The safety suite includes SIL 2-rated controllers and a modular fall-arrest harness that anchors to ceiling rails. Apptronik worked with TÜV Rheinland to validate the architecture, including fault detection on battery packs and actuators.

Petrochemical operator LyondellBasell is piloting Apollo for valve inspections in Houston, where heat and wind complicate drone or AMR-based approaches. The humanoid reads gauges, manipulates wheels and feeds data back into the plant's digital twin.

Apptronik plans to open a developer program in early 2026 so customers can build skills that take advantage of the redundant safety layer. The company is bundling remote telepresence so subject-matter experts can supervise from control rooms.
