Comprehensive open-source agentic robotics framework treating VLMs/LLMs as code-generating APIs for perception (SAM3, Molmo) and control (IK, grasping), with CaP-Gym benchmark of 187 diverse manipulation tasks (tabletop, bimanual, mobile; sim/real) and CaP-Bench evaluating 12 frontier models; demonstrates rapid RL gains (7B model from 20% to 72% success) with strong sim-to-real transfer.
