Mechanical engineer recognized by Society for Industrial and Applied Mathematics

Jorge Cortes, a professor in the Department of Mechanical and Aerospace Engineering has been inducted as a 2020 Fellow by the Society for Industrial and Applied Mechanics.
Cortes is being recognized for contributions to the control and optimization of network systems.

The fellows were nominated for their exemplary research as well as outstanding service to the community. Through their contributions, SIAM Fellows help advance the fields of applied mathematics and computational science.

Cortés' research interests are on distributed coordination algorithms, autonomous robotic networks, adversarial networked systems, mathematical control theory, geometric mechanics and geometric integration. The recent emergence of low-cost, highly-autonomous vehicles with control, communication, sensing, and computing capabilities has paved the way for the deployment of robotic sensor networks in a wide range of applications. Controlled motion coordination of these networks will have far-reaching implications in the monitoring of natural phenomena and the enhancement of human capabilities in hazardous and unknown environments. Motivated by these scenarios, Professor Cortes' research program is developing systematic methodologies to control autonomous, reliable, and adaptive mobile networks capable of operating in unknown and dynamic environments.

What happens when two roboticists, one engineer and one holographic doctor are together on a panel?

Actor Robert Picardo, who played The Doctor in Star Trek Voyager. 
We found out Saturday, when when three of our professors were on the same panel at the holographic doctor from Star Trek Voyager, aka actor Robert Picardo. They discussed the future of healthcare robotics and AI. It was all that of "The Future of Medicine," an event hosted by the Clarke Center for Human Imagination, June 2 here on campus. Below is a Twitter thread with some of the event's highlights.

It's about empowering people; it's not about replacing people: The future of robotics


"It's about empowering people. It's not about replacing people."
That's the message that Henrik Christensen, director of the Contextual Robotics Institute at UC San Diego, has been trying to spread about robotics and automation.
He spoke to Per Sjöborg from Robohub in an extensive interview.

Some highlights and predictions from the video:

"Robots are going to be pervasive in our lives going forward." That means researchers will need to figure out how to make it easy for everyone to interact with robots. "I want people who have never used a computer to be able to use this technology."

"One day we'll have robotic beds that will make sure you get adequate sleep."

"By the time I retire, I will have a self-driving car."

"We might have food that has never been touched by humans [only by robots]."

Video: Jacobs School computer scientist talks about the future of health care robotics

 UC San Diego computer scientist Laurel Riek wants to put a robot in someone's home for six months.
"We want to build robots that can adapt to learn from and change with a person, not only throughout the week, but throughout the day," she says in this video for the journal Communications of the ACM.
Riek is the author of a review article titled Healthcare Robotics in the journal's November 2017 issue.
The full text of the article is available here: https://cacm.acm.org/magazines/2017/11/222171-healthcare-robotics/fulltext
She is a professor of computer science at the Jacobs School of Engineering at UC San Diego and a faculty member of the campus' Contextual Robotics Institute.
Her research goal is to enable robots to robustly solve problems in dynamically- changing human environments. Riek is particularly focused on problems in real-world, safety-critical healthcare environments, such as hospitals, homes and clinics. Her work tackles the fundamental and applied problems that make complex, real-world perception and interaction in these spaces so challenging for robots. Riek’s work draws on techniques from the fields of computer vision, machine learning, non-linear dynamics, and human factors to enable robots to autonomously perceive, respond, and adapt to people in the real world.

Combining soft robotics and space technology

Paul Glick, a Ph.D. student at the Jacobs School, got a unique chance to do hands-on at the Jet Propulsion Laboratory in Pasadena, Calif.
Glick, who works in the lab of mechanical engineering professor and roboticist Michael Tolley, got to design and carry out most of the experiments for an electrostatic gripper for flexible objects build by JPL and UC Berkeley engineers. The team presented their work at the IROS 2017 conference in late September in Vancouver.
Glick is part of the NASA Space Technology Research Fellowship program. He works to bring soft robotics to space technology. Here is a more detailed description of his research. 
Tolley's group will present some of their research at the Oct. 27 Contextual Robotics Forum here on the UC San Diego campus. 
Watch a video of the gripper that Glick ran experiments on in action:

Shared Autonomy


A blog post by Henrik Christensen, Director, UC San Diego Contextual Robotics Institute. (The post originally appeared on Christensen's blog. Follow Christensen on Twitter: https://twitter.com/hiskov)

We are at present seeing a lot of interest in autonomous systems. A lot of automotive companies are talking about autonomous cars or driver-less cars. GM and Google demonstrated early systems. Google started out with automation of regular cars and has also presented a concept system for a car without a steering wheel [URL]. Tesla has a model where the driver is expected to take over [URL] when the autopilot cannot provide a robust solution. The sharing of autonomy between well understood contexts – that are handled automatically and human intervention for challenge situation is a version of shared autonomy, where humans and robots collaborate to achieve a mission objective.
Tele-operation of robots has existed for a long-time. Much of the early work was carried out in the  handling of radioactive material, where direct contact by people is not an option. These systems were all purely tele-operated. This is the same type of model we see applied to medical robots such as minimally invasive systems. The Intuitive Surgical System – Da Vinci [URL] is a great example of such a system. The objective is here minimization of trauma to the body.
For Aerospace Systems we have long known the auto-pilot which is a shared autonomy system. The pilots will typically handle take-off and landing, whereas cruise flight is handled by the auto-pilot. For Unmanned Aerial Vehicles (UAVs) the pilots / operators are sitting on the ground and operating vehicles that may be airborne for as long as 36 hours. We are seeing similar applications for smaller UAVs for commercial and entertainment tasks. New commercial applications include building inspection and mapping of construction sites [URL]. For entertainment companies such as DJI [URL] build robots that are radio controlled. We are slowly seeing small functions such as level keeping or automation tracking of skiers which are examples of shared autonomy. The systems are launched and an objective is specified (tracker me, or maintain level) which is performed autonomously.
One of the biggest challenges in design systems with shared autonomy is to provide the operator with adequate context to allow them to take over as appropriate. A great example of a system that does this in an industrial context is the company Aethon [URL] out of Pittsburgh. They provide delivery robots for hospitals and other institutions. The objective is an autonomous system, but when a robot gets caught in an unusual situation such as a trashcan in the middle of a hallway, the robot requests assistance from a call center. The operator uses the on-board sensors to understand the problem and drive the robot out of the situation. If you are in a car taking over control is more of a challenge when you are driving 55 mph down the highway. It takes time to understand the challenge and to take over, which challenges the design of such systems with automatic takeover. How do we provide the driver with adequate information to take over control of the car? Or is this an appropriate model for shared control?
As we explore the shared control of systems with some functions performed autonomously and others carried out by an operator it is essential to consider the fluency of human-robot interaction, to consider the cognitive aspects of systems and to ensure that engineers use these models as an integral part of their systems design. On October 28, 2016, the University of California San Diego will host the annual Contextual Robotics Forum with the theme of “Shared Autonomy: New Directions in Human-Machine Interaction”. Join us for a day focused on the future of robotics and shared autonomy. You'll meet world-leaders in robotics and connect with the robotics ecosystem at UC San Diego and in the region at the technology showcase.

Over the next few years we will see tremendous progress on design of systems that off-load the operator but we will be challenged in doing this in a way that still allows the operator to intervene for challenge cases. So far few systems have managed to do this with a high degree of fluency. We need more research at the intersection of cognitive science, system engineering and robotics to fully leverage next generation systems with shared autonomy.

UC San Diego Robotics organization to compete in new season of BattleBots


We sat down with the founders of Triton Competitive Robotics (TCR), mechanical engineering major Jeffrey Wang and Mahaela Johnson to discuss their student organization.

Q: Tell us about your organization in your own words:
M: Triton Competitive Robotics provides resources to students interested in building robots to enter into competitions. Students can pitch their idea for a competition to enter and then TCR will put together a team of students to work on a robot for the competition as well as provide workshops and funding.
J: Our mission really is to build and strengthen the robotics community here by making sure there’s nothing stopping someone that wants to pursue a robotics project. We’re working hard to make sure everyone has access to resources that will help them - and one way to do this is by collaborating with other organizations. For example, samcad, a student org that focuses on 3D modeling, just put on a very successful SOLIDWORKS workshop for us.

Q: Why did you decide to start this organization?
J: I remember attending an orientation freshman year and talking with someone about the lack of robotics student orgs on campus. I’ve since discovered them (IEEE does great work, for example,) but none of them really focused on the projects I wanted to pursue. Our goal is to fill that gap.
M: I was at home watching BattleBots and I thought, UCSD has an amazing engineering program and we’re more than capable of creating our own Battlebot; we should do this. Since then, the scope of our organization's interests has expanded to all robotics competitions.

Q: What projects is your organization working on right now?
M: We currently have two projects. One is a 3 lb autonomous fighting robot that we plan on entering into next year’s Robogames competition. Our other project is our BattleBots team which is being led by Jeffrey.

Q: How can interested students get involved?
J: All of our project meetings are open to the public (you can find the times/locations on Facebook or by emailing us.) Currently, all positions are filled for the two projects but as we start building we would potentially need more team members. Keep in mind that if you and some friends have a different competition you’re passionate about, we can help you compete!

Q: Contact info?
M: Find us on Facebook! https://www.facebook.com/groups/tritonrobots/ or email either of us at mkj002@ucsd.edu and jewang@ucsd.edu
