Combustion creates Braille display for electronics

Imagine an iPad or a Kindle for the blind, with inflatable Braille that changes shape under a user's touch. A Cornell-led collaboration has made a crucial component for such a technology: A haptic array of densely packed ...

Using bundles of fibers, robots mimic nature

Octopus tentacles can move in many directions, but also form stiff joint-like structures for more precise movements. Caterpillars can travel by using inchworm movements, as well as coil up and propel themselves away from ...

Soft components for the next generation of soft robotics

Soft robots driven by pressurized fluids could explore new frontiers and interact with delicate objects in ways that traditional rigid robots can't. But building entirely soft robots remains a challenge because many of the ...

Water-driven soft actuator developed

Sea cucumbers have a bumpy and oblong shape. They are soft but stiffen up quickly when touched. They can shrink or stretch to several meters, and their original shape can be recovered even after they die and shrivel up with ...

A tactile sensing mechanism for soft robotic fingers

In recent years, numerous roboticists worldwide have been trying to develop robotic systems that can artificially replicate the human sense of touch. In addition, they have been trying to create increasingly realistic and ...

Researchers build a fast-moving jumping soft robot

Buckling, the sudden loss of structural stability, is usually the stuff of engineering nightmares. Mechanical buckling means catastrophic failure for every structural system from rockets to souffl├ęs. It's what caused the ...

SQuad: A miniature robot that can walk and climb obstacles

Researchers at Bilkent University in Turkey have recently created a small quadruped robot called SQuad, which is made of soft structural materials. This unique robot, presented in a paper published in IEEE Robotics and Automation ...

RoboBee powered by soft muscles

The sight of a RoboBee careening towards a wall or crashing into a glass box may have once triggered panic in the researchers in the Harvard Microrobotics Laboratory at the Harvard John A. Paulson School of Engineering and ...

Actuator

An actuator is a type of motor for moving or controlling a mechanism or system. It is operated by a source of energy, usually in the form of an electric current, hydraulic fluid pressure or pneumatic pressure, and converts that energy into some kind of motion. An actuator is the mechanism by which an agent acts upon an environment. The agent can be either an artificial intelligent agent or any other autonomous being (human, other animal, etc).
