R2D-RL: A RoboCup 2D Soccer Environment for Multi-Agent Reinforcement Learning

arXiv:2606.18786v1 Announce Type: new Abstract: Robot soccer is a challenging testbed for multi-agent reinforcement learning because it combines partial observability, cooperative and adversarial interaction, sparse rewards, and long-horizon tactical behavior. RoboCup 2D Soccer Simulation (RCSS2D) provides a mature robot-soccer platform, but its competition-oriented server-client architecture is difficult to use directly with modern Python-based MARL workflows. We introduce R2D-RL, a reinforcement learning environment that connects RCSS2D and HELIOS-based player clients to a Python MARL interf

Why this matters
Why now

The continuous advancements in multi-agent reinforcement learning (MARL) necessitate more robust and accessible test environments for complex, real-world-like scenarios.

Why it’s important

Accessible robotic simulation environments like R2D-RL accelerate MARL research and development, which is crucial for advancing AI agent capabilities in dynamic, interactive settings.

What changes

This simplifies the integration of a mature robotic soccer platform with Python-based MARL workflows, lowering the barrier to entry for researchers and expediting algorithmic innovation.
