Continuing Progress

We had a film crew in and around the garage on Thursday, April 2, to take footage for a video that will be shown at the upcoming dedication ceremony for the Keller Center for Innovation in Engineering Education. PAVE will be one of several student projects featured in the video. Pictures from the video shoot will be posted shortly.

In addition, all of our new components for the IGVC robot have arrived and we have a long weekend ahead of us, reassembling the robot so we can get started with software testing.

Upcoming Events

We are keeping ourselves quite busy trying to get the robots up and running for the events coming up next month. More information is available on our events page.

March 30: Engineering Open House
P12 will be on display in front of the Friend Center for upcoming engineering students to view.

April 2: Hitting the Big Screen
The PAVE garage and our robots will be filmed as part of video for the upcoming dedication of the Keller Center for Innovation in Engineering Education.

April 4: High School Colloquium
We will be presenting at the Society of Women’s Engineering (SWE) upcoming colloquium, to encourage high school students, especially women, to enter fields of engineering. Our robots will also be on display.

April 17/24: Princeton Preview
We welcome prospective Princeton undergraduate students by displaying our robots and giving tours of our garage. We hope to recruit the incoming student to Princeton Engineering and especially into PAVE

April 24 (1:45 – 3:30): Local Middle School Visit
We will be visiting Mrs. Weinberger’s robotics class at Montgomery Middle school. While there, we will be displaying P12, as part of the middle school students’ unit on the DARPA Grand Challenges. We will also have Arogs displaying its GPS waypoint-following abilities on a course created by the students.

New Website Layout

For the past week or so, we’ve been working on a new layout for our homepage. Hope you enjoy it! The new layout accompanies our transition to Web 2.0 -you can now follow our incremental progress updates through Twitter, view photos from projects and events on our flickr page, see videos on our YouTube channel, and become a fan on facebook.

We have many exciting events coming up over the next couple of months and a lot of progress to make on our projects. Be sure to check back often for progress updates, photos and more!

We’re Going Social!

PAVE has been slowly expanding its presence to Twitter, Facebook, YouTube, and Flickr. We’ve recently added the links to our various social profiles and pages can also be found at the top of the sidebar. We’ll be constantly adding content to our accounts on YouTube and Flickr, as well as tweeting on our Twitter when we make progress. As always, we will continue to regularly update our site with news and upcoming events.

We’ll be adding more “Web 2.0” features to our site in the coming weeks so check back to see the changes.

PAVE at the 2009 NYC FIRST Regional Competition Career Expo

PAVE team members answer questions about their projects at the 2009 NYC FIRST Regional

PAVE was at the 2009 NYC FIRST Regional Competition from March 7 to March 8, 2009. This is the second year that we have been invited to exhibit at the competition’s career expo. This gave us a chance to show Prospect 12 and our build-in-progress robot for the 2009 IGVC to hundreds of middle- and high-school students from the greater New York City area. Team photo after the break. Continue reading PAVE at the 2009 NYC FIRST Regional Competition Career Expo →

New Vision for the IGVC


The PAVE Vision team has begun gearing up for the 2009 IGVC. We will be continuing our stereo-vision approach to obstacle and lane detection, and this year we will be using a Videre Design STOC (Stereo On Chip) color stereo camera. This camera’s innovative design includes an onboard Xilinx Spartan 3 FPGA that can stream live disparity maps to the PC. This frees up resources on our computer for depth map analysis and all the other processes that control the robot.

The image above shows a sample frame from the camera. The source image is at the bottom-left, and the disparity map calculated onboard the camera is shown at the bottom-right. The center window shows the 3D reconstruction of the scene, with the source image mapped onto the point cloud reconstructed from the disparity map.

As the semester progresses, the Vision team will provide updates on the modifications we are making to improve our obstacle and lane detection systems. We look forward to demonstrating our single-sensor approach again at the competition, and hope to make our system even more successful than last year.

PAVE Presents at SPIE/IS&T Electronic Imaging Conference

Several PAVE students were invited to present their paper, Kratos: Princeton University’s Entry in the 2008 Intelligent Ground Vehicle Competition at the 2009 SPIE/IS&T Electronic Imaging Conference on Tuesday, January 20th. The conference, which was held in San Jose, CA from January 18-22, brought together professional and academics in a variety of fields relating to computers, digital imaging and their applications.

PAVE seniors Chris Baldassano, Gordon Franken and Jonathan Mayer presented the paper as part of the Intelligent Robots and Computer Vision sub-conference. The submitted paper was a revised version of the technical paper for which PAVE’s 2008 IGVC team won a first place design award. The work was co-authored by Andrew Saxe ’08 and Derrick Yu ’10, and advised by Professor Robert Schapire of the Computer Science Department.

Princeton ACM/IEEE Chapter Meeting

On Thursday, November 20, PAVE was the featured presenter at the monthly meeting of the joint ACM/IEEE, Princeton Chapter. At the auditorium on the Sarnoff Corporation campus, PAVE gave an hour-long presentation, filled with videos, photos and stories about all of our past projects, including the 2005 and 2007 Grand Challenges, the 2008 IGVC, as well as ongoing research. Afterwards, the attendees met the PAVE members and examined Prospect 12, which was on display for the event.
