Assumption that Increments 29/30 and 31/32 objectives are completed; initial communication and camera tests to establish SPHERES as a mobile camera platform.
A key objective of the Human Exploration Telerobotics-Smartphone (HET-Smartphone) project is to assess how intravehicular activity (IVA) free-flyers
improve the efficiency and productivity of human explorers, and increase the return (scientific, engineering, etc.) of human missions. To do this, HET-Smartphone conducts detailed experimentation and analysis of SPHERES/Smartphone remotely operated by ground controllers on Earth and crew on ISS. The results of these tests provide insight into the requirements, benefits, limitations, costs and risks of integrating telerobotics into future space exploration campaigns.
Future human missions to the Moon, Mars, and other destinations offer many new opportunities for exploration. But, extra-vehicular activity (EVA) is always limited due to consumables (e.g., oxygen), crew size, and the amount of ?utilization? time. Robots, however, complement human explorers, performing work under remote control from a crew vehicle, or even from Earth. A central challenge, therefore, is to understand how human and robot activities are coordinated to maximize crew safety, mission success and scientific return.
Robots do a variety of work to increase the productivity of human explorers. Robots perform tasks (survey, inspection, etc.) that are tedious, highly repetitive or long-duration. Robots perform work that is beyond human capability, such as operating in dangerous environments. Robots perform precursor work, such as scouting, that helps prepare for future human activity. Robots also perform ?follow-up? work, completing tasks designated by, or started by, humans.
The HET-Smartphone experiments:
HET-Smartphone identifies and quantifies requirements, architecture, operations concepts, costs and risks associated with telerobotic operations of free-flyers for future human exploration missions.Earth Applications
HET-Smartphone explores many aspects of human-robot interaction including high-level control of robots over large time delays and limited bandwidth. Findings from these experiments benefit other earth based telerobotics tasks such as robot-assisted surgery, bomb squad robots, and remote industrial inspection.
