Complementary source code and data for the publication: Expressive Aliens - Laban Effort Factors for Non-Anthropomorphic Morphologies The source code includes the implementation of SAC reinforcement learning algorithm, reward functions based on Laban Effort Factors, and a gym environment for the PyBullet physics simulation. The implementation is based on PyTorch v1.8 and has been tested under Ubuntu 20.04 and Windows 10. Trained versions of the SAC algorithm as provided as serialised model weights and replay buffers. URDF files that specify the agent morphologies are also included.
