On November 18, 2025, scientists from Carnegie Mellon University in the United States developed a new 3D printing process and successfully manufactured micro Delta robots named microDeltas. These robots, with heights of only 1.4 millimeters and 0.7 millimeters, are the smallest and fastest of their kind to date, achieving sub-micron precision and operating at frequencies exceeding 1 kilohertz. They are expected to play a significant role in fields such as micro-manipulation, micro-assembly, minimally invasive surgery, and wearable haptic devices. Related research has been published in the latest issue of Science Robotics magazine.
