Kinematic analysis of a double-closed-loop four-bar chain-based leg for a multimodal quadruped-pentarotor robot
This research paper presents the kinematic modeling and singularity analysis of a three-degree-of-freedom, double four-bar closed-loop quadruped leg mechanism designed for a multimodal quadruped-pentarotor robot. The study examines the leg in both joint and task spaces to develop its Jacobian matrix, which is crucial for designing gaits for terrestrial mode and mid-air aerial reconfiguration. Various gaits were devised through MATLAB simulations, and their practical implementation was demonstrated on a single-leg test rig.
The paper provides kinematic modeling and singularity analysis for a specific quadruped leg mechanism, supported by MATLAB simulations and single-leg test rig demonstrations.
