There are six agents that work can be allocated to: an extra-vehicular astronaut (EV), an intra-vehicular astronaut (IV), a Remote Manipulator System (RMS) (similar to the Canadarm), two humanoid robots (e.g., Robonaut), and the MCC. Based on reasonably assumed capabilities of each agent, we came up with six possible function allocations, as shown in Table 5.1. FA1 and FA2 are reasonably attainable with current capabilities, whereas FA3 to FA5 assume more futuristic capabilities of the robots. FA4-A and FA4-B differ in the allocation of responsibility for the robotic operations: in FA4-A, the IV astronaut is responsible, and in FA4-B the MCC is responsible. A communication delay of 10 seconds is assumed between MCC and the maintenance site, which could be representative of a spacecraft early in a transfer orbit to Mars.

Onboard the international space station (ISS), Robonaut 2 has undergone extensive tests as a humanoid robot intended for routine maintenance and cleaning tasks. Programmed in the Robot Operation System (ROS) framework, Robonaut 2 originally only consisted of a dexterous upper body capable of interacting with human-oriented tools, systems and devices inside the ISS. However, recently it has been equipped with a mobility platform that enables the robot to move around the ISS. It does so by gripping onto rails using snake-like manipulator legs (Badger, Gooding, Ensley, Hambuchen, & Thackston, 2016). The system is still a working development, but is progressing towards a fully-featured platform that will act as the foundation for future space robot missions.
