+The Human Worker Gem provides a collection of animated human worker assets that can be used in robotic simulations with [ROS&nbsp;2 Gem](./ros2.md) in **Open 3D Engine (O3DE)**. The human worker can navigate between the waypoints in the scene and is visible to any robots that maneuver in the same area. It uses

+This gem contains the following components:
+* Human worker mesh with textures
+* Mesh animations of human standing
+* Mesh animations of human walking
+* O3DE components for basic navigation of the human worker in a scene
+
+An example of its use can be found in [ROSCon2023Demo](https://github.com/RobotecAI/ROSCon2023Demo) project. The Gem is available from our [Github repository](https://github.com/RobotecAI/o3de-humanworker-gem). For more information, refer to the _README_ file of the Gem.

+
+The **OTTO Robots Gem** provides a collection of Autonomous Mobile Robots (AMRs) assets that can be used in robotic simulations with [ROS&nbsp;2 Gem](./ros2.md) in **Open 3D Engine (O3DE)**. In particular, this Gem contains the simplified models of the following robots developed by [OTTO Motors](https://ottomotors.com):
+- [OTTO 1500 v2](https://ottomotors.com/1500)
+- [OTTO 600](https://ottomotors.com/600)
+
+Additionally, it contains the assets of the stands:
+- High and low stands for OTTO 1500 v2
+- Stand for OTTO 600
+
+This Gem includes implementation to control lifting platforms of OTTO 600 and OTTO 1500 robots. Movement of the platform can be manually steered using PhysX Debug Gem or controlled from code using the Pid Motor Controller Component of [ROS&nbsp;2 Gem](./ros2.md). Additionally, it includes the code to control the lights of OTTO 600 via ROS 2 interfaces.
+
+An example of its use can be found in [ROSCon2023Demo](https://github.com/RobotecAI/ROSCon2023Demo) project. The Gem is available from our [Github repository](https://github.com/RobotecAI/o3de-otto-robots-gem/). For more information, refer to the _README_ file of the Gem.

+<!-- # Robotec GPU Lidar (RGL) Gem -->
+
+The **Robotec GPU Lidar (RGL) Gem** is a module working with [ROS&nbsp;2 Gem](./ros2.md) and extending it with a GPU-accelerated implementation of _Lidar Sensor Component_. It uses an open source [Robotec GPU Lidar library](https://github.com/RobotecAI/RobotecGPULidar) simulating LiDAR through raycasting based on GPU with [CUDA](https://docs.nvidia.com/cuda/) and [OptiX](https://raytracing-docs.nvidia.com/optix8/index.html). 
+
+The Gem provides a faithful representation of the simulated environment by supporting the following visuals:
+* Mesh Component
+* Terrain created using the [O3DE Terrain Gem](../environment/terrain)
+
+You can fully customize the LiDAR's settings using the O3DE Level Editor. Those include properties like:
+* configurable raycasting pattern
+* lidar range
+* entities excluded from raycasting
+
+You can also choose one of the presets provided by the ROS&nbsp;2 Gem to create a LiDAR model that fits your needs.
+
+The Gem is available from our website at [Github repository](https://github.com/RobotecAI/o3de-rgl-gem). For more information, refer to the _README_ file of the Gem and/or the [README file](https://github.com/RobotecAI/RobotecGPULidar) of the library.
