Contents

Motion and manipulation are key issues in the field of robotics and automation, but they also play a major role in virtual environments and games. We will study models and planning problems for tasks that involve motion or manipulation. The course will provide a solid basis in kinematics, which studies the motion of a body without taking into account its mass or the forces acting on it. We will consider representations of rotations, orientations, and rigid transformations. Our study of manipulation concentrates on forward and inverse kinematics for articulated structures such as arms, models for grasp analysis based on velocities and forces, and on simple non-prehensile forms of manipulation such as pushing. In addition we will focus on the fundamentals of control and sensing, configuration spaces, and collision detection.

Literature

Parts of Chapters 1, 2, 3, 4, 5, 6, 13, and 15 of the book Theory of Applied Robotics by Reza N. Jazar (which can be read online at Utrecht University), parts of Chapters 2, 3, 4, 5, and 7 of the book Mechanics of Robotic Manipulation by Matthew T. Mason, parts of Chapters 1 and 2 from the no longer available book Fundamentals of Robotics: Analysis and Control by Robert J. Schilling, and parts of Chapters 3 and 4 from the book Collision Detection in Interactive 3D Environments by Gino van den Bergen. These chapters are supplemented by slides and class-room notes. Copies of the relevant pages of the book by Schilling are available for reference, and copies of the relevant pages of the book by Van den Bergen are also available for reference

Exam form

The final grade depends on a written test (60 %), a practical exercise about inverse kinematics (20 %), and two homework exercises about calculus and linear algebra (10%) and configuration spaces (10%).

Written test

The test covers all material treated in class plus all designated chapters from the aforementioned books. The grade for the written test should be at least 5.0 to pass the entire course. An example of a written test can be found here, along with the supplementary figure for exercise 4.

Practical exercise

The practical exercise considers forward and inverse kinematics for a human finger. The description of the exercise can be found here. You are free to choose any of the fingers. The exercise can be carried out in pairs. Send an email to the teacher to register your team. A short 5-page (at least 2500-word) report should be written about the modeling steps and the experimental findings. The grade for the practical exercise should be at least 5.0 to pass the entire course. The practical exercise will be distributed on Wednesday October 4. The deadline for handing in the report is Wednesday October 25 at 15:15. You can also submit a video that illustrates your solver by sending it to Ioannis Nemparis at I.Nemparis@uu.nl.

Homework exercises

The first individual homework exercise concerns essential calculus and linear algebra (for the Game and Media Technology master program). The exercise will be distributed on Friday September 15. The deadline for handing in your handwritten solutions is Wednesday September 20 at 15:15.

The second individual homework exercise considers relevant notions in configuration space. The exercise will be distributed on Friday October 13. The deadline for handing in the solutions is Wednesday October 18 at 15:15.
