Digital production strategies for novel electronic devices

Abstract
The production and consumption of electrical and electronic equipment (EEE) in the European Union (EU) are on the rise (Eurostat 2020). Due to low levels of reuse, collection, recycling, and other forms of recovery of waste EEE, the consumption of rare and expensive natural resources is also increasing. This imposes higher economic and environmental pressure on manufacturers of modern electronic devices. As new fields of applications for novel, soft, non-planar electronic devices continue to emerge, such as wearable smart textiles, medical/health-monitoring devices and miniature autonomous robots, the market for these electronic devices is expected to grow rapidly. Amid the COVID-19 crisis, research indicates that the global stretchable electronics market will reach $2.6 billion by 2027 (Researchandmarkets 2020). The development of methods to assess the ecological impact of not only the electronic device, but also the production process, is an area of research that is growing. Life Cycle Assessment (LCA) is a useful method to identify and quantify the environmental impacts of a product, process, or activity. Comparative LCA can be carried to compare the environmental impacts of two or more products that have similar functionality. The production process for stretchable electronics that is being developed in the SOMIRO project is based on a digital production strategy, where the production steps are digitally controlled and optimised.

Soft Electrostatic Actuators for Small-Scale Machines/ Electrostatics in Action

Abstract
Muscle-mimetic actuators are about to transform robotic systems by enabling ever more life-like creations. This transformation flourishes by the development of functional materials that are soft or soft-hard hybrids, paving the way for energy-efficient autonomous machines. Yet, achieving the power and energy density found in natural muscles remains a major scientific and engineering challenge in artificial systems. Actuators based on electrostatic driving mechanisms are a powerful approach to this problem due to their high energy density, fast contraction, and ease of fabrication. This talk highlights promising actuator designs for small-scale machines in the millimeter to centimeter scale. With a focus on strategies to downscale actuators, we provide materials solutions, fabrication strategies, and discuss various applications from tunable optical systems to swimming robots. In addition to this presentation, we will do a practical activity to show electrostatics in action.

Learn more about rice

Abstract
To improve production and competitiveness in the field it is necessary to increase knowledge of the crop in place in order to adopt the best strategies and choices. Especially in the production of organic rice, having an instrument that provides information on the elements present in the water is certainly useful for cross-referencing the satellite maps of vegetative vigor. The objective will be to use the millirobots in a rice paddy with different experimental varieties of rice, submerged with about 15/20 cm of water. We are going to define small areas in which to contain the movement of the millirobot and manage the communication of information. The prospect is to use it in the future in more fields and during the different stages of rice growth. It is a technology that does not exist today as the information is received through vegetative vigor sensors, satellite maps, yield production maps; it will be a great opportunity for rice producing companies.

Robotic Monitoring of Habitats: the Natural Intelligence Approach

Abstract
Global warming and pollution are threatening the survival of over one million species in nature. Continuous monitoring of habitats is paramount to protecting and preserveing this biodiversity. Robotics can solve this issue and enhance environmental conservation through the active assistance of humans. However, the technical barriers that still need to be tackled are numerous. We propose a framework to perform terrestrial habitat monitoring exploiting the mobility of legged robotic systems. The robot will be provided with the Natural Intelligence introduced as the combination of the environment in which it moves, the intelligence embedded in the design of its body, and the algorithms composing its mind. This approach could solve the challenges of deploying robots in real natural environments, such as irregular and rough terrains, long-lasting operations, and unexpected collisions, with the final objective of assisting humans in assessing the habitat conservation status. Finally, we present examples of robotic monitoring of habitats in three different environments: forests, grasslands, and dunes.

The MAPWORMS project: Biomimicry, smart materials and shape-morphing robots

Abstract
The talk describes the unique approach and the first results obtained in the framework of the MAPWORMS project, which aims at starting a novel paradigm of robotics and overcoming the limitations of current state-of-the-art solutions by embedding responsivity in the constitutive materials of the machines. The objective is developing a new concept of bioinspired robots operating in response to environmental stimuli thanks to their shape-morphing configuration. The result is a completely autonomous robot capable of performing many different tasks, rather than a robot controlled by a central unit and able to execute specific tasks only in a pre-defined and structured environment. The shape morphing behaviour is inspired by the marine Annelida, which are able to adapt to all the marine habitats, even the extreme ones, by burrowing into sediments, anchoring to holes and crevices, exploring the surroundings by protruding and elongating body parts, and retracting the body to escape predation.

Swarm robotics: leveraging bio-inspiration for collaborative robots

Abstract
Swarm robotics studies the design and implementation of multi-robot systems with decentralised control capable of tackling complex missions thanks to self-organisation and collaboration. The basic idea of swarm robotics is to use robots capable of relatively simple behaviours, and therefore with low production costs, exploiting the collaboration between robots to perform complex tasks as a group. A clear example of how this is possible comes from biology, and in particular from the observation and study of the behaviour of eusocial animals such as bees or ants. In this seminar, I will show how complex behaviours at the group level (e.g., aggregation, coordinated motion and group decisions) can be obtained thanks to very simple individual rules, derived from the observation of natural systems.

Materials and methods for sustainable soft system – from biodegradable tough gels to mycelium based electronic skins 

Abstract
Modern societies rely on a multitude of electronic and robotic systems, with emerging stretchable and soft devices enabling ever closer human machine interactions. These advances however take their toll on our ecosystem. Mitigating some of these adverse effects, this talk introduces materials and methods for soft systems that biodegrade. Based on highly stretchable biogels and degradable elastomers, our forms of soft electronics and robots are designed for prolonged operation in ambient conditions without fatigue, but fully degrade after use through biological triggers. Going beyond, we introduce a systematically-determined compatible materials systems for the creation of fully biodegradable, high-performance electrohydraulic soft actuators. They reliably operate up to high electric fields, show performance comparable to non-biodegradable counterparts, and survive over 100,000 actuation cycles. Pushing the boundaries of sustainable electronics, we demonstrate a concept for growth and processing of fungal mycelium skins as biodegradable substrate material. Mycelium-based batteries allow to power autonomous sensing devices including a Bluetooth module and humidity and proximity sensors, all integrated onto mycelium circuit boards.
