Harvard scientists 3D print swarm of ‘Bluebot’ synchronized soft robotic fish

Researchers from Harvard University have 3D printed a school of soft robotic fish that are capable of swimming in complex patterns without the aid of Wi-Fi or GPS.

Inspired by the distinctive reef-dwelling surgeonfish, the team’s ‘Bluebots’ feature four fins for precision navigation, and a system of LEDs and cameras that enable them to swarm without colliding. The self-sufficiency of the tiny bots could make them ideal for ecological monitoring applications, in areas that wouldn’t otherwise be accessible to humans.

“Just by observing how far or close they are in a picture, they know how far or close the robot must be in the real world. That’s the trick we play here,” the study’s lead author Florian Berlinger told Wired.

Latest Starlink Satellites Equipped with Laser Communications, Musk Confirms

The latest Starlink satellites launched on Jan. 24 are equipped with laser links, and all Starlink satellites launched next year will be equipped with laser inter-satellite links, Elon Musk, SpaceX chief engineer confirmed on Twitter.

“All sats launched next year will have laser links. Only our polar sats have lasers this year and are v [version] 0.9,” Musk tweeted on Monday.

A Twitter user noticed a difference in a photo of the stack of 10 Starlink satellites deployed on Sunday’s Transporter-1 rideshare mission, and asked Musk if an object that looked like a black pipe was lasers, which he confirmed.
