Embodied Playground: A Long-Horizon Agentic Robotics Benchmark for Physical, Strategic, and Spatial Reasoning

Embodied Playground contains 410 simulated environments. In a Tower of Hanoi task, for example, the robot has to plan a sequence of moves and follow the stacking rules at every step. Reaching the target arrangement only counts if the moves that got it there were legal.

For a smaller evaluation, we selected 100 tasks across five suites for EP-100. Each task has four starting conditions. The protocol specifies what an agent can observe and which tools it can use, and checks its actions as well as the final state.

The benchmark code is available on GitHub.
