EurekAlert  June 16, 2021 Researchers at the University of Colorado exploited the principles of spiders’ joints to drive articulated robots without any bulky components and connectors. The Electrohydraulic Soft-actuated joints (SES) joints comprised of both rigid and softer elements can be used in many different configurations. The joints use electrostatic forces to locally pressurize a hydraulic fluid, and cause flexion of a segmented structure. SES joints with rotation angles up to 70° blocked torques up to 70 mN m, and specific torques up to 21 N m kg−1 have been demonstrated. SES joints demonstrated high speed operation, with measured roll-off […]
