Academic year 2021-22 (second semester)
VERY IMPORTANT IN 2021-22. Please attend the first lectures of this course, starting with Monday, February 28, 2022, in order to get acquainted with the teaching organization. To book the presence in the classroom (room B2 of DIAG, building code RM102), see the Sapienza procedure. Also, please register as soon as possible (before the start of lectures!) to the Google Group of this course in 2021-22.
VIDEO LECTURES. The lectures of the course of the academic year 2019-20 have been fully video recorded and are available in the Robotics 2 playlist of the Video DIAG - Sapienza YouTube channel. More details in the Course material page.Course material
Booking of exams
Aims: This course provides tools for: Advanced kinematics and dynamic analysis of robot manipulators; Design of feedback control laws for free motion and interaction tasks, including visual servoing.
Contents: Advanced kinematics for robot manipulators (calibration, redundancy resolution). Derivation and use of the dynamic model of robots (Euler-Lagrange and Newton-Euler formulations). Identification of dynamic coefficients. Inclusion of joint transmission elasticity. Linear and nonlinear control schemes for set-point regulation (PD with gravity compensation, saturated PID, iterative learning, Cartesian/task regulation) and for trajectory tracking (feedback linearization and decoupling in the joint or Cartesian/task space, passive control, adaptive control) in free motion tasks, as well as for interaction tasks with the environment (admittance control, compliance control, impedance control, hybrid force/velocity control). Image- and position-based visual servoing (kinematic treatment). Diagnosis of robot actuator faults.
Courses of study: M.Sc. in Control Engineering (MCER), M.Sc. in Artificial Intelligence and Robotics (MARR)
ECTS Credits: 6 credits
Exams: written exam (+ oral examination, if needed); in alternative, after passing a midterm test, a project with written report and presentation

BREAKING NEWS. No class on Wednesday, March 2, 2022! To firmly protest against the war in Ukraine, we partecipate at 14:30 to the initiative Sapienza for peace.Note: Room B2 has 84 seats available, according to the current Covid-19 Phase 3 rules on social distance. For seat reservation, see the Sapienza procedure (the DIAG department in Via Ariosto 25 has building code RM102 of Sapienza).

"Robotics: Modelling, Planning and Control", 3rd Edition, Springer, 2009
Download the Errata Corrige for this book.
Only selected chapters are part of the course program, but this book is a perfect reference also for further studies. Other course material (PDF of the lecture slides, technical papers, data sheets, videos, texts of exams (with or without solution), exercises) is available in this page.
A Google group has been created to post questions about the content of the lectures, exchange information and discuss the topics of the course in general. New registrations are not accepted after the end of the lectures. Groups of past years are still active (but no new registrations are considered as well).
Access: Restricted to Sapienza students only. Please request admission at the URL using ONLY your institutional email address @studenti.uniroma1.it. When applying be sure to enter i) your first and last name as "Display Name", as well as ii) your Master program [Control Engineering (MCER) or AI & Robotics (MARR)] and iii) your current year of enrollment in the course of study, together with any other useful information, as "Reason for joining". Incomplete requests will be discarded without further notice.
I open sessions only for the exam Robotics 2 (code 1021883, 6 credits). For past versions and any other situation, please contact me in advance.
