UC San Diego at RoboCup 2017



Darren Chen, a Ph.D. student in computer science at UC San Diego, had just landed in Japan when he saw ads in the subway for the competition he was going to take part in. "I realized it was a big deal," he said. He might even have panicked a little, he admitted.
In fact, the competition, called the RoboCup, brought more than 10,000 spectators and competitors to Nagoya, Japan at the end of July. The event, which is broadcast on Japanese TV, was celebrating its 20th anniversary. 
Chen was part of a team of Ph.D. students from the Contextual Robotics Institute here at the Jacobs School that was taking part in the event's RoboCup @ Home challenge. It was UC San Diego's first time taking part in the competition.
In the @ Home challenge, 10 universities from around the world compete to complete a series of tasks by programming and training a Toyota Human Support Robot. The UC San Diego team had to sort groceries and help a person carry grocery items.
 In addition, they faced a task to qualify. On the fly, they had to program the Toyota robot to autonomously navigate and map out a room without bumping into people and objects. The robot also had to be able to obey verbal commands in a noisy environment.
But the team's worst foe turned out to be the venue's WiFi. When 10,000 people were using the same radio band, it became difficult for the robot to communicate with other computers quickly.
The researchers enjoyed the experience of participating in the competition, and look forward to continuing to build assistive robots in the future.
In addition to Chen, the team working on the RoboCup @ Home challenge included   Angelique Taylor, Priyam Parashar  and Ruffin White as well master's student Jaskaran Virdi from the research groups of computer science professors Laurel Riek and Henrik Christensen. Christensen is the director of the Contextual Robotics Institute.

Smart Glove Turns Sign Language Into Text

video

Engineers at the University of California San Diego have developed a smart glove that wirelessly translates the American Sign Language alphabet into text and controls a virtual hand to mimic sign language gestures. The device, which engineers call “The Language of Glove,” was built for less than $100 using stretchable and printable electronics that are inexpensive, commercially available and easy to assemble.

The glove was created in the lab of nanoengineering professor Darren Lipomi. The lead graduate student on the project, Timothy O'Connor, spoke to 10 News - ABC San Diego about the work. Check out the video clip above.

In addition to decoding American Sign Language gestures, researchers are developing the glove to be used in a variety of other applications ranging from virtual and augmented reality to telesurgery, technical training and defense.

The glove also made an appearance in KPBS, Newsweek, Popular Mechanics, IEEE Spectrum and various other news outlets.

One Imaging Agent to Rule Them All

by Heather Buschman, UC San Diego Health


When you have a medical scan, it’s usually an MRI (magnetic resonance imaging), CT (computed tomography) or more recently, PL imaging (photoluminescence). Sometimes it’s all three as your care team works to determine what’s ailing you. That means three different appointments and three different imaging agents — typically nasty-tasting stuff you have to drink in order to sufficiently enhance the imaging signal so that diseased tissue can be distinguished from healthy tissue. Each comes with its own side effects and potential risks.
“What the medical field has long needed is a single imaging agent that will work across multiple imaging systems,” said Adah Almutairi, PhD, associate professor in the Skaggs School of Pharmacy and Pharmaceutical Sciences at UC San Diego.
Almutairi is always one to take up a challenge like that. Her bioresponsive materials lab is known for designing and developing smart polymers, nanoparticles and hydrogels for many innovative medical and research applications. One of Almutairi’s pet interests is in lanthanides, a family of naturally occurring chemicals that intrigued 19th century chemists because, among many other interesting properties, they burn easily in air, fluoresce under UV light and react with most nonmetals.
Inexplicably, scientific interest in lanthanides waned in the 1970s. A couple of years ago, Almutairi took up the mantle to explore how lanthanides do one special thing: convert low energy light into high energy light. She has long believed that her team could take advantage of that property for medical applications.
Almutairi and her team recently developed a new nanoparticle with a lanthanide-based core-shell-shell architecture. The nanoparticle emits light for optical imaging, but also relaxes water molecules for MRI and attenuates X-rays for CT simultaneously.

Three in one: the lanthanide nanoparticles can be used for photoluminescence (PL), computed tomography (CT) and magnetic resonance imaging (MRI) simultaneously.
In a study published in Nano Letters, the researchers tested these nanoparticles in “phantom” tissue — a hydrogel system that mimics living tissue in the laboratory. Not only does the nanoparticle work for each imaging type, it works better than each individual imaging agent on its own.
The team is now working to reduce the size of their new imaging nanoparticle so a patient’s kidneys can clear it more easily from the bloodstream.
“The main point of this study is that we overcame an engineering challenge,” said Sha He, a graduate student in the Jacobs School of Engineering at UC San Diego and first author of the new study. “Now we will tweak the design so we can advance this technology to pre-clinical and clinical testing. Our goal is that one day this nanoparticle, or one like it, will allow a patient to complete his or her imaging all at once, reducing the risk and toxicity associated with separate administration of multiple imaging agents.”

Mechanical engineering alumus honored for work on autonomous amphibious vehicle

UC San Diego Jacobs School of Engineering mechanical engineering alumnus Aaron Burmeister (B.S. mechanical engineering 2001) has been selected as one of the nation’s top scientists and engineers of the year by the Assistant Secretary of the Navy for Research Development and Acquisition.

Burmeister is an engineer for Space and Naval Warfare Systems Center Pacific (SSC Pacific). He won the prestigious Dr. Delores M. Etter Top Scientists and Engineers award, in the individual engineer category, for his work developing an autonomous amphibious vehicle.

“It’s challenging because perception, navigation, and control strategies have to change as the vehicle transitions from sea to surf zone to land domains. We have started the effort by developing an autonomy system that can control a commercially available amphibious manned vehicle capable of going up to 45 mph on land or water,” explained Burmeister, in a statement. 

He goes into more detail on the project in a US Navy video by Aaron Lebsack (embedded below).

Audrey Olsen
On June 14, the Center on Global Transformation (CGT) in partnership with the Institute for the Global Entrepreneur (IGE) hosted the UC San Diego Application Student Innovation Contest for undergraduate students at the Jacobs School of Engineering. Contest submissions were judged by industry experts, including Qualcomm executives and serial tech entrepreneurs. The winning product, by Audrey Olson, was called MatchRest.  It is a mutual accountability software application that matches people with comparable habits and sleep goals and rewarded them for staying and keeping one another on track. For example, a person with the sleep goals of falling asleep before midnight and turning off her computer an hour beforehand would check in with her partner nightly before doing each, and vice versa.  Each user would also have a virtual bedroom showcasing the status of his or her virtual avatar, which could be upgraded or customized more thoroughly as more goals were reached. Audrey won $5,000 in prize money. Second and third place students received $2,000 and $1,000 respectively.

Audrey’s partner in developing the product is Jesse Ren, acomputer science student and a 2016 NSF I-Corps participant. The Institute of Global Entrepreneur’s I-Corps program teaches lean start-up principles that are focused on product/market fit and customer discovery. Next up for the team, they plan on doing initial customer interviews in the fall to help in the development of their minimum viable product (MVP). They are currently working on personal projects (one such project is for UC San Diego's Project-in-a-Box initiative) while studying, applying, and interviewing for full-time post-graduate positions in the software industry.
We reached out to Elizabeth Lyons, Professor at the School of Global Policy, to talk about the contest.
IGE - What is the innovation contest and why hold it now?
EL - The UC San Diego Student Innovation Contest is a contest for undergraduates at the Jacobs School of Engineering (JSoE), who are interested in working on a real-world problem that has not yet been solved; second, expanding their knowledge and capabilities through a hands-on project; and third, the opportunity to win some money. We held the contest for the first time this year because of the important role innovation plays in economic growth and our interest in understanding whether it’s possible to encourage more innovation through contests like this. We also wanted to give JSoE students the opportunity to grow as innovators, and to build more links between the School of Global Policy and Strategy, JSoE, and the Institute for the Global Entrepreneur (IGE).

IGE -  What was it that made the winning team stand out?

EL - The winner of the contest did an outstanding job of building a commercially viable and technologically functional product. All the judges agreed that her application was user-friendly and that her revenue model was compelling. She stood out in how well she took into consideration all aspects of the innovative process. We received a number of submissions that were technologically very compelling or that had the potential to be commercially successful, but only a few that scored well in both areas.

IGE - When is the next challenge and how do teams sign up?

EL - We are currently working on how to proceed with the contest going forward. Our options for the next challenge will depend on the lessons we’re now compiling from the first contest. We’ve received very helpful feedback from many of our contest participants, and we’re also trying to analyze what led some participants to exert more effort than others in the hopes that we can improve on our contest design going forward. We will be sure to announce any upcoming challenges as soon as we’ve finalized the details!

UC Health Hack Expands Opportunities for Students, Builds Partnerships for the Future

By Jacquelyn Lim  

A few months after UC Health Hack 2017, organizers are still buzzing from the success of the hackaton's first partnerships with Southern California health institutions- UC San Diego Health, UC Irvine Heath and Rady's Children's Hospital- prompting event coordinators to start planning early for the annual event next year.

Health Hack was hosted in 2015 and 2016 solely by Engineering World Health (EWH)- the UCSD chapter of a nationally-backed organization dedicated to improving medical health and living standards in underdeveloped communities around the world.

This year was the biggest yet.

New partnerships with the three health systems doubled the amount of participants of what the event had previously.  It provided the opportunity for engineering and medical students to collaborate for the first time, to address the mission of EWH and current problems within partnered institutions.

The results were creative and innovative solutions to this year's most pressing topics: refugee healthcare, healthy aging, home care, and patient experience.

"We already had participation from UC Berkeley and are looking to partner with UCSF, UCLA and all of the other UCs next year," said Tracy Magee, Integrative Health Coordinator and Systems Information Project Manager.

Student prototypes thrilled event organizers, health experts and industry professionals.

"It's been a week and we are surprised, so impressed, we are deciding on where to go from here," Magee said.

Participants were divided into two tracks over two days to keep teams organized.  

One was the Integrative Health Systems Track, where teams developed solutions for domestic problems in clinical settings. The other was the Global Health Track, where teams developed solutions for international public health issues.

First, second and third place prizes were awarded to teams in both tracks after a panel of judges- experts in health and industry leaders- decided which prototypes stood out. Team members are awarded mentorship from the Von Liebig Entrepreneurism Center and are given lab space from the Pepper House, two incubators involved in the event.

Winning teams from the Integrative Health Systems Track will be able to apply their prototypes to in UC San Diego’s and UC Irvine’s health systems immediately, which is the next step in enhancing their projects.

“They will be able to incorporate items that are built into the UCSD and UCI health systems and will try real-world solutions to these problems already, that we see in our institutions; in Thornton and Jacobs Medical Centers,” said Magee.

Off the Wall, the team placing first in the Integrative Health Systems Track, created a project called "Incentivizing Patient Mobility Through Augmented Reality Art Therapy," which helps reduce delayed discharge and lack of mobility of inpatients using mobile technology to connect them to art. The pilot study was done at Jacobs Medical Center.

Global Health Track winning teams will also have the opportunity to further work on their prototypes.

“ Our goal is to ensure that the projects that are developed during UC Health Hack are pursued beyond the weekend,” said Niranjanaa Jeeva, EWH Health Hack Co-Director.

Awesome, the team placing first in the Global Health Track created a project called "Blueprints for Life: Design Solutions for Refugee Health," where international refugee communities lacking basic needs are connected to engineers through a website, to create blueprints for local infrastructure.  

In addition to having more participants, the hackathon drew larger sponsorships from leading companies.

“Amazon Web Service and Epic, were two proprietary software companies that got involved this year and we are wanting to expand the numbers of companies and incubators that get involved [next year],” said Magee.

EWH coordinators are identifying  goals they want to reach next year and plans have already taken shape. Jeeva says the event gained significant exposure this year and organizers are working on leveraging what was gained into the coming year.

" We want participants from all over California to come and attend. We will be aiming for over 500 participants!"
