Dynamics of pendulum-based systems under human arm rotational movements

•Pendulum-based system parameters are identified by fitting a single degree of freedom model on the experimental data.•Arm’s rotation effect on the pendulum-based system behavior is considered by defining several rotation matrices.•The system shows several types of bifurcations under amplitude or frequency sweep, including pitchfork bifurcation and cascades of period doublings.•The bi-stable response consists of both rotary and oscillatory responses.
