Bioptim, a python framework for musculoskeletal optimal control in biomechanics
(Institute of Electrical and Electronics Engineers, 2022-06-28)Musculoskeletal simulations are useful in biomechanics to investigate the causes of movement disorders, to estimate non-measurable physiological quantities or to study the optimality of human movement. We introduce Bioptim, an easy-to-use Python ... -
Optimal 3D arm strategies for maximizing twist rotation during somersault of a rigid-body model
(Springer, 2020-10-07)Looking for new arm strategies for better twisting performances during a backward somersault is of interest for the acrobatic sports community while being a complex mechanical problem due to the nonlinearity of the dynamics involved. As the pursued ... -
Optimal estimation of complex aerial movements using dynamic optimization
(Routledge, 2022-06-01)When estimating full-body motion from experimental data, inverse kinematics followed by inverse dynamics does not guarantee dynamical consistency of the resulting motion, especially in movements where the trajectory depends heavily on the initial state, ... -
Optimal forward twisting pike somersault without self-collision
(Routledge & International Society of Biomechanics in Sports, 2022-03-23)In acrobatic sports, twisting fast before piking allows athletes to enlarge their scoring potential. Since planning the arm and hip movements to twist fast is unintuitive, optimal control appears as a powerful and risk-free tool. To our knowledge, ... -
Optimality equivalence and computational advantages of free-floating base dynamics compared to full-body dynamics
(Elsevier, 2022-12-19)Several transcription methods exist for predictive simulations of free-floating base motions like athlete performing twisting somersaults. Following a brief overview of the literature, we proposed two original direct multiple shooting optimal control ...
