The Story About Raven

rosenSLUG REPORT > Collaboration was key to new open sourced surgical robots

“The story about Raven is actually the story about collaboration.”

These words rang out long after my recent interview with Jacob Rosen, an associate professor of computer engineering in the Jack Baskin School of Engineering at UC Santa Cruz. Rosen and his research group have been working alongside Blake Hannaford, director of bio-robotics of the University of Washington (UW), to create Raven II, a robotic surgery system that relies upon Rosen's choice word: collaboration.

 

Cooperation between surgeons and engineers is “probably the only way you can design, fabricate, or create any surgical medical device,” says Rosen, and is directly responsible for the creation of the Raven system.

“It all started in the mid-90s … we started to look at surgery and study objective assessments of surgical skills from a mathematical perspective—that is to say developing algorithms that can assess skills in an objective way—and from that study we were able to create a foundation for Raven I,” says Rosen.

Now, several years later, the two groups’ hard work is finally paying off with the recent completion of seven Raven II systems. Five of the systems will be sent to some of the top medical research facilities in the country: Harvard University, John Hopkins University, University of Nebraska, UC Berkley, and UCLA. The last two systems will stay with UCSC and UW. All seven systems, once delivered and installed, will also be networked together over the Internet in order to conduct collaborative experiments.  

“We have a stable system that can be duplicated and shared between other people operating in the field, which is important because one of the problems for people studying surgical robotics is that the research platforms are very limited and usually not accessible,” says Rosen. “The idea is to create an open source platform, both hardware and software, that anyone can change, in order to accelerate research and stimulate collaboration.”

Rosen cites Robert Aumann, an Israeli-American mathematician and member of the United States National Academy of Sciences, whose studies into the prisoner dilemma, a concept within game theory that shows why two individuals may never want to cooperate, influenced Rosen and his team's research.   

“What [Aumann] discovered was that if two people played the situation out multiple times, the outcome was different than if you just play once.  And so his conclusion ... showed that if two companies who are evenly competing within the same market collaborate, they will both make more money,” Rosen explains.

The difference between the men, however, is that Rosen is interested in the way in which two surgeons can work together mainly through the means of robotics in the operating room. The Raven II system was specifically designed for minimal invasive surgeries, which are surgeries where small incisions in the body are made in order to allow small tools and, in many cases, cameras to pass through them so that surgeons can see and operate on the inflicted area underneath the skin. The Raven II is comprised of a surgical robot with two arms, a camera for viewing the operating area, and a surgeon interface system.

Rosen hopes that surgeons, as well as engineers, will be open to using this new technology in the collaborative manner that produced it.

“There is sort of a notion of collaboration embedded in many of the things that we do,” he says, “and [sometimes] as territorial animals, it is hard for us to accept them, but it tends to work.”

Gemini Sun, Pentecost, Shavuot—Enlightenment and Gladness

As the sun enters Gemini on Sunday, sign of speaking, communication, thinking, inter-relations, writing and understanding languages, the feast days of Pentecost & Shavuot (Catholic and Jewish festivals) occur. During Pentecost’s 50 days after Easter, tongues of fire appear above the heads of the disciples, providing them with the ability to understand all languages and all feelings hidden in the minds and hearts of humanity. It’s recorded that Pentecost began with a loud noise, which happened in an upper room (signifying the mind). The Christ (World Teacher) told his disciples (after his ascension) when encountering a man at a well carrying a water pot (signs for Age of Aquarius) to follow him to an upper room. There, the Holy Spirit (Ray 3 of Divine Intelligence) would overshadow them, expand their minds, give them courage and enable them to teach throughout the world, speaking all languages and thus able to minister to the true needs of a “seeking” humanity. Pentecost (50 days, pentagram, Ray 5, Venus, concrete and scientific knowledge, the Ray of Aquarius) sounds dramatic, impressive and scary: The loud noise, a thunderous rush of wind and then “tongues of fire” above the heads of each disciple (men and women). Fire has purpose. It purifies, disintegrates, purges, transforms and liberates (frees) us from the past. This was the Holy Spirit (Ray 3, love and wisdom) being received by the disciples, so they would teach in the world and inform humanity of the Messiah (Christ), who initiated the new age (Pisces) and gave humanity the new law (adding to the 10 Commandments of the Aries Age) to Love (Ray 2) one another. Note: Gemini is also Ray 2. Shavuot is the Jewish Festival of Gladness, the First Fruits Festival celebrating the giving of the 10 Commandments to Moses as the Aries Age was initiated. Thus, we have two developmental stages here, Jewish festival of the Old Testament. Pentecost of the New Testament. We have gladness, integrating both.
