Course Goals

This course serves as a technical elective for computer engineering and electrical engineering majors. The goal of this course is to introduce students to the basic concepts in robotics that (a) provide prerequisite knowledge for follow-on courses, (b) provide essential knowledge of the field that would be required by a practicing engineer who must deal with automation, and (c) provides professional development by introducing best practices and ethical considerations for engineering design. This course includes a significant laboratory component.
