Why Intelligence Is Not Enough To Get Robots Out Of The Cage
The industrial automation landscape is shifting towards collaborative human-robot environments, with the market projected to reach $17.2 billion.
Key takeaways
- The most recent headlines show a rapid expansion of humanoid robots across industry, consumer markets, and healthcare.
- Chinese automaker BYD, now the world’s top EV seller, is leveraging its fleet of about 200 factory‑floor robots to develop new humanoids for production lines, dealerships and, eventually, homes, with a goal of placing three units in every household.
- XPeng unveiled its next‑generation IRON robot, a 5‑foot‑8‑inch machine that combines 82 degrees of freedom with an electronic‑skin‑covered, bionic spine and a 3‑D curved facial display for lifelike expressions.
- Unitree continues to dominate volume shipments, reporting roughly 10,000 humanoids sold to date, including 5,500 in 2025, as it prepares for a Shanghai IPO.
- In the consumer space, San Francisco startup Weave Robotics began delivering its wheeled Isaac 1 home robot, priced at $7,999, to perform chores such as laundry folding and bed‑making.
The industrial automation landscape is shifting towards collaborative human-robot environments, with the market projected to reach $17.2 billion. Despite this growth, 89% of industrial robots remain caged, largely due to inadequate 2D safety systems that fail in dynamic 3D spaces. Sonair Robotics CEO Knut Sandven notes that current laser sensors are insufficient for safe human-robot interaction. Sonair has pioneered the first independently safety-certified 3D ultrasonic sensor, enabling robots to reliably detect humans throughout an entire working volume, not just a flat plane. This innovation allows for the removal of physical cages and fosters trust, underscoring that safety must be deterministic and separate from AI's probabilistic models. The landscape of industrial automation is shifting from restricted machine zones to collaborative human-robot environments. Fourteen years ago, Rodney Brooks’ Rethink Robotics introduced Baxter to the manufacturing environment. Baxter was designed to work outside of its cage. Rethink closed in 2018, but Baxter’s cage-free DNA laid a foundation for today’s cobot environment. “This 3D certification takes certified safety for a mobile machine from 2D to 3D for the first time,” he said in an email interview. “Until now, a robot could only be certified to detect people in a flat plane. It could only see a single slice of the world. Certifying 3D ultrasonic sensing gives the industry a proven, deterministic way to detect a human anywhere in a volume, not just across a line on the floor.”
Sandven says that lets robots work closer to people, with protection throughout the entire workspace. “This is a safety layer the whole robotics industry can build on, whatever robot or AI is built on top of it,” he added.
