ARACHNIS: Analysis of Robots Actuated by Cables with Handy and Neat Interface Software

Abstract : This paper presents ARACHNIS, a graphical user interface for the analysis and parametric design of Cable Driven Parallel Robots~(CDPRs). ARACHNIS takes as inputs the design parameters of the robot, the task specifications, and returns a visualisation of the CDPR Wrench Feasible Workspace~(WFW) and Interference-Free Constant Orientation Workspace~(IFCOW). The WFW is traced from the capacity margin, a measure of the robustness of the equilibrium of the robot. Interferences between the moving parts of a CDPR are also determined by an existing technique for tracing the interference-free workspace of such robots. Finally, the WFW and the IFCOW of a planar cable-driven parallel robot and of a spatial cable-driven parallel robot are plotted in order to demonstrate the potential of ARACHNIS.
