Make sure to use minimal light sources as long as your perception algorithms perform optimally. Only proceed to add sources of directional light if you cannot modify the default Sun model’s range and attenuation parameters to achieve your end cause.

In addition, several other controllable levers in the Gazebo ecosystem can improve performance. However, such changes can be specific to the simulated robotic system. For example, improving the performance of a robot arm while maintaining the necessary physics update would be different from simulating a 3D LiDAR in an ...

Whether you are trying to mimic an AMR, AGV, or a Robotic Arm, it is imperative to determine which hardware properties of a real-life sensor you want to emulate in Gazebo. The true bottleneck arises in simulating cameras, pointclouds, and laser scans.
