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.

ROCK* Optimization Algorithm for Policy Learning

The ROCK* algorithm is a sampling-based nonlinear function optimizer which works with many classes of functions. 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.
