Video Friday: Digit Redecorates — 14 Real-World Clips, From a Couch Drag to a Grape Harvest Above 50 °C

IEEE Spectrum's Video Friday collected fourteen robotics clips this week. Nearly all of them show robots working in the real world rather than in a render. Agility's Digit drags a couch across a living room; SteadyTray's ReST-RL hierarchical reinforcement learning keeps unsecured payloads level on a Unitree G1, generalizing zero-shot sim-to-real across objects and external force disturbances; Figure argues that a robot in every home is a safety-and-cost problem rather than a data-and-compute one; CMU's APEX replaces choreographed motion with adaptive full-body maneuvers. NC State builds teardrop-shaped liquid-crystal elastomer soft robots that leap for as long as infrared light is on, with no battery, controller, or onboard sensing, and the University of Tokyo fits the musculoskeletal humanoid Musashi-W with a three-layer joint-covering skin carrying 44 pressure- and stretch-sensitive elements. DEEP Robotics' Lynx M20S hauls grape baskets in Turpan, where summer ground temperatures exceed 50 degrees Celsius, while ROBOTIS' first OH! GYM! student cohort goes from simulated motions to a physical AI Sapiens K1 in one month. The edition also carries the September-to-November event calendar: Humanoids Summit Seoul, IROS 2026, and CoRL 2026.
