The University of Manchester Uses MapleSim in Robotics and Control Systems Courses

Dr. Joaquin Carrasco, Professor of Control Systems at the University’s School of Electrical and Electronic Engineering, has taught various Control Systems courses to Master’s students in the Master of Science in Advanced Control and Systems Engineering program for the past six years. He has received overwhelmingly positive student feedback from using Maple T.A., the powerful online testing and assessment system from Maplesoft, in his Control Systems classes. He has also recently incorporated Maplesoft’s MapleSim and the MapleSim CAD Toolbox into his Robotics courses. With the MapleSim CAD Toolbox, students can see how their mechanical CAD models behave as part of a larger, multidomain system.
