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 ...

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 soufflés. It's what caused the ...

Team prints seaweed-based, biodegradable actuators

Traditionally, soft robots have been made using synthetic polymers, rubbers, and plastics. Such materials provide soft robots with long operational lives and stable structures, but may pose risks to the environment if lost ...

Mimicking biological movements with soft robots

Designing a soft robot to move organically—to bend like a finger or twist like a wrist—has always been a process of trial and error. Now, researchers from the Harvard John A. Paulson School of Engineering and Applied ...

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 ...
