simData

This is the dataset of our RA-L work 'Learning Affordance Segmentation for Real-world Robotic Manipulation via Synthetic Images'. The detector jointly learns detection and affordance map prediction in an unsupervised manner via synthetic data. The original paper can be found here. The final version will be updated after publication process.

Usage

Please follow the instructions in Image Saver

This repo contains sketchup 3D models from 3D warehouse, compatible with UMD affordance dataset. This dataset is collected for simulation in Gazebo to automatically generate affordance annotations.

View in Gazebo (gui)

1. put the .dae model under ~/.gazebo/models/MODEL_NAME/meshes/
2. create a model.config as below in ~/.gazebo/models/MODEL_NAME/

<?xml version="1.0"?>
<model>
  <version>1.0</version>
  <name>scissors</name>
  <sdf version="1.4">model.sdf</sdf>

  <description>
    A model of for testing
  </description>
</model>

3. create a model.sdf as below in ~/.gazebo/models/MODEL_NAME/

<?xml version='1.0'?>
<sdf version="1.4">
<model name="MODEL_NAME">
  <pose>0 0 0.0 0 0 0</pose>

        <inertia> <!-- inertias are tricky to compute -->
          <!-- http://gazebosim.org/tutorials?tut=inertia&cat=build_robot -->
          <ixx>0.083</ixx>       <!-- for a box: ixx = 0.083 * mass * (y*y + z*z) -->

4. open Gazebo roscore & rosrun gazebo_ros gazebo and you can insert the model

Add/Delete in Gazebo (script)

1. follow step 1&2&3 as above to prepare the model
2. open an empty world roscore & rosrun gazebo_ros gazebo
3. add model

rosrun gazebo_ros spawn_model -sdf -z 1 -file /home/USERNAME/.gazebo/models/MODEL_NAME/model.sdf -model MODEL_NAME

4. delete model

rosservice call gazebo/delete_model '{model_name: MODEL_NAME}'

arg in spawn_model can be used to specify 6DOF of the position for placing
