Work in progress

This project is still under active development and is not yet fully functioning end to end. It currently requires an NVIDIA GPU and a working NVIDIA container runtime.

IsaacSim Store Shelf

ROS 2 Isaac Sim + MoveIt/cuMotion pipeline for dual-arm YuMi shelf picking, with vision-driven target selection and direct trajectory execution.

I built it to learn the modern Isaac Sim and ROS 2 manipulation stack, push cuMotion toward coordinated multi-arm planning, and explore how simulation, perception, and motion planning fit together in one system.

Components

• docker-compose.yml, Dockerfile.ros2, Dockerfile.isaacsim

  • Uses Docker Compose with GPU passthrough via gpus: all, /dev/dri, NVIDIA_VISIBLE_DEVICES=all, and NVIDIA_DRIVER_CAPABILITIES=all.
  • Defines a ROS 2 Jazzy service for workspace builds, training, inference, MoveIt, cuMotion, and launch orchestration.
  • Defines an Isaac Sim 5.1.0 service that runs the simulation manager with the Isaac Sim Python runtime.
  • Supports headed and headless Isaac Sim startup through manager commands and launch arguments.
  • Mounts Isaac Sim cache, config, logs, and app data into repo-local .docker/isaacsim directories.

• src/isaacsim_manager

  • Uses Isaac Sim, USD, PhysX, and the Isaac Sim ROS 2 bridge to construct and run the shelf scene.
  • manager.py exposes a ROS control interface on /isaacsim_manager/control and supports start, start_headless, stop, and restart.
  • scene_construction.py loads the shelf USD, imports the YuMi URDF, adds camera frames, TF graphs, ROS camera output, static colliders, item semantics, and drop-off targets.
  • image_collection.py defines the collect_vision_data, static, and store_demo scenarios.
  • Uses Omniverse Replicator to capture RGB, instance segmentation, distance-to-camera, and per-frame metadata for vision training.
  • trajectory_executor.py implements direct FollowJointTrajectory action servers that apply planned joint trajectories to Isaac Sim articulations.
  • vision_panel.py and target_marker_visualizer.py add in-simulation debug views for model output and selected pick targets.

• src/vision

  • Uses PyTorch, torchvision, OpenCV, and ROS 2 image topics for training and inference.
  • Input is camera RGB from /camera/image_raw plus /camera/camera_info; training data comes from Replicator RGB, instance segmentation, distance-to-camera, and metadata files.
  • Output includes /vision/debug_image, /vision/predicted_identity, /vision/predicted_depth, /vision/predicted_depth_viz, /vision/predicted_occupancy, /vision/selected_item_point, and /vision/selected_item_moveit_point.
  • The model is a custom query-based depth and identity predictor.
  • The backbone is MobileNetV3 Small feature extraction followed by a 1x1 projection, learned object queries, a Transformer decoder, slot heads, and small alpha-mask patch decoders.
  • Inference chooses a visible item query, estimates a 3D camera-space point from predicted depth and camera intrinsics, then transforms it into world and MoveIt frames with tf2.

• src/motion

  • Uses ROS 2, MoveIt 2, NVIDIA Isaac ROS cuMotion, and action-based trajectory execution.
  • coordinator.py receives selected item points, assigns targets to the left or right arm, and sequences pick steps: pregrasp, grasp, close gripper, retract, move to drop, open gripper.
  • planner.py converts assigned targets into MoveIt pose goals, sends requests to MoveGroup, publishes planned trajectories for peer-arm collision awareness, and can execute through direct Isaac Sim trajectory actions.
  • occupancy.py builds collision context from the other arm and planned peer trajectories.
  • cumotion_sphere_publisher.py publishes cuMotion robot spheres for RViz debugging against the visible robot mesh.

• src/yumi_description

  • Uses Xacro as the canonical robot description source.
  • export_isaacsim_urdf generates the Isaac-ready YuMi URDF used by the simulator.
  • Keeps MoveIt and Isaac Sim derived from one robot description instead of separate hand-maintained models.

• src/yumi_moveit_config

  • Contains MoveIt 2 configuration for the YuMi arms, including SRDF, joint limits, kinematics, controllers, planning pipelines, and cuMotion configuration.
  • static_planning_scene.py publishes shelf collision objects into MoveIt and retries if the planning scene service rejects the first application.
  • RViz config rviz/cumotion_debug.rviz visualizes the robot, cuMotion spheres, attached objects, and voxel/debug topics.

• src/controller

  • Provides top-level ROS 2 launch orchestration.
  • store_demo.launch.py starts the Isaac Sim scenario, vision inference, motion coordinator/planners, MoveIt, ros2_control, and optional RViz.
  • collect_vision_data.launch.py starts the synthetic data capture scenario.
  • static.launch.py starts a lighter static visualization/debug setup.

How to run

Create Isaac Sim writable cache directories once:

mkdir -p .docker/isaacsim/cache/main .docker/isaacsim/cache/computecache .docker/isaacsim/logs .docker/isaacsim/config .docker/isaacsim/data .docker/isaacsim/pkg
sudo chown -R 1234:1234 .docker/isaacsim

Allow local X11 access for headed Isaac Sim on Linux:

xhost +local:

Build the containers:

COMPOSE_PARALLEL_LIMIT=1 docker compose build ros2 isaacsim

Start the Isaac Sim manager service:

docker compose up isaacsim

In another terminal, build and source the ROS workspace:

docker compose run --rm ros2 bash
source /opt/ros/jazzy/setup.bash
source /opt/isaac_ros_cumotion_ws/install/setup.bash
source /opt/isaac_manipulator_ws/install/setup.bash
colcon build --symlink-install
source install/setup.bash

Run the full store demo with cuMotion:

ros2 launch controller store_demo.launch.py \
  motion_pipeline_id:=isaac_ros_cumotion \
  motion_planner_id:=cuMotion

Run the same demo with RViz MoveIt/cuMotion debugging:

ros2 launch controller store_demo.launch.py \
  motion_pipeline_id:=isaac_ros_cumotion \
  motion_planner_id:=cuMotion \
  use_moveit_rviz:=true

Start the simulation in headless mode through the lower-level launch path:

ros2 launch controller sim.launch.py \
  headless:=true \
  configuration:=store_demo \
  use_moveit:=true \
  planning_pipeline:=isaac_ros_cumotion

Collect synthetic vision training data:

ros2 launch controller collect_vision_data.launch.py headless:=true

Train the vision model:

ros2 launch controller train_vision.launch.py

Run vision inference only:

ros2 launch vision inference.launch.py \
  checkpoint_dir:=/workspace/checkpoints/vision \
  image_topic:=/camera/image_raw

Export the Isaac Sim URDF after robot description changes:

ros2 run yumi_description export_isaacsim_urdf
