🔨 Model Building Module#
MotrixSim provides a programmatic model building API for loading, transforming, and combining multiple models before simulation.
Main Features#
Model Loading: Support for MJCF/URDF/MSD formats
Model Combining: Attach multiple models together
Transform Operations: Set translation, rotation, name prefix/suffix
Application Scenarios#
Multi-robot scene construction
Dynamic end-effector assembly
Runtime model composition
