Undergraduate Machine Design Class Mechatronics Projects • Laparoscopic surgery • Rodent gait Trainer • Design and fabricate a robot trainer that uses 4 dc servomotors to guide end-points on prescribed paths • Write governing equations and program these • Grading based on novelty, fabrication, assembly, and Subject matter expert accuracy of the path Subject matter expert Dr. Dennis Fowler, CUMC Prof. Jack Martin, CUNY Sunil K. Agrawal, Ph.D., Professor Columbia University, New York, NY 10027 Email: Sunil.Agrawal@columbia.edu

Undergraduate Machine Design Class Project Logistics • Time-line – 1 month to design with an in-class presentation – 1 month to fabricate and test with an in-class demo • $100 budget to order small parts • Students have access to mill, lathe, laser cutter, and 3D printer • Mentored by instructor, TAs, lab manager, and lab technicians • NI-Labview-MyRio based testing platform with motors, associated electronics, and instrumented tools given to the students Sunil K. Agrawal, Ph.D., Professor Columbia University, New York, NY 10027 Email: Sunil.Agrawal@columbia.edu

Undergraduate Machine Design Class Learning Objectives • Understand the design process and limitations • Learn how electronics is integrated within machines • See how theory translates into practice and the effects of non-ideal conditions • Work in teams and understand group dynamics • Have a first exposure to design before Senior design • Experience the thrill in creating a working design Sunil K. Agrawal, Ph.D., Professor Columbia University, New York, NY 10027 Email: Sunil.Agrawal@columbia.edu

Undergraduate Machine Design Class Sample Projects Sunil K. Agrawal, Ph.D., Professor Columbia University, New York, NY 10027 Email: Sunil.Agrawal@columbia.edu

Concluding Remarks • Students love integration of mechanical design with electronics and programming • Fun learning environment for the students motivated by a human application • Logistic Challenges for the students and instructors to grasp multi-disciplinary concepts • Collaborative group experience for students is a great plus during interviewing.
