The world increasingly relies on robots to deliver speed (e.g., industrial process automation), precision (e.g., in automotive welding) and safety (e.g., in defense/surgery). To make robots as robust as possible requires precise modeling using simulation on all three subsystems: (1) an assembly of bodies typically linked by joints, (2) power electronics/actuators to drive the mechanism/s and (3) controllers that ensure predictable, desired motion. This work shows the workflow in Ansys for a successful design of your robot, not only in terms of multi-body dynamics, but also of system control by integrating it in a full system simulation. This approach allows engineers to analyze its product from system to assembly to component level, giving a deep insight and helping them to find problems before they become an issue.
