HygieneRoboBench tests whether robot plans remember contamination

A new benchmark separates safe task completion from efficient resource use.

Listen to this article

Researchers introduced HygieneRoboBench in an October 6 preprint to test whether household robot planners remember contamination from earlier contacts. The benchmark contains 624 cases across 134 task families, spanning activities including cleaning and laundry.

Tasks ask planners to continue after previous actions or new contact events while respecting resource limits and user priorities. A washed gripper can become contaminated again.

Planning before physical testing

The authors combine language interpretation, contact history reconstruction and a constraint solver in their companion planner. It recorded 94.4 percent safe resolution and 90.4 percent optimal safe resolution overall. Both measures count correct rejection of infeasible tasks.

Those scores concern explicit rules and modeled costs. Physical execution with measured contamination and cleaning outcomes remains future work. The planner also did not lead every comparison.
