Danu Robotics is raising $5M to sell a claw-based recycling sorter

In short: Danu Robotics, a six-year-old Edinburgh startup, is bringing H.E.R.O. — an AI vision and gripper system for material-recovery lines — to market while raising a $5 million late-seed round (TechCrunch corrected its Oct 9 story to say the round is in process). It reports $500,000 in signed contracts, letters of interest from two large customers, and more than 200 prospects in a Europe–North America sorting market it pegs at $20 billion.

What H.E.R.O. does

Most robotic waste pickers use suction cups. Danu's machine uses a pincer claw that can grip heavier, awkward items, plus cameras and onboard AI that score items by "recycling worth" before the end effector picks them. Founder Amy Ma estimates about $485,000 in extra annual revenue per working line versus roughly $160,000 upfront and $24,000 yearly maintenance.

Why it matters

Recycling margins live or die on purity and labor. A cheaper, claw-based sorter that keeps improving via software is a direct attack on that bottleneck — and a path, Ma says, to smaller at-source units for malls, hospitals and airports once the robot shrinks.
