This paper presents an approach for approximating the reachable space of robotic manipulators based on convex polytopes. The proposed approach predicts the reachable space over a given time horizon based on the robot’s actuation limits and kinematic constraints. The approach is furthermore extended to integrate the robot’s environment, assuming it can be expressed in a form of linear constraints, and to account for the robot’s link geometry. The accuracy of the proposed method is evaluated using simulations of robot’s nonlinear dynamics and it is compared against the cartesian space limits, usually provided by manufacturers in standard datasheets. The accuracy analysis results show that the proposed method has good performance for the time horizons up to \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$t_h\!\le $$\end{document}250 ms, encapsulating most of the simulated robot’s reachable space while maintaining comparable volume. For a 7 dof robot, the method has an average execution time of 50ms, independent of the horizon time, potentially enabling real-time applications.
