Researchers build robot system for automated soft actuator production
20-layer soft capacitors built by robots 14% faster with 56% less human input
Researchers from the University of Connecticut and collaborators have demonstrated a fully automated robotic manufacturing line for dielectric elastomer actuators (DEAs)—soft, flexible devices that function as both actuators and sensors. Published on arXiv (2608.00369), the system automates two critical processes: dielectric layer formation via spin coating and carbon nanotube (CNT) electrode application through precision stamping.
In a production run, the robotic system consistently fabricated 20-layer DEAs with a mean dielectric thickness of 55.37 ± 2.04 micrometers and 19 alternating CNT electrodes—each device operating as a soft capacitor. Compared to manual methods, the automated process cut total fabrication time by 14.2% and reduced human involvement in 56.1% of steps, significantly improving repeatability and throughput for mass production of soft robotic components.
