A robotics simulator is used to create embedded applications for a robot without depending physically on the actual machine, thus saving cost and time. In some case, these applications can be transferred on the real robot (or rebuilt) without modifications. The term ''robotics simulator'' can refer to several different robotics simulation applications. For example, in mobile robotics applications, behavior-based robotics simulators allow users to create simple worlds of rigid objects and light sources and to program robots to interact with these worlds. Behavior-based simulation allows for actions that are more biological in nature when compared to simulators that are more binary, or computational. In addition, behavior-based simulators may "learn" from mistakes and are capable of demonstrating the anthropomorphic quality of tenacity. One of the most popular applications for robotics simulators is for 3D modeling and rendering of a robot and its environment. This type of robotics software has a simulator that is a virtual robot, which is capable of emulating the motion of an actual robot in a real work envelope. Some robotics simulators use a physics engine for more realistic motion generation of the robot. The use of a robotics simulator for development of a robotics control program is highly recommended regardless of whether an actual robot is available or not. The simulator allows for robotics programs to be conveniently written and debugged off-line with the final version of the program tested on an actual robot. Of course, this primarily holds for industrial robotic applications only, since the success of off-line programming depends on how similar the real environment of the robot is to the simulated environment. ''Sensor-based'' robot actions are much more difficult to simulate and/or to program off-line, since the robot motion depends on the instantaneous sensor readings in the real world. == Features == Modern simulators tend to provide the following features: * Fast robot prototyping * * Using the own simulator as creation tool ((Virtual Robot Experimentation Platform ), Webots, R-Station, Marilou). * * Using external tools. * Physics engines for realistic movements. Most simulators use ODE ((Gazebo ), (LpzRobots ), Marilou, Webots) or PhysX (Microsoft Robotics Studio). * Realistic 3d rendering. Standard 3d modeling tools or third party tools can be used to build the environments. * Dynamic robot bodies with scripting. C, C++, Perl, Python, Java, URBI, MATLAB languages used by Webots, Python used by Gazebo. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「robotics simulator」の詳細全文を読む スポンサード リンク
