Multirotor Unmanned Aerial Vehicles (UAV) have grown in popularity for research and education, overcoming challenges associated with fixed wing and ground robots. Unfortunately, extensive physical testing can be expensive and time consuming because of short flight times due to battery constraints and safety precautions. Simulation tools offer a low barrier to entry and enable testing and validation before field trials. However, most of the well-known simulators today have a high barrier to entry due to the need for powerful computers and the time required for initial set up. In this paper, we present OpenUAV, an open source test bed for UAV education and research that overcomes these barriers. We leverage the Containers as a Service (CaaS) technology to enable students and researchers carry out simulations on the cloud. We have based our framework on open-source tools including ROS, Gazebo, Docker, PX4, and Ansible, we designed the simulation framework so that it has no special hardware requirements. Two use-cases are presented. First, we show how a UAV can navigate around obstacles, and second, we test a multi-UAV swarm formation algorithm. To our knowledge, this is the first open-source, cloud-enabled testbed for UAVs. The code is available on GitHub: https://github.com/Open-UAV.

Despite the known benefits of simulations in the study of mixed energy systems in the context of smart grid, the lack of collaboration facilities between multiple domain experts prevents a holistic analysis of smart grid operations. Current solutions do not provide a unified tool-chain that supports a secure and collaborative platform for not only the modeling and simulation of mixed electrical energy systems, but also the elastic execution of co-simulation experiments. To address above limitations, this paper proposes a design studio that provides an online collaborative platform for modeling and simulation of smart grids with mixed energy resources.
