5 Ws Robotics, Automation & Control
A team of researchers at Cornell Engineering has developed a soft robot that can detect when and where it was damaged — and then heal itself on the spot.
Researchers produced a soft, mechanical metamaterial that can “think” about how forces are applied to it and respond via programmed reactions.
Researchers designed a new type of soft robotic gripper that uses a collection of thin tentacles to entangle and ensnare objects.
The aim was to use renewable resources derived from plants and other sources to prepare high-performance carbon fiber and thermosetting matrix resins with high strength and high thermal resistance.
The researchers used water as the solvent and developed an LCST-type thermoresponsive polymer by adding alkaline earth metal ions — which are divalent cations — to polymers and aqueous solutions.
By embedding enzymes inside the polymer string, the enzymes were operational even in a dry state.
