Re: Contact force oscillations/parameter tuning
Hi Pasha,
Sorry to reopen this old topic. Could you give me some suggestions on how you finally solved the problem of oscillation and spikes occured in vertical ground reaction force ?
Best Wishes,
Matthew

Re: Some questions about how to create and use some customed plugins in Moco
Hi Nick, Thanks very much for your quick reply! Related to the above two questions, I still need your help: 1. If I don't customize a new objective function. In other words, I am only using the objective function provided by Moco, such as the most common MocoControlGoal , to minimize the control squ...

Re: Unexpected interruption of optimization iterations
What is the magnitude of the objective value? Dear Nick, Thanks very much for your quick reply! The objective function value is around 0.7, which is within [0.1,10]. My convergence tolerance is set to 1e-3. The final iterations are as follows: iteration.JPG I look forward to getting more guidance f...
