The Canadian Space Station Remote Manipulator System (SSRMS) that consists of 7 joints has been in operation since 2001 aboard the International Space Station (ISS). The extensive operational experience of the Space Shuttle's Remote Manipulator System (SRMS), which has 6 joints, played a significant role in the design and operation of the ISS robotics. However, optimization of the ISS robotics operation for different types of tasks utilizing the unique redundancy characteristics of the 7-joint systems is still underway. In this study, we have proposed three evaluation indices for multi-joint arm configurations in order to avoid collision with surrounding structures. Based on the evaluation of operations of the SSRMS a demonstration model, it has turned out that the proposed indices are beneficial for enhancing clearance monitoring of the arm with respect to the surrounding structures. Furthermore we have proposed an operation support display to contribute to the operational safety and mission success.
