A singularity-free pose realization is a key feature for any robotic system. This paper presents the development of a 3-DoF pure rolling spherical parallel manipulator (SPM) with tightly integrated ...

GitHub is where people build software. More than 150 million people use GitHub to discover, fork, and contribute to over 420 million projects.

This paper introduces a novel high-precision compliant mechanism-based 3-degree-of-freedom (3-DOF) positioning stage with a large range and planar layout. The design incorporates a cartwheel revolute ...

To address tracking errors and susceptibility to interference in the actual trajectory of the three-degree-of-freedom (3-DOF) spherical joint actuator, a model predictive tracking control scheme ...
