$x[n+1] = x[n] + \gamma(u[n]-x[n]) - K_P\sum_{j=1}^N(\frac{1}{N}x_j[n]) + K_I\sum_{j=1}^N(\frac{1}{N}w_j[n])$

$w[n+1] = w[n] - K_I\sum_{j=1}^N(\frac{1}{N}x_j[n])$

Class 1 (W 9/20)

Welcome to the course and course website. Structure of the course (HW due Wed, student-generated lectures and learning materials, in-class assignments, feedback on student lectures, occasional Friday quizzes). Book, software, (lack of) D-H parameters, syllabus, V-REP simulator, office hours.

At home:

Videos: first 3 videos of Chapter 2, through Chapter 2.2
Software: download github software with book, install V-REP and verify that you can use Scenes 1 and 2 (the UR5)
HW1, due 1:30 PM 9/27: Exercises 2.3, 2.9, 2.20, 2.29. Also, create your own example system with closed loops, something not in the book, and solve for the degrees of freedom using Grubler's formula. Make it something that exists or occurs in common experience, not necessarily a robot. Imagine using it to teach someone about Grubler's formula.
