A few years ago, Kevin Lynch invited a small group of researchers interested in motion planning and control of mechanical/robotic systems to visit Northwestern University. This small, informal meeting gave us an opportunity to discuss our latest ideas and also attempt to bridge some of the gaps between control/mechanical engineering and algorithms/computer science. It was also a nice opportunity to build new relationships and collaborations. The meeting was so valuable to us that we have continued to meet every year. This brings us to the 4th Midwest Mechanical Motion Meeting (M^4) which will be at the University of Illinois at Urbana-Champaign. We plan to have about a dozen researchers describe their current projects and following each presentation will be a discussion. Attendees are also encouraged to come a day early, on Friday, September 6, for lab visits, meetings with other UIUC faculty, and/or socializing with other M^4 participants.

• The meeting will take place at the Beckman Institute, University of Illinois
• Location of the Beckman Institute on campus maps.
• Location of the Beckman Institute using Mapquest (405 N. Mathews Ave., Urbana, IL 61801).
• Registration: Free!
• Hotel information
• Arrival information: On the morning of the workshop, you should be able to park for free in Lot B4, which is directly east of the Beckman Institute. Also, many of the meters should be free because it will be Saturday. If you find one, you could park much closer (be sure to read the meter times before parking). You should enter the Beckman Institute from the east entrance, which is the one visible from the parking lot. The blue region on this map leads directly to the east entrance. The door will probably be locked, but someone should be waiting there to let you in. The meeting will take place in Room 2269.
