📄️ The Digital Twin: Simulating Physics in Gazebo
Welcome to the world of the digital twin, where we forge a virtual copy of our robot to test, train, and iterate without risking physical hardware. Our primary tool for this is Gazebo, a powerful 3D robotics simulator that allows us to model not just the robot, but the world it lives in—complete with gravity, friction, and collisions.
📄️ High-Fidelity Rendering and Human-Robot Interaction in Unity
While Gazebo provides a robust physics simulation, Unity excels at creating photorealistic, visually immersive, and highly interactive environments. For Physical AI, especially in the domain of humanoid robotics, high-fidelity rendering is not just an aesthetic enhancement—it's a critical component for training and validating perception systems, generating realistic synthetic data, and designing intuitive Human-Robot Interaction (HRI) scenarios.
📄️ The Digital Twin: Simulating Sensors (LiDAR, Depth, IMU)
A robot is blind and numb without its sensors. To develop an intelligent agent, we need to provide it with a stream of data that accurately represents what it would perceive in the real world. In simulation, this is achieved through sensor plugins. These are small, loadable modules that attach to a robot's model and generate realistic sensor data based on the state of the simulated world.
