Non‐linear calibration optimisation based on the Levenberg–Marquardt algorithm [PDF]
IET Image Processing, 2020 An outstanding calibration algorithm is the most important factor that affects the precision of attitude measurement. This study proposes a non‐linear optimisation algorithm to refine the solutions of the initial guess obtained using the Zhang's technique, the Bouget's technique, or the Hartley's algorithm.

Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots
Advanced Robotics Research, EarlyView.A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.
