📝 Simulation & Development
Description
< What is it? >
Robotics simulation and development tools help engineers build, test, train, and operate robot software before relying on real hardware. They cover virtual environments, physics and sensor simulation, robot-learning workflows, and the middleware that connects components together.
Key points
< Core roles >
| Role | Example tool | Purpose |
|---|---|---|
| Robot and sensor simulation | Isaac Sim, Gazebo | Test robots, sensors, physics, and scenes safely in virtual environments |
| Robot learning | Isaac Lab | Train and evaluate reinforcement- or imitation-learning policies at scale |
| Middleware and integration | Robot Operating System 2 (ROS 2) | Connect robot software components, data streams, tools, and hardware drivers |
| Synthetic data and validation | Isaac Sim, Gazebo | Test edge cases and generate labeled sensor data before hardware deployment |

test, collect data, or train a policy
↓
validate with hardware and monitor the sim-to-real gap
Simulation reduces cost and risk, but it cannot perfectly reproduce real-world contacts, lighting, sensor noise, network delays, or failures. Hardware validation remains necessary.
