HAL, the Harmoni AI Lieutenant, brings context-aware AI directly to frontline manufacturing workers through the Harmoni device installed at each work center. HAL knows who the operator is, which machine they are using, what job and part they are producing, which program is running, what engineering and quality requirements apply, performance, physical location, and relevant history. It dynamically brings together the information needed from work instructions, programs, check sheets, attachments, ERP and MES records, schedules, machine telemetry, alarms, RFID data, and historical outcomes. Operators communicate through multilingual voice, text, or an illuminated push-to-talk control. HAL can answer job-specific questions, diagnose problems, calculate performance, predict scrap, recommend process changes, generate schedules and reports, and carry out authorized Harmoni tasks such as creating requests, completing labor transactions, establishing alerts, and sending notifications. Every write requires human confirmation. HAL is also available through the cloud for engineering, quality, production control, and management.
