## Description

The objective of this course is for students to develop the ability to recognize, formulate, and solve control problems within the context of robotic applications. We will introduce important concepts and tools for design and analysis of advanced robotic control systems. Topics include advanced rigid body kinematics and dynamics using product of exponentials, screw theory, and spatial vectors, nonlinear dynamical systems, Lyapunov stability, feedback linearization, optimal control and trajectory optimization, model predictive control, among others. An emphasis will be placed on developing competency in control and optimization theory and on applications within robotics.

## Objectives

- Develop solid analytical skills to conduct cutting edge research in control theory and robotics
- Train the student’s ability in formulating robotic control problems through optimization
- Develop advanced understanding in multibody dynamics using product of exponential, spatial vectors, and screw theory
- Develop good theoretic foundations on advanced control methods that are commonly used in robotics, including feedback linearization, optimal control, trajectory optimization, DDP, reachability, and MPC
- Use the theory learned in class to solve research problems of interest
