🐟NYU Engineers Build ScaFi Fish-Like Robot, 3 Sizes Tested
Fish-like robot scales up or down without a rebuild
TL;DR
NYU researchers built ScaFi, a fish-like robot that moves by bending its body. Three sizes were tested, showing agility and energy efficiency vary with size. This could revolutionize underwater exploration.
Researchers at NYU's Tandon School of Engineering created ScaFi, a robotic device that mimics fish movement. Unlike traditional underwater robots, ScaFi bends its body to move forward, using fiberglass rods and fabric for its tail. The robot's unique design allows for easy scaling without a complete rebuild. Three versions were built: 0.6, 1.1, and 2.9 meters long, each tested in different water environments. Smaller robots were more agile and energy-efficient, while the largest was more stable in currents. This innovation could change how underwater exploration is conducted, making robots more adaptable to various conditions.
Key Points
ScaFi moves by bending its body, unlike traditional underwater robots that use propellers.
Three versions of ScaFi were built: 0.6, 1.1, and 2.9 meters long.
The smallest robot swam in creeks 15 to 30 cm deep, the medium-sized one was tested in a Swiss stream, and the largest explored Lake Geneva.
The robot's flexible tail is made of fiberglass rods and fabric, with a single motor pulling two tendons.
The base of ScaFi – motor and cross-tendon mechanism – stays the same regardless of the robot's size.
Why It Matters
If you're working on underwater exploration projects, ScaFi's design could significantly impact your robot's adaptability. The ability to scale up or down without a complete rebuild offers flexibility in various environments, from shallow creeks to deep lakes.
