    AirSim

    AirSim

    A simulator for drones, cars and more, built on Unreal Engine

    AirSim is an open-source, cross platform simulator for drones, cars and more vehicles, built on Unreal Engine with an experimental Unity release in the works. It supports software-in-the-loop simulation with popular flight controllers such as PX4 & ArduPilot and hardware-in-loop with PX4 for physically and visually realistic simulations. It is developed as an Unreal plugin that can simply be dropped into any Unreal environment. AirSim's development is oriented towards the goal of creating a platform for AI research to experiment with deep learning, computer vision and reinforcement learning algorithms for autonomous vehicles. For this purpose, AirSim also exposes APIs to retrieve data and control vehicles in a platform independent way. AirSim is fully enabled for multiple vehicles. This capability allows you to create multiple vehicles easily and use APIs to control them.

    Cambridge Rocketry Simulator

    Simulate high power rocket flights with splash down plots

    This software allows you perform six degree of freedom simulations of High Power Rocket (HPR) and model rocket flights. Parachute descent is also simulated. 3D flight trajectories are produced as well as detailed tabular flight data. Running in Monte Carlo mode allows generates multiple possible flight paths and splash down plots, indicating the probability of landing in an area.

    Biogenesis X Mod

    Biogenesis X Mod

    Mod of the evolution simulation and artificial life program Biogenesis

    This project is a modification of the original evolution simulation & artificial life project by Joan Queralt Molina: https://sourceforge.net/projects/biogenesis/ In both, the original project and this modification, 2-dimensional organisms consisting of line segments interact with each other, reproduce and evolve in time. Compared to the original project, this modification explores the following features: * alternative mutation mechanisms * an alternative stress-based aging mechanism It is based on the new_design branch of Biogenesis (https://sourceforge.net/p/biogenesis/git/ci/new_design/tree/), its source code can be obatained from http://sourceforge.net/p/biogenesisxmod/code/ci/xmod/tree/ If you want to post a review, remember that this is only a modification, so comment on my changes, not on the simulation.
