Frequently Asked Questions

Frequently Asked Questions (FAQs)

Does Crocoddyl depend on Pinocchio?

No, it doesn't; Crocoddyl main core classes are agnostic to any physics engine. However, we have conveniently defined different action and cost models that strictly depend on Pinocchio.

---

Why do we need to define data classes for action and cost models?

Crocoddyl has been designed to be efficient. Creating data structures allow us to define static methods and to avoid waste of time with dynamic memory allocation.

---

Is the Crocoddyl API compatible with the use of polynomials for the control trajectory?

Yes, it is. Polynomials can be implemented by modifying the integration classes, however, we have only implemented piecewise constant at the moment.

---

Is the Crocoddyl API compatible with soft contact models?

Yes, it is. You can model soft contact dynamics through a dedicated differential action model. So far, we haven't implemented yet.
