Current Projects

Habitats Optimized for Missions of Exploration (HOME)

The scope of the HOME Space Technology Research Institute (STRI)’s research will be driven by two primary operational requirements of NASA’s deep-space habitats: (1) Keep humans alive while they are resident, and (2) Keep the vehicle alive while they are not. A highly autonomous deep-space habitat for human crews requires three major classes of control: autonomy, robotics, and humans – the interactions and interdependencies between these three domains comprise the research landscape for the HOME STRI. The goal of the STRI is to develop validated technology to help NASA ensure safe human habitability during crewed deep-space missions, and to maintain the habitat to support future crews even while uninhabited.The institute seeks to advance early-stage technologies related to autonomous systems, human and automation teaming, data science, machine learning, robotic maintenance, onboard manufacturing, and more. The HOME team is led by Stephen Robinson, principal investigator at UC Davis, in partnership with the University of Colorado Boulder, Carnegie Mellon University, the Georgia Institute of Technology, Howard University, Texas A&M University and the University of Southern California. Industry collaborators include Sierra Nevada Corporation, Blue Origin and Collins Aerospace Systems. Our lab will contribute to the development of early-stage technologies related to explainable AI as well as the understanding of trust in the context of human-autonomy integration.

Learning Based Formal Methods for Cognitive Aware Human-Multi-Robots Collaboration

In 1960, J.C.R. Licklider had a vision for a "Man-Computer Symbiosis" in which the human and computer/machine/robot, although dissimilar from one another, would live together in an intimate association. This may sounds like a scene from a science friction movie. But we may be not far away from this vision. In this project, we are going to partially realize this vision by studying how to enable a human to work alongside with a swarm of robot to perform very complex tasks, such as disaster relief missions. There are two features that are unique in the way we approach the problem. First of all, we take the human cognitive constraints, e.g., limited attention, into consideration. Second, we are able to provide a strong, robust guarantee that the human-robot team will behave as intended. This is crucial for robotics and AI as pointed out by Weld and Etzioni that "society will reject autonomous agents unless we have some credible means of making them safe".

This video shows one set of data we have collected from a human subject while he was remotely controlling a group of five robots in a triangular formulation to acquire a sequence of targets randomly projected on the groud. The video on the left was recorded by an overhead camera while the one on the right was recorded by a pair of gaze tracking glasses. The subject's EEG activities were also recorded (not shown here).

Smart Energy Management for Unmanned Aerial System Operation in Complex Military Missions

In recent years, unmanned aerial  systems (UAS) and other unmanned systems (UxS) have found their way onto the battleground to extend the reach of military forces, providing essential intelligence, surveillance and reconnaissance (ISR) as well as payload delivery and recovery. The increasing capability of such systems, particularly small and light-weight UxS swarms, has offered the Navy, the Marine Corps, and other military branches a significant opportunity to potentially reduce cost, increase system resiliency, and enhance operation effectiveness. However, one fundamental challenge impeding the wide deployment of small-scale UxS and UxS swarms is energy efficiency particularly in the context of complex military missions. Key performance indexes (KPI) of a mission, such as runtime, payload, and survivability, are often severely limited by the energy efficiency of the system. This project aims to tackle this challenge by investigating the fundamental physics governing the UAS energy performance and improving the mission KPIs through energy-oriented planning, control, and swarm collaboration.This is a collaborated work with Dr. Xinfan Lin. The project is funded by the NEPTUNE program of the Office of Naval Research (ONR).

Mitigating Ecological Destructive Events with a Network of UAVs

Our world is plagued with large-scale ecological disasters. Tragic examples include the Fukushima I Nuclear Power Plant calamity and the Deepwater Horizon oil spill. Today these disasters may be partially mitigated by teams of humans working in hazardous and labor intensive environments. To combat these destructive environmental processes, this project instead envisions the development of a network of UAVs that can combat these disasters, while keeping humans at a safe distance. We will use precision agriculture as a test bed to develop a multi-UAV system that will 1) use cameras mounted on UAVs to map out distribution of pest-infested plants in a heterogeneous grid pattern of crop plants with/without pest infestations, 2) transfer the map from the imaging UAV to a ground station (or a fixed wing aircraft) to compute an optimal mitigation solution, and 3) deploy actuating UAVs to implement the solution (release of natural enemies to the pest population on crops) to the plants with symptoms of pest infestation.

This is a collaborated work with Christian Nansen from the Department of Entomology and Nematology, UC Davis. The project is partially funded by the Western SARE: Sustainable Agriculture Research and Education and the California Department of Pesticide Regulation. Our project has been featured by two local news stations: ABC10 and CBS13, as well as ASME.

The video shows experimental dispersion of vermiculite mixed with predatory mites. We are in the process of developing algorithms and control systems of the dispensing device so that we can precision-target the release of natural enemies by taking into account drone altitude and speed and account for wind speed and wind direction.

Exploring the Possibility of Using UAS with Low-Cost Sensors for Air Quality Monitoring

The goal of the project is to explore the possibility of using unmanned aerial systems with low-cost sensors to measure and subsequently study air quality. We have successfully conducted out first test (see video below) using a DJI S1000 Octocopter equipped with a low-cost air sensor package (BME280 and PMS7003) to measure the early-morning vertical stratification of the atmosphere at the Russell Sports Field of the UC Davis. Working closely with researchers from the UC Davis Air Quality Research Center, we are currently working on updating our UAS, including both its hardware and software, as well as the sensor package to accelerate forest management and support firefighting and post-fire rehabilitation in forests and rangelands.

Augmented Reality Multi-Player Quadcopter Game System

Recently years we have a rapid development of virtual reality and augmented reality based games. One of the missing pieces has been whether it is possible to combine them with the physical world. The goal of the project is to develop an augmented reality multi-player quadcopter computer game system capable of adding computer generated elements to videos transmitted from cameras on the quadcopters, and presenting the combined images on virtual reality goggles. The computer will take control of the quadcopters if necessary to avoid collisions with other quadcopters, game elements, or the playing field boundaries and to add game physics.

This project is a collaboration with Dr. Nelson Max from the Computer Science Department of UC Davis. The project is partially funded by the UC Davis Office of Research through a Science Translation and Innovative Research (STAIR) grant.

Data-Driven Personalized Training of Next-Generation Workforce

Humans, in the role of either customers, designers, program managers, or workers, will always play a significant role in future manufacturing. However, the systems that the humans are interacting with are becoming increasingly complicated especially with the rise of large-scale industrial cyber-physical systems (CPSs), also called Industrial Internet of Things (IIoT). This project is aimed at developing a data-driven method of modeling and analyzing manual expertise of humans while they are interacting with CPSs as well as traditional machines. The insights we are going to gain from this project can not only help us to build machines and CPSs that can collaborate with humans more efficiently and effectively but also help us to facilitate the knowledge transfer among generations. This is a collaborated work with Barbara Linke from the Department of Mechanical and Aerospace Engineering, UC Davis.
