In this paper, we outline a low cost multi-robot autonomous platform for a broad set of applications including water quality monitoring, flood disaster miti-gation and depth buoy verification. By working cooperatively, fleets of vessels can cover large areas that would otherwise be impractical, time consuming and prohibitively expensive to traverse by a(More)
Low-cost localization solutions for indoor environments have a variety of real-world applications ranging from emergency evacuation to mobility aids for people with disabilities. In this paper, we introduce a methodology for indoor localization using a commercial smart-phone combining dead reckoning and Wifi signal strength fingerprinting. Additionally, we(More)
— This paper presents the design and results of autonomous behaviors for tightly-coupled cooperation in heterogeneous robot teams, specifically for the task of navigation assistance. These cooperative behaviors enable capable, sensor-rich (" leader ") robots to assist in the navigation of sensor-limited (" simple ") robots that have no onboard capabilities(More)
— This paper presents an approach for deploying a team of mobile sensor nodes to form a sensor network in indoor environments. The challenge in this work is that the mobile sensor nodes have no ability for localization or obstacle avoidance. Thus, our approach entails the use of more capable " helper " robots that " herd " the mobile sensor nodes into their(More)
The vision of humans and robots working together as peers to accomplish complex tasks has motivated many recent research endeavors with a variety of applications ranging from lunar construction to soccer. However, much of this research is still at an early stage, and many challenges still remain in realizing this vision. A key requirement for enabling(More)
— This paper presents an adaptive causal model method (adaptive CMM) for fault diagnosis and recovery in complex multi-robot teams. We claim that a causal model approach is effective for anticipating and recovering from many types of robot team errors, presenting extensive experimental results to support this claim. To our knowledge, these results show the(More)
Multi-robot systems (MRS) have great promise for revolutionizing the way a variety of important and complex tasks are performed. While the underlying science is advancing quickly, the engineering problems associated with deploying multi-robot team under real world constraints have not been adequately addressed. In this work, we are developing teams of(More)
— The failure-prone complex operating environment of a standard multi-robot application dictates some amount of fault-tolerance to be incorporated into the system. Being able to identify the extent of fault-tolerance in a system would be a useful analysis tool for the designer. Unfortunately, it is difficult to quantify system fault-tolerance on its own. A(More)
