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.

Alum demos 3D avatar from just one 2D picture

Watch Jacobs School alum Iman Sadeghi demonstrating how you can build a 3D avatar from just one 2D picture by using software from Pinscreen, the company where Sadeghi is VP of engineering.
The technology is powered by neural networks and GPUs.
The Pinscreen demo starts around the 50:30 mark.
The 3D avatar can be used in VR environments. It is expressive and reflects different light conditions.
