This course surveys the development of robotic systems for navigating in an environment from an algorithmic perspective. It will cover basic kinematics, configuration space concepts, motion planning, and localization and mapping. It will describe these concepts in the context of the ROS software system, and will present examples relevant to mobile platforms, manipulation, robotics surgery, and humanmachine systems.

Course Preparation
This course is intended for advanced undergraduates and first year graduate students. I assume students have a rudimentary understanding of linear algebra, calculus, and are able to program in C++ and Matlab.
Goals and Evaluation
There will be five assignments and two exams. Grading will be 50% on the assignments and 25% for each exam. All students will need to use real robots by the of the term to earn their final mark.
Assignment due dates:
Assignment 1: February 20th 2020
Assignment 2: March 5th 2020
Assignment 3: April 2nd 2020
Assignment 4: April 16th 2020
Assignment 5: May 1st 2020
Midterm: Canceled
Final: May 6th 2020
Assignments are due by 23:59 EST on the day it is due. 10% per day of the grade is deducted for late submission. Deadlines are provided way ahead of time so work around them. Procrastinate at your own risk.

Week 13: Review
Honor Code: Above all, you must not misrepresent someone else’s work as your own. You can avoid this in several ways:
Regarding plagiarism:
The strength of the university depends on academic and personal integrity. In this course, you must be honest and truthful. Ethical violations include cheating on exams, plagiarism, reuse of assignments, improper use of the Internet and electronic devices, unauthorized collaboration, alteration of graded assignments, forgery and falsification, lying, facilitating academic dishonesty, and unfair competition.
In addition, the specific ethics guidelines for this course are:
 No teamwork or collaboration on assignments
 Public or private sharing of code, assignments and exams
Report any violations you witness to the instructor. You may consult the associate dean of student conduct (or designee) by calling the Office of the Dean of Students at 4105168208 or via email at integrity@jhu.edu. For more information, see the Homewood Student Affairs site on academic ethics: https://studentaffairs.jhu.edu/policiesguidelines/undergradethics
Read the Graduate Academic Misconduct Policy:
Examples of academic misconduct:
 Use of material produced by another person without acknowledging its source
 Submission of the same or substantially similar work of another person (e.g., an author, a classmate, etc.)

Intentionally or knowingly aiding another student to commit an academic ethics violation

Allowing another student to copy from one’s own assignment, test, or examination

Making available copies of course materials whose circulation is prohibited (e.g., old assignments, texts or examinations, etc.)
Teamwork for assignments is not allowed. You cannot use work from someone else (plagiarism). You cannot share your assignments to someone else (facilitating academic dishonesty).
 You cannot use any material from a classmate or student who took the course in previous semesters.
 You cannot share any material from this course in future semester.
Any academic misconducts (big or small) will be reported to Graduate Affairs (or Office of the Dean) and will be at least sanctioned by an “F” course grade. No negotiation. I will retroactively sanction plagiarism (i.e. a student plagiarize your assignment in future semesters).
