ME 327: Design and Control of Haptic Systems

Welcome

Welcome to ME 327: Design and Control of Haptic Systems. In this class, we will study the design and control of haptic systems, which provide touch feedback to human users interacting with virtual environments and teleoperated robots. This class is aimed toward graduate students and advanced undergraduates in engineering and computer science. This class requires a solid background in dynamic systems and programming. Experience with feedback control and mechanical prototyping is also useful. Attendance is required if you are taking the class; guests/auditors are welcome. Course information and policies are contained in the syllabus. (Note that the final lecture schedule, assignment due dates, etc. are given on this web page; dates and topics listed in the syllabus are tentative.) This course focuses on device modeling (kinematics and dynamics), synthesis and analysis of control systems, design and implementation, and human interaction with haptic systems. For a course focused more on 3D haptic rendering, CS 277 Experimental Haptics is also taught. (However, the instructors of ME 327 and CS 277 do not want you to take these courses -- or any other major project class -- simultaneously due to the intense work involved in the final project.)

The primary instructor is Allison Okamura, Associate Professor in Mechanical Engineering at Stanford University. Allison has been a professor in the fields of haptics and medical robotics for about 13 years. The course assistants are Andrew Stanley and Zhan Fan Quek, Ph.D. students in Mechanical Engineering with extensive experience in haptic device design, control, and human-user evaluation.

Assignments

The dates below show when the assignment is distributed. Assignments will usually be due one week after distribution (the due date will be written on the assignment), and can be submitted in class or to the ME 327 dropbox outside the door to the area where Allison's office is. (Access to solutions is restricted to students in the class; if you are not in the class and wish to see the solutions, email Allison and please explain who you are and what you will use the solutions for.)

3/31Background survey
4/4 Assignment 1: Hapkit device modeling and construction (Hapkit Solidworks Files, Hapkit Parts List, Hapkit Assembly Instructions, Problem 4 MATLAB template, Assignment 1 Solutions)
4/11Assignment 2: Rendering on a Kinesthetic Haptic Device (Hapkit Arduino code template, Hapkit/Arduino information for novices, Hapkit Board pin mapping)
4/18Assignment 3: Haptic Controls and Vibration Feedback
4/25Assignment 4: Teleoperation and Graphic Display

Students in the class will create and use their own versions of Hapkit, a new haptic device created specifically for haptics education.

Presentation

Paper comprehension and presentation are important skills for research and development, and paper presentations will introduce the class to a wide variety of haptic systems. Each team will give one 25-minute paper presentation/activity (10-minute talk, 5-minute Q&A, 10-minute activity) to the class.

Project

The project is to develop a novel haptic system for understanding human perception and performance in virtual or teleoperated environments. The project must include bidirectional haptic interaction between a person or a robot and a real, remote, or virtual environment, and a corresponding experiment to characterize human/system capabilities.

Final project demonstrations will occur at a "Haptics Open House" tentatively scheduled for Friday, May 30 from 2:30-4:00 pm in the Gates Robotics Lab. The project demonstrations will be joint with CS 277: Experimental Haptics.
