In human-robot teams where agents collaborate together, there needs to be a
clear allocation of tasks to agents. Task allocation can aid in achieving the
presumed benefits of human-robot teams, such as improved team performance. Many
task allocation methods have been proposed that include factors such as agent
capability, availability, workload, fatigue, and task and domain-specific
parameters. In this paper, selected work on task allocation is reviewed. In
addition, some areas for continued and further consideration in task allocation
are discussed. These areas include level of collaboration, novel tasks, unknown
and dynamic agent capabilities, negotiation and fairness, and ethics. Where
applicable, we also mention some of our work on task allocation. Through
continued efforts and considerations in task allocation, human-robot teaming
can be improved.Comment: Presented at AI-HRI symposium as part of AAAI-FSS 2022
