Abstract

Cable-driven manipulators are used in applications like rehabilitation devices, assistive exoskeletons, and lightweight manipulators due to low inertia, high force transmission capability, and flexible design architecture. Since cables can only transmit tensile forces, the ability of these systems to generate the desired wrench is limited to the tensionable workspace where all cables remain under positive tension. The size and shape of this workspace depend on the cable attachment points on the robot links. Optimizing these parameters is important for improving the operational capability of cable-driven manipulators. This work presents a Genetic Algorithm (GA) based optimization framework to determine optimal cable attachment parameters that maximise tension feasibility along a predefined joint trajectory. The study considers a planar two-link serial manipulator actuated by four cables. Cable attachment geometry is defined using two parameters the distance from the joint center along the link (d) and the offset distance from the link axis (h). The proposed optimization method identifies cable attachment parameters that ensure positive cable tensions within specified bounds throughout the trajectory, thereby improving the system’s tensionable workspace.
