Sunday's slate leans philosophical and practical at once, from a fresh look at why Asimov's tidy Three Laws don't map onto real AI safety, to the messy supply-chain reality of rare earths that make robots possible. We've also got a Chinook refueling from an uncrewed barge, an FDA-cleared exoskeleton, and a modular take on robot intelligence.

In today’s roundup

• Asimov’s laws are not enough to keep robotics and AI safe — The Robot Report
  A useful reality check that fictional safeguards, however elegant, don't translate into engineering practice for governing today's robotics and AI.
• 5 companies working to expand America’s rare earth processing capacity — Interesting Engineering
  Robotics runs on rare earths, so this look at US processing capacity matters for anyone worried about where the raw materials come from.
• First for US Army: MH-47G Chinook helicopter refuels from autonomous barge at sea — Interesting Engineering
  An Army first that hints at how autonomous surface vessels could reshape logistics and refueling far from traditional bases.
• FDA-cleared exoskeleton puts spinal-cord patients back on their feet — New Atlas Robotics
  FDA clearance moves a self-balancing exoskeleton from lab promise to real independence for people with spinal-cord injuries.
• General Robotics is betting on modular intelligence, not one robot brain — The Robot Report
  A bet that composing specialized skills, rather than chasing one all-knowing model, is the better path to robots that adapt across tasks and form factors.
