CU-Boulder team develops swarm of pingpong ball-sized robots
Dec 14th
Correll and his computer science research team, including research associate Dustin Reishus and professional research assistant Nick Farrow, have developed a basic robotic building block, which he hopes to reproduce in large quantities to develop increasingly complex systems.
Recently the team created a swarm of 20 robots, each the size of a pingpong ball, which they call “droplets.” When the droplets swarm together, Correll said, they form a “liquid that thinks.”
To accelerate the pace of innovation, he has created a lab where students can explore and develop new applications of robotics with basic, inexpensive tools.
Similar to the fictional “nanomorphs” depicted in the “Terminator” films, large swarms of intelligent robotic devices could be used for a range of tasks. Swarms of robots could be unleashed to contain an oil spill or to self-assemble into a piece of hardware after being launched separately into space, Correll said.
Correll plans to use the droplets to demonstrate self-assembly and swarm-intelligent behaviors such as pattern recognition, sensor-based motion and adaptive shape change. These behaviors could then be transferred to large swarms for water- or air-based tasks.
Correll hopes to create a design methodology for aggregating the droplets into more complex behaviors such as assembling parts of a large space telescope or an aircraft.
In the fall, Correll received the National Science Foundation’s Faculty Early Career Development award known as “CAREER.” In addition, he has received support from NSF’s Early Concept Grants for Exploratory Research program, as well as NASA and the U.S. Air Force.
He also is continuing work on robotic garden technology he developed at the Massachusetts Institute of Technology in 2009. Correll has been working with Joseph Tanner in CU-Boulder’s aerospace engineering sciences department to further develop the technology, involving autonomous sensors and robots that can tend gardens, in conjunction with a model of a long-term space habitat being built by students.
Correll says there is virtually no limit to what might be created through distributed intelligence systems.
“Every living organism is made from a swarm of collaborating cells,” he said. “Perhaps some day, our swarms will colonize space where they will assemble habitats and lush gardens for future space explorers.”

CU : Some good news for doggie lovers
Dec 11th
clinical study to treat canine pain
A University of Colorado Boulder professor and her biomedical spinoff company Xalud Therapeutics Inc. of San Francisco are teaming up with a Front Range veterinarian to conduct a clinical study targeting an effective treatment for dogs suffering from chronic pain.
Distinguished Professor Linda Watkins of CU-Boulder’s psychology and neuroscience department said the study involves treating ailing dogs with a gene therapy using Interleukin-10, or IL-10, a protein and anti-inflammatory that both dogs and humans produce naturally. Watkins is working with veterinarian Robert Landry of Mountain Ridge Animal Hospital and Pain Management Center in Lafayette, who will be treating canine patients suffering from chronic and painful conditions, some of which already are being treated with various other medications with limited success.
Animals perceive and experience several levels of pain that are similar to humans, and chronic pain can be debilitating and also shorten the lives of pets, said Landry, one of only a handful of credentialed American Academy of Pain Management practitioners in Colorado. Landry currently is seeking Denver-Boulder area pet owners who have dogs suffering from chronic pain and who might be interested in participating in the study, which is free.
The new study is driven by research spearheaded by Watkins indicating a type of cell known as glial cells found in the nervous system of mammals plays a key role in pain. Under normal conditions, glial cells act as central nervous system “housekeepers,” cleaning up cellular debris and providing support for neurons, said Watkins. But glial cells also can play a pivotal role in pain enhancement by exciting neurons that both transmit pain signals and release a host of chemical compounds that cause problems like chronic neuropathic pain and other medical issues.
The team will use Xalud’s lead product candidate, XT-101, a gene therapy that harnesses the power of the potent anti-inflammatory IL-10 to normalize glial activity and eliminate neuropathic pain for up to 90 days with a single injection.
The gene therapy based on IL-10 has a number of advantages, including suppressing glial activity in the spinal cord, stimulating tissue regeneration and growth, decreasing the production of pro-inflammatory substances and increasing the production of anti-inflammatory substances, Watkins said. Landry and Watkins also have been working with the American Kennel Club on potential funding for additional clinical studies involving the treatment of chronic pain in dogs, said Watkins.
“We have already tested this new therapy in two pet dogs, and both have had remarkable reversals of their pain for long durations after a single injection of the therapeutic,” she said. “Our early peek at the potential of this therapeutic treatment in dogs shows essentially the same positive effects we have seen in laboratory rats used in our studies that have been treated with the therapy.”
Watkins said demonstrating the efficacy and safety of the new gene therapy in a second species of mammal is important in terms of moving it forward to eventually meet FDA regulations for human clinical trials.
In addition to studying what triggers glial cells to become activated and begin releasing pain-enhancing substances and ways to control chronic pain, Watkins and her research team recently discovered that clinically prescribed opioids also activate glial cells and cause them to release pain-enhancing substances. “Our ultimate goal is to find a means by which clinical pain control can be improved so as to relieve human suffering,” she said.
To contact Landry about possible participation in the study by family dogs suffering chronic pain and that might benefit from the experimental treatment, call the Mountain Ridge Animal Hospital at 303-665-4852.

CU-Boulder to honor vets through Veterans Week events Nov. 9-17
Nov 9th
The free, public ceremony will feature guest speaker Michael Dakduk, executive director of the national organization Student Veterans of America. A reception will follow in the UMC Veterans Lounge.
In the Marine Corps, Dakduk was deployed to Iraq in 2005 and to Afghanistan in 2007, where he earned military decorations for distinguished service in combat. He left active duty in 2008 and completed his bachelor’s degree at the University of Nevada Las Vegas, where he organized student veterans on campus as a chapter of Student Veterans of America.
“We take this time to acknowledge and express gratitude for the sacrifices of those still serving and those who have served so gallantly and selflessly in our armed forces,” said CU-Boulder Chancellor Philip P. DiStefano. “This weekend, we can each take a moment to reflect on how much we owe the silent heroes in our midst and reach out and thank a vet for this outstanding service. The University of Colorado Boulder joins the nation on this one day of the year our country has set aside to honor our veterans and acknowledge the legacy of their steadfast defense of our American ideals, principles and liberties.”
Also on Nov. 9, CU-Boulder will host Military Student Day to assist military service members interested in transitioning from military service to life as a college student.
CU-Boulder is home to about 650 student veterans and 250 faculty and staff vets, according to Michael Roberts, program manager of CU-Boulder’s Veteran Services office on campus.
“The Office of Veteran Services here at CU-Boulder continues to build a robust program supporting our veterans transitioning from the military to college and ultimately to the work force,” Roberts said. “We have a group of committed staff and faculty leaders who are eager to support our student veterans.”
Student veterans can visit the Student Veterans Center in the Center for Community building, room S482. The center serves as a one-stop shop to support student veterans.
One of the most sought-after services is help with the GI Bill, Roberts said.
“Most veterans are taking advantage of this great opportunity they earned while serving our nation,” he said. “The Post 9/11 GI Bill covers all in-state tuition and fees as well as providing a monthly living allowance. In Boulder, it is quite substantial — $1,500 per month while they are in school.”
The CU-Boulder Law School also recently opened the Veteran’s Legal Clinic to help unite the Colorado legal community and students at CU as they work together to develop a support system for veterans across the state.
Mark Fogg, president of the Colorado Bar Association and a Colorado Law alumnus, recognized the need for pro bono legal services in the veteran’s community in Colorado, said Andy Hartman, an adjunct professor and director of the experiential learning program at Colorado Law.
“The bar wanted to have veteran’s clinics in different cities throughout Colorado including Denver, Fort Collins, Colorado Springs, Pueblo and Grand Junction, and they wanted a program at CU-Boulder and the University of Denver to serve their student veterans and their families,” Hartman said.
Attorneys from the Colorado Bar Association work with student volunteers from Colorado Law to meet with veterans and address some of their legal questions. Neither party is financially compensated for their work, although it affords practicing attorneys and students the opportunity to fulfill their public service pledge to provide legal services that benefit the community.
Kevin Brown, a third-year law student at CU-Boulder and a former attack pilot for the Marines, has a vivid memory of the Veterans Legal Clinic’s first client.
“The very first person that walked into the clinic last November on Veterans Day was a homeless veteran that needed many different kinds of help,” said Brown. “To see a veteran who was homeless and in need and to watch the Colorado Bar Association and the volunteer attorneys come together and work to provide assistance and help to him was inspiring.”
Other campus observances for Veterans Day include:
Nov. 9, at 6 p.m., in Old Main Chapel
The CU-Boulder Veteran Services office will have a public viewing of the documentary “Veterans Day 11.11.11.” The feature-length documentary examines what it means to be a veteran in America through the stories of several men and women vets who served during times of peace and war.
Pat Woodard, the documentary’s co-executive producer and writer; Richard Deki, one of the veterans featured in the documentary; and Suzanne Popovich Chandler, a photographer whose work is featured in the documentary, will be present to interact with the audience during and after the film.
Nov. 14, 6-9 p.m., Old Main Chapel
A public showing of the documentary “The Welcome,” an award-winning film that offers a “fiercely intimate view of life after war: the fear, anger and isolation of post-traumatic stress that affects vets and family members alike.”
Nov. 17, 9 a.m., UMC Glenn Miller Ballroom
The annual veterans pre-game party honors CU’s military families as well as members of the military across the Front Range community. For more information contact the Veteran Services office at 303-492-7322.
