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 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 covers device modeling (kinematics and dynamics), synthesis and analysis of control systems, design and implementation of mechatronic devices, and human-machine interaction. For a course focused more on 3D haptic rendering and integration with graphics, CS 277 Experimental Haptics is also taught occasionally (although no offering us currently planned).

The primary instructor for ME 327 is Allison Okamura, Professor in Mechanical Engineering at Stanford University. The course assistants are Nathan Usevitch and Jake Suchoski, both Ph.D. students in Mechanical Engineering.

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 box 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.)

1/9Background survey
1/11Assignment 1: Introduction to Haptics and Kinesthetic Haptic Devices (Matlab template for problem 4, Hapkit Solidworks files, Solutions)
1/18Assignment 2: Assembly and Testing of a Kinesthetic Haptic Device (Hapkit parts list, Hapkit assembly instructions, Hapkit Arduino code template, Solutions)
1/25Assignment 3: Haptic Rendering (Updated Hapkit Arduino code template, Solutions)
2/1Assignment 4: Haptic Controls and Vibration Feedback (Solutions)
2/8Assignment 5: Teleoperation and Graphics(Example Processing code, Solutions)

Students in the class will create and use their own versions of Hapkit, a haptic device created specifically for haptics education. Note: For this class, use only Hapkit information posted on the ME 327 website, because it is different from that on the Hapkit website.

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. The project must include bidirectional haptic interaction between a person or a robot/agent and an augmented, remote, or virtual environment, and a corresponding experiment to characterize human/system capabilities.
