Un-like the discrete problems considered introduc-tory reinforcement learning texts, a quadrotor’s state is a function of its position, velocity, and acceleration: continuous variables that do not lend themselves to quantization. Un- like the discrete problems considered introduc-tory reinforcement learning texts, a quadrotor’s state is a function of its position, velocity, and To address the challenge of rapidly generating low-level controllers, we argue for using model-based reinforcement learning (MBRL) trained on relatively small amounts of automatically generated (i.e., without system simulation) data. In our work, we use reinforcement learning (RL) with simulated quadrotor models to learn a transferable control policy.

Recent publications: (2020) Sample Factory: Egocentric 3D Control from Pixels at 100000 FPS with Asynchronous Reinforcement Learning With the popularity of machine learning a new type of black box model in form of artificial neural networks is on the way of replacing in parts models of the traditional approaches. Such a control policy is useful for testing of new custom-built quadrotors, and as a backup safety controller. To address sample efficiency and safety during training, it is common to train Deep RL policies in a simulator and then deploy to the real world, a process called Sim2Real transfer. Utilize an OpenAI Gym environment as the simulation and train using Reinforcement Learning. Applications. tive stability, applying reinforcement learning to quadrotor control is a non-trivial problem. Moreover, we present a new learning algorithm which differs from the existing ones in certain aspects. The primary job of flight controller is to take in desired state as input, estimate actual state using sensors data and then drive the actuators in such a way so that actual state comes as close to the desired state. My interests lie in the area of Reinforcement Learning, UAVs, Formal Methods and Control Theory. Jemin Hwangbo, Inkyu Sa, Roland Siegwart, and Marco Hutter.

This paper proposes an event-triggered reinforcement learning (RL) control strategy to stabilize the quadrotor unmanned aerial vehicle (UAV) with actuator saturation. Flight Controller# What is Flight Controller?# "Wait!" Robotics, 9(1), 8. However, the generation of training data by ying a quadrotor is tedious as the battery of the quadrotor needs to be charged for several times in the process of generating the training data. Gandhi et al. 1995. I was also responsible for the design, implementation and evaluation of learning algorithms and robot infrastructure as a part of the research and publication efforts at Kindred (e.g., SenseAct ).
