\\ \\ ====== An Open-Source C++ Library for Robotics and Optimal Control ====== The ADRL Control Toolbox is a C++ library for efficient modelling, control and estimation for robotics. The source code is available at https://github.com/ethz-adrl/control-toolbox . The documentation can be accessed at https://ethz-adrl.github.io/ct/ ---- \\ \\ ====== TOWR - Trajectory Optimizer for Walking Robots ====== A light-weight, Eigen-based C++ library for trajectory optimization for legged robots {{:adrl:towr.png?200}} Github: https://github.com/ethz-adrl/towr ---- \\ \\ ====== IFOPT - Eigen-based interface to Nonlinear Programming Solvers====== A modern, light-weight, Eigen-based C++ interface to Nonlinear Programming solvers, such as Ipopt and Snopt. {{:adrl:ifopt.png?200}} Github: https://github.com/ethz-adrl/ifopt \\ ---- \\ \\ ====== XPP - Visualization of Legged Robot Motions in RVIZ ====== || {{:adrl:xpp.png?400}} || Xpp is a collection of ROS-packages for the visualization of motion plans for floating-base robots. Apart from drawing support areas, contact forces and motion trajectories in RVIZ, it also displays these plans for specific robots. Current robots include a one-legged, a two-legged hopper, HyQ and a quadrotor.|| ROS: http://wiki.ros.org/xpp ---- \\ \\ ====== RCARS: Robot-Centric Absolute Reference System ====== RCARS (Robot-Centric Absolute Reference System) is a ROS Metapackage that provides a lightweight and easy to use, visual inertial state estimation and/or motion capture system. It uses a Simultaneous Localization And Mapping (SLAM) approach based on aritificual landmarks ("fiducials") observed by a camera and inertial measurement data retrieved from an IMU. Yet, the system is still fast and easily integratable into existing systems.

The user should specify the initial search distribution (i.e. the mean and the covariance) then the algorithm finds a minimum of the function. We have shown the performance of ROCK* in very high dimensional systems (500 parameters) as well as low dimensional systems [1]. It outperforms the state-of-the-art algorithm, CMA-ES, sometimes by an order of magnitude. It is also very simple to implement it to different systems and objective functions due to its black-box modeling of the system.
