URoboSim (DEPRECATED)

Unreal engine based robot simulator.

DEPRECATED

• The current plugin is in a very experimental state (no longer maintained) and was created to test the capabilities of having a robot simulator in Unreal Engine.
• Currently maintained version is located here: https://github.com/urobosim/URoboSim
• We are currently working on a new version using a different approach. Early state of PR2:

Features

• Import a URDF file into UE4 by drag & drop into the content browser. A new asset is created with the URDF information. Before dragging the asset into the game world, certain properties can be edited using a new visual interface found in the Editor Mode window.

• As an optional feature, this project can be run with the UROSBridge plugin to control the imported robot from a ROS server through websockets.

• The URDF can be placed inside a folder called XML which should be in the same directory as the Unreal Engine Project File.

• Note that if the URDF uses meshes, it likely keeps them in one or more folders.

• Make sure that for each robot within the XML folder, the file system reflects the structure that the URDF expects.

• For example, for the pr2, it expects to find the wheel mesh here: "pr2_description/meshes/base_v0/wheel.dae". So in the same directory as the pr2.urdf, there should be a folder called pr2_description which contains the subsequent folders and file.

• Be sure to check the Wiki page for more details.

• See here PR2 Packages for ROS Kinetic Kame.

• See the ex-ros-tf-robosim branch of RobCoG as an Unreal Project example with PR2 UROSBridge communication and TF publishing with UTFPublisher.
