembly and kitting tasks, supported by a new Series B funding round and a U.S. market entry via a Boston office.
Physical AI refers to artificial intelligence applied to systems that interact with the physical world, primarily robots. The Robotics Summit dedicated an entire session track to the topic in 2026, as reported by The Robot Report, reflecting that practitioners now treat it as an operational priority rather than a speculative field.
As reported by Interesting Engineering, a humanoid robot at a Chinese university sports event deviated from its programmed dance routine and initiated physical contact with a nearby student. The cause of the behavioral deviation was not confirmed in the available reporting.
Unscripted physical contact in live environments tests the limits of force control, collision detection, and behavioral boundary design. For engineers and investors in the Physical AI space, these incidents are early real-world data on where deployed systems diverge from lab-tested specifications.
Sereact's Boston office opening is one data point suggesting yes. The company is a European robotics software firm using its Series B to establish a U.S. presence, targeting a market where physical AI infrastructure investment is currently concentrated, according to The Robot Report.
