ECE Seminar Co-hosted by CPSRC: Tightly Integrated Design and Control of Aerial Robots
Aerial robots are present in a variety of domains. In this talk I will discuss some approaches to expanding their capabilities through novel design; specifically viewing the design through the lens of the control problem. I will discuss vehicle designs that achieve greater disturbance rejection through angular momentum, that can morph mid-flight to traverse obstacles, and that can survive and exploit collisions with the environment. Two design approaches to (partially) overcoming the inherent energy storage constraints for aerial vehicles will also be discussed, motivated by challenges in creating useful urban air mobility vehicles ("air taxis"). Time permitting I will also share some work on motion planning for rapid flight through unstructured environments.

ECE Seminar Co-hosted by CPSRC: Vision-Based Tracking with Small UAVs
This talk will describe our current work on vision based autonomous target tracking and following using small UAVs. We will present a new multiple target tracking algorithm that is based on the random sample consensus (RANSAC) algorithm that is widely used in computer vision. A recursive version of the RANSAC algorithm will be discussed, and its extension to tracking multiple dynamic objects will be explained. The performance of R-RANSAC will be compared to state of the art target tracking algorithms in the context of problems that are relevant to UAV applications. We will also discuss recent research on vision based relative pose estimation. We will describe a technique for using point correspondences in video to estimate the camera pose, where the cost function to be optimized is derived from the epipolar constraint.

Artificial Pancreas Project in Argentina
In this talk a brief introduction to diabetes and the glucose control through an artificial pancreas will be presented. The complete solution, from the computation of a control-oriented model, it’s (in)validation vs. experimental data, the design of a controller and its test through simulations and clinical trials will be described. The first three clinical trials in Latin America and some ongoing and future research are also presented.

The IoT Will Change Everything
Wirelessly-enabled sensing technologies offer the hope of enabling economically and socially important applications including intelligent transportation systems and other so-called smart city initiatives, home automation, improvements in manufacturing, and tools for humanitarian assistance and disaster response. Importantly, the value may only be realizable through the integration of a number of dis-similar, separately-built, separately-owned, and separately-controlled sensing sub-systems. Our research at CMU over the last five years has aimed to create, deploy and validate a framework that addresses key challenges that arise in such a system-of-systems.
In this talk, we present some outcomes from this project. We begin with an examination of practical barriers in a typical IoT application. From this, we develop themes related to low-power operation, programmability, synchronization, federation, and the interplay between them. Within this context, we discuss (1) a new language framework, called TTPython, that seeks to ease the programmer's burden in creating software for such complex, heterogeneous, distributed, fault-prone systems, (2) an overlay architecture for IoT devices that makes them a suitable compilation target for TTPython, (3) compilation and mapping concepts, and (4) a systems demonstration.

ECE Seminar Co-hosted by CPSRC: Towards Scalable and AI-Enabled Autonomous Systems
Current autonomous systems, comprising of intelligent machines, devices, and software that are aware of and interact with their environment, have the potential to accomplish a previously intractable scope of tasks. Their ever growing capabilities are already enabling them operate in the real- world, making independent decisions and even learning in uncertain, unstructured, and unpredictable environments. These new systems will soon be able to replace humans in hazardous environments and tedious jobs, provide them with up-to-the-minute situational awareness, assist them in difficult or repetitive tasks, and enhance their capabilities. For autonomous systems to show their full potential, new methods are necessary that will allow them to seamlessly infer, reason, and act in the real-world using large amounts of data, learn from their experiences and improve their performance, accept naturally expressed instruction from humans, adapt and respond to unpredictable situations, and effectively interact with each other and humans to accomplish collaborative tasks.
