VoLo: Why VLA Tool Orchestration Helps Long-Horizon Manipulation
Can a robot become more reliable by treating its vision-language-action policy as a tool rather than its entire controller? This episode explains how VoLo combines language-model orchestration, visual monitoring, and physical recovery to improve long-horizon manipulation. We cover three questions: how the agent interrupts and redirects a running policy; what the simulation ablations reveal about orchestration versus additional tools; and whether the hardware results establish an advantage for the complete hybrid architecture. The system combines π0.5 with perception and grasp/place…
