![]() A comparison of the pure metric and the new hybrid methods is also given. A joint position controller for Webots, utilising the C++ API and simple P-control. The kevobot (Khepera-kevopic simulator for Webots) package contains the so-called controller written in C and the world (physical description of the robot. The implementation of a topologic graph of the explorable places using the metric map enables the robot to navigate in a more efficient manner. A topologic layer is introduced in the environment exploration phase replacing the older value iteration. ![]() As a continuation of that research I created an enhancement of the former processes, a hybrid metric-topological navigation mechanism. Formerly I presented a metric navigation method based on occupancy grid working in the Webots simulation environment. A brief introduction to the probabilistic navigation techniques concerning Kalman filter and expectation maximization is included with a special focus on occupancy grid. In this paper a short overview is given about the problems arising in the process of the navigation, and a short taxonomy is presented about the possible problem solving methods. This is a simple example of C/C++ controller programming with Webots: a trivial collision avoidance behavior. From this web interface, users can program robots in Python and learn robot control in a step-by-step procedure. Various guidance principles can be developed in C/C++ or Java programming language with the use of Webots controller programs. Webots instances are running in the cloud and the 3D views are displayed in the user browser. Moreover, any Webots controller can be connected to a third party software program, such as MatLab, LabView, Lisp, etc. A similar Java programming interface is also included. Webots is a well-known representant of these programs, a three-dimensional mobile robot simulator. This is a reference project that shows how to build controllers for the Webots robot simulator using the Rust. The robot will stop moving if the distance sensor detects an obstacle and restart moving when the obstacle is no longer detected. ![]() True or 1 means that location is occupied by some objects, False or 0 represents a free space. The map is represented as a grid of evenly spaced binary (random) variables. Robot simulators are useful designing and analizing tools of this domain. The occupancy grid mapping is about creating a 2D map of the environment from sensor measurement data assuming that the pose is known. Transfers controllers to real mobile robots, including Aibo. Mobile robotics and robot navigation is a growing area of scientific research. Lets you program the robots in C, C++ and Java, or from third party software through TCP/IP.
