Simulation Tools for Robotics
1. Introduction
Simulation tools in robotics provide a virtual environment where robots can be modeled, tested, and validated without the need for physical prototypes. These tools are essential for developing algorithms, validating designs, and training robotics systems.
2. Key Concepts
- **Robot Model:** A digital representation of a robot, including its kinematics, dynamics, and sensors.
- **Environment Simulation:** The virtual setting where the robot operates, which can include obstacles, terrains, and other robots.
- **Physics Engine:** A computational engine that simulates physical interactions, such as collision detection and response.
- **Control Algorithms:** Algorithms that dictate how a robot should behave in response to its environment.
