Modern Robotics, Course 2: Robot Kinematics

Northwestern University

Embark on a journey into the intricate world of robotics with the "Modern Robotics, Course 2: Robot Kinematics." This comprehensive course delves into the fundamental mathematical modeling techniques crucial for understanding how robots operate. Through this specialization, you will gain the essential knowledge and skills needed to pursue a career in robotics or advanced studies in the field.

Throughout the six short courses comprising this specialization, you will explore various aspects of robot kinematics, with Course 2 focusing on Robot Kinematics. The course covers topics such as forward kinematics, velocity kinematics and statics, inverse kinematics, and kinematics of robots with closed chains. You will leverage the product-of-exponentials formula to solve forward kinematics, understand the relationship between joint velocities and forces/torques, and learn to calculate joint values for achieving desired hand configurations.

Utilizing the textbook "Modern Robotics: Mechanics, Planning, and Control" by Lynch and Park, and a library of robotics software in Python, Mathematica, or MATLAB, you will delve into practical applications and utilize the free cross-platform robot simulator V-REP. This enables you to work with state-of-the-art robots and gain hands-on experience in the comfort of your own space, without any financial investment.
