Abstract
The European Robotic Arm (ERA) is a seven degrees of freedom relocatable anthropomorphic robotic manipulator system, to be used in manned space operation on the International Space Station, supporting the assembly and external servicing of the Russian segment.
The safety design concept and implementation of the ERA is described, in particular with respect to the central computer’s software design. A top-down analysis and specification process is used to down flow the safety aspects of the ERA system towards the subsystems, produced by a consortium of companies in many countries; the user requirements documents and the critical function list are the key documents in this process. Bottom-up analysis (FMECA) and test, on both subsystem and system level, are the basis for safety verification. A number of examples show the use of the approach and methods used.
