Artificial Pancreas Project in Argentina
Abstract
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
Abstract
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
Abstract
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.

The Barycenter Method for Direct Optimization: an Overview with Applications
Abstract
We will present properties of the recently developed barycenter method for direct optimization that make it particularly useful in control applications. Equivalence of the method's batch and recursive formulations can be used to show that it has descent-like properties, although no derivatives are used, and that it is robust to noisy measurements and lack of differentiability. As a relevant application example, the method can be employed in the joint estimation of parameters and switching times for hybrid linear systems, an important problem that can pose significant computational challenges due to the non-convex nature of the combined optimization.

RAPID: Robot Assisted Precision Irrigation Delivery
Abstract
Agricultural irrigation consumes 70% of the world's freshwater. Emerging sensing technologies such as UAVs equipped with heterogeneous sensors can provide farmers with detailed maps of water use and ground conditions, but closing the sensing-actuation loop to adjust irrigation at the plant level remains an unsolved challenge. Some proposed solutions rely on networks of motorized wireless actuators that are costly and prone to failure in field conditions. RAPID (Robot-Assisted Precision Irrigation Delivery) explores an alternative approach whereby humans and robots collaborate to adjust low-cost, adjustable drip irrigation emitters at the plant level. RAPID is designed for cost-conscious farm managers to be retrofit to existing irrigation systems and incrementally expanded to increase irrigation precision, reduce water usage, and permit thousands of emitters to be incrementally adjusted. The project involves the design, development, and evaluation in the field of robust co-robotic systems compatible with existing drip irrigation infrastructure in vineyards and orchards. After giving an overview of the project, in this talk I will illustrate a set of results in the area of routing in vineyards for single and multiple robots.
