Apollo is Apptronik's industrial humanoid — the design lineage runs through ten in-house generations and ten years of work on NASA's Valkyrie program before Apollo. The hot-swappable battery pack architecture is the deployment-tell: it's built around the assumption that a single charge cycle is shorter than a shift, and the operator is expected to swap rather than wait.
The Mercedes-Benz commercial agreement announced in March 2024 is the marquee pilot — Apollo runs assembly-kit delivery and component inspection at Berlin-Marienfelde. Apptronik describes the pilot as still pre-graduation: the partnership is live but hasn't moved beyond pilot scope publicly.
Honest caveat: Apptronik has not published degrees of freedom, walking speed, or onboard compute on the public Apollo product page. The values that ARE published — height, weight, payload, runtime — are vendor-quoted nominal figures.
