Abstract
The article considers the application of numerical method based on bicentered Krawczyk operator for solving the problem of the robot workspace approximation with box constraints. We applied several modifications for approximation of the solution sets of the indeterminate system of nonlinear equations and compare it with basic method. All methods were tested on a passive orthosis robot, which is part of the lower limb rehabilitation system. A mathematical model of the mechanism kinematics is presented. We evaluate the efficiency of the considered approaches, compute and visualize the robot workspace for different parameters sets.
