VecBound node_bounds_
same bounds for each discretized node
virtual ~BaseMotionConstraint()=default
Constraints evaluated at discretized times along a trajectory.
std::shared_ptr< NodeSpline > Ptr
Definition: node_spline.h:52
virtual void UpdateJacobianAtInstance(double t, int k, std::string, Jacobian &) const override
Sets Jacobian rows at a specific time t, corresponding to node k.
Eigen::VectorXd VectorXd
Holds pointers to fully constructed splines, that are linked to the optimization variables.
Definition: spline_holder.h:46
BaseMotionConstraint(const Parameters &params, const SplineHolder &spline_holder)
Links the base variables and sets hardcoded bounds on the state.
void UpdateConstraintAtInstance(double t, int k, VectorXd &g) const override
Sets the constraint value a specific time t, corresponding to node k.
Holds the parameters to tune the optimization problem.
Definition: parameters.h:45
void UpdateBoundsAtInstance(double t, int k, VecBound &) const override
Sets upper/lower bound a specific time t, corresponding to node k.
Keeps the 6D base motion in a specified range.
