The roundup also features an ETH Zurich lab video that asks whether such designs are safe for home use and viable alternatives to humans.\n\nNYU Tandon researchers demonstrate an undulatory robot, WorMa, that pumps water between head and tail to boost traction on a 19.5‑degree incline and climb steps up to 15 cm high.  Shifting water forward reduces the robot’s cost of transport by at least 33 percent compared with other configurations.  Other highlights include the Kubi 2.0 telepresence AI robot launching on Kickstarter, DEEP Robotics’ waterproof underwater quadruped with a SO(3) attitude controller, UBTECH’s humanoid factory scaling production from 1,000 to 10,000 units in under nine months, and MIT’s robotic optics lab that assembles and aligns optical components using QR‑coded housings.  The video set also covers lunar‑terrain rovers, a bee‑colony augmentation project, and several upcoming robotics events.","keyPoints":["Two birotors latch together to act as a quadrotor, demonstrating modular aerial design.","NYU Tandon’s WorMa shifts internal water to climb 19.5° slopes and 15 cm steps, cutting transport cost by ≥33%.","MIT’s robotic optics lab automates component assembly with QR‑coded parts, speeding material‑testing experiments."],"whyItMatters":"The videos highlight emerging techniques—modular flight, fluid‑based locomotion, and automated lab robotics—that could broaden AI‑driven physical systems in industry and research.","category":{"slug":"robotics","name":"Robotics & Physical AI","url":"https://digestai.news/category/robotics"},"entities":{"companies":["ETH Zurich Robotic Systems Lab","NYU Tandon School of Engineering","Kubi 2.0","DEEP Robotics","UBTECH","MIT"],"models":[],"people":["Kostas","Erol Şahin"]},"firstPublishedAt":"2026-09-18T16:01:05Z","updatedAt":"2026-09-18T16:01:05Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"IEEE Spectrum Robotics","title":"Video Friday: Two Birotors Make a Quadrotor","url":"https://spectrum.ieee.org/video-friday-quadrotor-from-birotor","publishedAt":"2026-09-18T16:01:05Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Two birotors combine to form a quadrotor in robotics video\", 18 September 2026, https://digestai.news/story/two-birotors-combine-to-form-a-quadrotor-in-robotics-video","publisher":"Digest AI","title":"Two birotors combine to form a quadrotor in robotics video","datePublished":"2026-09-18T16:01:05Z","url":"https://digestai.news/story/two-birotors-combine-to-form-a-quadrotor-in-robotics-video"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
