I wonder how to generate double s-curve velocity profile for multiple DOF trajectory. Since there are constraints on initial and final velocities which can be non-zero it is necessary to synchronize each DOF in time. Therefore firstly I would like to compute trajectory for DOF with the largest displacement and then trying to fit other DOFs in the computed execution time for the former. However I was not able to find anything about generating s-curve profile with given time. Having tried to solve it by myself I came up towith a conviction that it is an optimization problem. I tried several approaches but they all seemed to have extremely non-convex cost function and hardly could they satisfy constraints on final velocity. Having spent much time I wondered if there is an easy way to synchronize them?
