Low-Level Control of a Quadrotor With Deep Model-Based Reinforcement Learning Abstract: Designing effective low-level robot controllers often entail platform-specific implementations that require manual heuristic parameter tuning, significant system knowledge, or long design times. In this paper, we present a method to control a quadrotor with a neural network trained using reinforcement learning techniques. 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. Control of a quadrotor with reinforcement learning. In this paper, we present a method to control a quadrotor with a neural network trained using reinforcement learning techniques. Create a robust and generalized quadrotor control policy which will allow a simulated quadrotor to follow a trajectory in a near-optimal manner. Our method is With reinforcement learning, a common network can be trained to directly map state to actuator command making any predefined control structure obsolete for training.

Gandhi et al. Utilize an OpenAI Gym environment as the simulation and train using Reinforcement Learning. Landing an unmanned aerial vehicle (UAV) on a ground marker is an open problem despite the effort of the research community. In this paper we propose instead a different approach, inspired by a recent breakthrough achieved with Deep Reinforcement Learning (DRL) [7]. However, previous works have focused primarily on using RL at the mission-level controller. In the past I also worked on exploration in RL, memory in embodied agents, and stochastic future prediciton. Meta-Reinforcement Learning for Robotic Industrial Insertion Tasks. 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. Reinforcement learning for quadrotor swarms. 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. As the quadrotor UAV equips with a complex dynamic is difficult to be model accurately, a model free reinforcement learning scheme is designed. Such a control policy is useful for testing of new custom-built quadrotors, and as a backup safety controller.
