Researchers have made a smart school of robotic fish that swarm and swim just like the real deal, and they offer promising insights into how developers can improve decentralized, autonomous operations for other gizmos like self-driving vehicles and robotic space explorers. Also, they’re just pretty stinking cute.

These seven 3D-printed robots, or Bluebots, can synchronize their movements to swim in a group, or Blueswarm, without any outside control, per research published in Science Robotics this month from the Harvard John A. Paulson School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering.
Equipped with two wide-angle cameras for eyes, each bot navigates their tank by tracking the LEDs lights on their peers. Based on the cues they observe, each robot reacts accordingly using an onboard Raspberry Pi computer and custom algorithm to gauge distance, direction, and heading.

Harvard SEAS develops millimeter-scale flat metalenses
28 Jan 2021
Capasso group forms 2mm achromatic metalenses that focuses RGB with mini display for AR, VR applications.
In 2018, the Capassoâs team developed achromatic, aberration-free metalenses that work across the entire visible spectrum of light. But these lenses were only tens of microns in diameter, too small for practical use in virtual and augmented reality systems.
Now, the researchers have developed a two-millimeter achromatic metalenses that can focus RGB wavelengths without aberrations and developed a miniaturized display for virtual and augmented reality applications. The research is published in Science Advances.
âThis state-of-the-art lens opens a path to a new type of virtual reality platform and overcomes the bottleneck that has slowed the progress of new optical device,â said Capasso, who is the Robert L. Wallace Professor of Applied Physics and Vinton Hayes Senior Research Fellow in Electri

Despite all the advances in consumer technology over the past decades, one component has remained frustratingly stagnant: the optical lens. Unlike electronic devices, which have gotten smaller and more efficient over the years, the design and underlying physics of today’s optical lenses haven’t changed much in about 3,000 years.
