The Design and Testing of a Cross-Scale Compliant Rotary Actuator with Minimum Actuation Redundancy and Sub-Microradian Resolution

Solving the common paradoxical problem between sub-micro-arc level resolution and a wide range of rotation angles in rotary actuators, this paper designs a single-drive compliant rotary mechanism (CRM) and develops a cross-scale compliant rotary actuator (CCRA). Specially, the proposed CRM employs a...
