Thus, the objective of this work is to learn the residual errors between a kinematic and/or simulator model and the real robot. We evaluate our algorithm on a set of randomly generated obstacle maps, intermediate waypoints, and start-goal pairs, with results indicating a significant reduction in computational costs, with high accuracies and robust control.Īchieving highly accurate kinematic or simulator models that are close to the real robot can facilitate model-based controls (e.g., model predictive control or linear-quadradic regulators), model-based trajectory planning (e.g., trajectory optimization), and decrease the amount of learning time necessary for reinforcement learning methods. Our approach makes use of a global planner (to find the next best waypoint at any instant), a local planner (to plan the path to a specific waypoint), and an adaptive Model Predictive Control strategy (for robust system control and faster maneuvers). To address these challenges, we present a multiple waypoint path planner and controller stack for navigation in unknown indoor environments where waypoints include the goal along with the intermediary points that the robot must traverse before reaching the goal. Along with this, these works often prove optimality for single-start single-goal worlds. To date, quite a lot of work has been done in this field, but these methods often fail to find the optimal balance between computationally inexpensive online path planning, and optimality of the path. Indoor motion planning focuses on solving the problem of navigating an agent through a cluttered environment. It is now the main commercial product available from Cyberbotics Ltd. WebotsTM has been developed in collaboration with the Swiss Federal Institute of Technology in Lausanne, thoroughly tested, well documented and continuously maintained for over 7 years.
You can program these robots using your favorite development environment, simulate them and optionally transfer the resulting programs onto your real robots. You can equip each robot with a large number of available sensors and actuators. For each object, you can define a number of properties, such as shape, color, texture, mass, friction, etc. WebotsTM lets you define and modify a complete mobile robotics setup, even several different robots sharing the same environment. The provided robot libraries enable you to transfer your control programs to several commercially available real mobile robots.

Webots step code#
This is part of the code I wrote (where I want to introduce the pause). I am using Windows OS.Ĭan someone let me know if there is a way to pause the simulation when a certain event happens? I am writing my controller in C programming language.
I am building a little maze solver project using Webots.
