Saturday's slate leans toward the strategic and the sobering: intellectual property as competitive moat, and two separate signals that militaries are organizing seriously around autonomous and robotic warfare. For balance, there's a muscle-powered swimmer from MIT, practical advice on mobile robots and warehouse upgrades, and a conference deal worth a look if you're between jobs.

In today’s roundup

• The physical AI race will be won in the patent office — The Robot Report
  A reminder that in physical AI, defensible IP may matter as much as working hardware—provided startups are selective about what they actually protect.
• US Task Force 401 taps drone defenses that autonomously classify threats — Interesting Engineering
  Digital Force Technologies' US contract signals demand for counter-drone systems that fuse sensors and classify threats autonomously rather than leaning on human operators.
• 5 signs it’s time to upgrade your material handling system — Automated Warehouse
  A practical checklist for warehouse operators weighing whether their material handling setup is quietly capping throughput and ripe for automation.
• China readies military for drone and robotic warfare with new specialized colleges — Interesting Engineering
  The PLA's new training institutions suggest China is treating drone and robotic warfare as a discipline worth building dedicated colleges around.
• Inside Omron’s next-generation LD mobile robots — The Robot Report
  Omron's take underscores a maturing truth in AMRs: software, safety, and fleet management now carry as much weight as the chassis itself.
• MIT robot swims through water via living muscle cells — New Atlas Robotics
  A single layer of living muscle cells steering a tiny robot toward light is a striking, if slow, glimpse at biohybrid actuation.
• Computational tools for society’s most complex challenges — MIT News Robotics
  Cathy Wu's work applying reinforcement learning to transportation shows robot-learning methods reaching beyond robots into messy, real-world systems.
• Affected by layoffs? Don’t miss this $75 deal for your TechCrunch Disrupt 2026 Expo+ Pass — TechCrunch Robotics
  A discounted Disrupt Expo+ Pass aimed at those hit by layoffs—a modest but genuine networking lifeline for the first hundred who qualify.
