While browsing a recent issue of Make magazine, I found a list of CNC projects that caught my eye. In particular, the wood and aluminum bottle opener appeared to be ripe for customization with a bit of laser etching. The first step was to determine what art to use for the laser etching. With the approaching departure of a longtime colleague, I decided to go for a bit of robot art to make the opener into a personalized going away gift.
Four blog posts later and we’ve arrived at the last nostalgia blog post in the series. Ready for the story about the air hockey table that grew a Lynxmotion robot arm and learned how to play? Great! In the fall of 2004, I signed up to take a Video Processing course as a follow-up to the Digital Image Processing (DIP) course I had taken with Dr. Oge Marques (Blog – Twitter). As with the DIP course, the Video Processing coursework included a term project of our choosing. I decided that it would be interesting to extend the functionality of the DIP project somehow but was not sure quite what to do. At some point along the way during the brainstorming, I remembered a robotic air hockey table I had seen when I was touring a college a few years back. That particular robotic air hockey table worked by using sensors embedded in the table surface to locate the puck as it moved and feeding that information to a robot arm. I decided to see if I could simply the idea by replacing the embedded sensors with a cheap USB web camera …
In 2005, as part of a graduate course on robotics, the team of Melissa Morris, John Morris, Thomas Kelly and I set about repurposing a JOT automation system (http://www.jotautomation.com/) which housed a four axis Hirata robot (http://www.hirata.it/) and was donated to FAU from Motorola. The system, pictured below, was originally used to print and apply barcodes in the battery compartment of cellular phones. The goal of the repurposing was to complete a project whereby the system would be converted into a pipetting robot, capable of dispensing liquids into 96-well microtiter plates. This was accomplished on an extremely lavish budget of $0.
As part of the Scripps Florida grand opening celebration in 2009, the volunteer robotics team at Scripps Florida was tasked with repurposing a laboratory robot for use as demonstration unit and an Educational Outreach platform. This volunteer team consisted of Lina DeLuca, Dr. Louis Scampavia and myself. The goal of this project was to create a hands-on robotic system which could be used to showcase the unique technology used in the drug discovery process and more generally, to generate interest in science and engineering.
As the second post of the series and representing another nostalgic trip down memory lane, this post is dedicated to the first robotic vision system that I ever built.
