DART Model Loading (dart::io)

Load this skill when working with robot model files or parsers.

Quick Start

#include <dart/io/Read.hpp>

// Format auto-detection
auto world = dart::io::readWorld("dart://sample/skel/chain.skel");
auto skel = dart::io::readSkeleton("dart://sample/urdf/KR5/KR5 sixx R650.urdf");

Supported Formats

Format	Extension	Use Case
URDF	.urdf	ROS robots
SDF	.sdf, .world	Gazebo models
MJCF	.xml	MuJoCo models
SKEL	.skel	Legacy DART

Common Patterns

// URDF with package resolution
dart::io::ReadOptions options;
options.addPackageDirectory("my_robot", "/path/to/my_robot");
auto skel = dart::io::readSkeleton("package://my_robot/urdf/robot.urdf", options);

// Force specific format
options.format = dart::io::ModelFormat::Sdf;
