Detailed Description

Options passed to the Path Inverse Kinematics solver.

Use method chaining for in-line construction and modification, e.g: pathIK(..., PathIKOptions().setBlendingRadius(0.1), ...);

◆ setNullspaceOverrideFunction()

PathIKOptions & cartesian_planning::PathIKOptions::setNullspaceOverrideFunction ( const NullspaceOverrideFunction &  function)
inline

Set a nullspace override function.

This allows users to inject custom nullspace costs into the path IK solver. The function is called after the built-in nullspace tasks (joint limit avoidance, orientation tracking) have been computed, and can modify or replace the nullspace component. It takes the current nullspace component and the current joint values as input, and should return the modified nullspace component.

Example usage:

options.setNullspaceOverrideFunction(
[](const Eigen::VectorXd& nullspace, const Eigen::VectorXd& joints) {
// Add a custom cost to keep joint 3 near zero.
Eigen::VectorXd modified = nullspace;
modified[3] += -0.01 * joints[3];
return modified;
});
