Tiny Swimming Robots Could Be Modeled After Spiral-shaped Bacteria

December 21, 2009May 23, 2015 Mike Henry No Comments

Spiroplasma is a type of spiral-shaped bacteria that travels in a corkscrew type motion. It accomplishes this motion by sending kinks down the spiral of its cell structure. And, it turns out this method of propulsion is very efficient. Essentially, it is using its entire body as a propulsion unit. This may prove to be…

A robot pangolin designed to plant trees is the winner of the 2023 Natural Robotics Contest, which rewards robot designs inspired by nature. As the winning entry, the pangolin—dubbed "Plantolin"—has been brought to life by engineers at the University of Surrey in the United Kingdom.
Balancing cost and reliability in autonomous machine design
October 3, 2024
With millions of self-driving cars projected to be on the road in 2025 and autonomous drones generating billions in annual sales, safety and reliability are important considerations for consumers, manufacturers, and regulators. But solutions for protecting autonomous machine hardware and software from malfunctions, attacks, and other failures also increase costs. Those costs arise from performance […]

This Biohybrid Robot Is Made of Human Cells and Controlled by a Machine ‘Mind’
September 30, 2024 by Shelly Fan
In a tiny laboratory pond, a robotic stingray flaps its fins and swims around. Roughly the width of a dime, the bot dashes distances multiple times its body size. It easily navigates around corners and swims far longer than previous flapping microbots of a similar design. Its secret? The robot is a biohybrid blend of […]
Waymo Robotaxis Are Giving 100,000 Rides a Week. It’ll Soon Be More.
September 5, 2024 by Jason Dorrier
After years of overly aggressive forecasts about self-driving cars, here’s a statistic that snuck up on us: People are now hailing 100,000 automated rides a week—a number that’s double the 50,000 weekly rides provided a few months ago. These rides are courtesy of Waymo, the self-driving car project incubated by Google and spun out as […]
Robots Are Coming to the Kitchen—What That Could Mean for Society and Culture
September 3, 2024 by Patrick Lin
Automating food is unlike automating anything else. Food is fundamental to life—nourishing body and soul—so how it’s accessed, prepared, and consumed can change societies fundamentally. Automated kitchens aren’t sci-fi visions from The Jetsons or Star Trek. The technology is real and global. Right now, robots are used to flip burgers, fry chicken, create pizzas, make […]
Icon’s Enormous 3D Printer Extrudes a New 100-Home Neighborhood
August 11, 2024 by Jason Dorrier
In November 2022, Icon and Lennar started 3D printing homes for a new neighborhood in Texas. Now, according to a report by Reuters, the 100-home project is nearly complete. While foundations, roofing, and finishes were built and installed traditionally, the walls of each house were constructed by Icon’s Vulcan 3D printer. Vulcan uses a long, […]
A Massively Strong Beetle Just Inspired a Lightweight Flying Robot
August 1, 2024 by Shelly Fan
One of the largest and strongest beetles in the world hardly seems the best inspiration for a delicate flying microbot. But using slow-motion cameras to capture the critters in flight, an international team designed a flying micromachine that can similarly expand and retract its wings. The robot—resembling a rocket before takeoff and a flying insect […]
