 My name is Sergey Vonshakov. I am co-founder and software architect and project with the name Robonomous Network. We started this project in 2015 as a research project to use Ethereum in robotics fields. And we did a lot of experiments in the last four years with robotics and Ethereum computer. So in my presentation I will share using my experience and show you some use cases that were found where you can use Ethereum computer today in robotics fields. So let's start from history and you can find first mention of using smart contracts in robotics fields in 1997 in article by Nik Zaba, the idea of smart contracts. In this article Nik Zaba described example of using smart contracts as a list agreement with connected IoT devices. So when I found this article in 2014, it's the same time Vitalik published Ethereum by web or so from the beginning. I started working in Ethereum community to try to use Ethereum with robotics experiments. Why? Why I think Ethereum can be interesting in robotics fields. Look on this slide. It's how we use robotics as a services today and in the course of future. Humans send financial transaction to IT companies and IT companies send coins to robotics. So we have two separated data flows, financial transactions and technical transactions. In fact, with Ethereum we can send directly transactions with money and coins from humans directly to machines. It means we can combine technical and economical details into one transaction with Ethereum computer. And with that this opportunity we can imagine future of the cities, smart cities under Ethereum control. Because in other cases we will see smart cities under cloud systems control. So for me Ethereum will be better than cloud in smart cities. And about our experience. This is our first experience, it's a really funny experience. As you can see on this picture our software developer sit on the chair in winter in Russia, in the center of the fields and create first ever smart contract between human and machine. I recommend you come this current court and find two minutes after writing talks to watch this video on YouTube. After that we did a lot of other experience with the water drones, with the drones and pollution sensors, with industrial manipulators, with the simulations of self-driving cars and lights out factories. And today we found some topics where Ethereum today can be used for in robotic fields. First of all this is IoT data marketplace for sensitive data. Data where we want to have more transparency. For example IoT devices on green finance markets. Second is it's industry4.0. Today with Ethereum we can send our order from that site directly to smart factory with your options and with the money in order without intermediaries. Next is a trackable supply chain. We can collect data on factories from IoT sensors and put hash of this data in Ethereum to create additional value for products with attraction. And the last one what we found is we can use Ethereum as an admin traffic management system for self-driving cars and ground delivery services in smart cities. So everything what we did with experiments you can find in open source on GitHub and it's not only just open source of all this experience. It's a common framework what you can use today for your IoT smart city or industry4 projects. So try to use it and if you have some questions find me here on the Confine. Thank you for your time.
