Abstract

The goal of my lab's research is to move us towards a world where everyone, everywhere can have and use robots. Towards that end, we study accessible custom creation of electromechanical solutions; this paradigm begets individual devices with significant resource constraints and lower individual capabilities. We need to then also come up with new control strategies that can achieve high level behaviors despite this resulting low fidelity hardware. In particular, we co-design across subsystem boundaries--particularly sensing, communications, and mobility--to optimize overall task performance. We can explore this paradigm particularly as it relates to multi-robot systems. With the careful use of networking capabilities, resources and results can be effectively shared among agents to achieve greater system-wide performance. For example, most systems of mobile robots need to compute some shared state estimate (such as swarm localization); we investigate new algorithms for joint sensing and communication planning. When considering other sensing or coverage tasks, we develop motion planning algorithms around communications constraints. We explore new representations of state to address more fundamental questions in multi-robot analysis. Our work on these topics will come together with our other research on design and fabrication to allow accessible and low-cost functional robots for everyone.
