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  • The current plugin is in a very experimental state (no longer maintained) and was created to test the capabilities of having a robot simulator in Unreal Engine.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.
