NUS team achieves multi-segment bending in soft robotic arm using continuous artificial muscle

A team from the National University of Singapore's College of Design and Engineering published research in Science Advances using wire-bonded junctions (WBJ) inspired by octopus neuromuscular junctions, enabling a single shape-memory alloy spring artificial muscle to heat and contract in selected segments, achieving multi-segment controllable bending along a continuous arm without needing an independent actuator at each position.
