A gang of robots – one physical, several others voice-operated “virtual assistants” – is growing at the federal Department of Human Services, the department has revealed in a submission to a parliamentary inquiry on digital delivery of government services.

The department said it is planning to deploy assistant named Oliver and Gus, to “capture and send information to other applications and assist in processing.”

Another virtual assistant dubbed Roxy and based on Microsoft’s Cortana, is reportedly helping staff at Human Services process online claims.

Roxy is said to have so far answered some 95,000 questions since October, while its knowledge base spans some 6680 questions.

Then there’s Naomi: a physical robot based at the department’s technology innovation centre. The plan is for Naomi to “complement front-of-house services. helping people with directions and basic questions,” DHS said.
