It is designed to subscribe to various topics published by other nodes in the system (e.g., robot state, VR controller input, camera imagery) and save them in a structured format suitable for offline analysis, training, and visualization with tools like Foxglove Studio. + +## Key Features + +- **Asynchronous Writing:** Uses a dedicated writer thread and a message queue to prevent I/O operations from blocking ROS 2 subscriber callbacks, ensuring high-frequency data capture. +- **Configurable Topics:** The specific topics to record and their message types are defined in a YAML configuration file (`recorder_config.yaml`). +- **Customizable Schemas:** While it can leverage `mcap_ros2.ROS2Writer` for standard ROS 2 messages (recommended), it also supports custom JSON schemas for specific data structures (e.g., a combined robot/controller state for training datasets).

-This module provides a complete simulation environment for the Franka FR3 robot arm, allowing you to test and develop teleoperation control without requiring physical hardware. - -## Features - -- **Accurate FR3 kinematics**: Based on official DH parameters and specifications -- **PyBullet physics simulation**: Realistic 3D visualization with physics engine -- **Socket interface compatibility**: Mimics the real robot server interface exactly -- **VR teleoperation support**: Fully integrated with the Oculus VR server -- **Joint limits and workspace bounds**: Enforces realistic robot constraints -- **Gripper simulation**: Simulates gripper open/close states - -## Components - -### 1. `fr3_robot_model.py` - -The core robot model implementing: - -- Forward kinematics using DH parameters -- Joint limit checking and enforcement -- Jacobian calculation for inverse kinematics -- FR3-specific parameters (joint limits, torques, etc.) - -### 2. `fr3_pybullet_visualizer.py` - -PyBullet-based 3D visualization system featuring: - -- Real-time robot pose rendering with physics -- End-effector trajectory tracking -- Workspace boundary visualization -- Target marker display -- Camera image capture support - -### 3. `fr3_sim_controller.py` - -Simulated robot controller providing: - -- Position and orientation control -- Simplified inverse kinematics -- Smooth motion with PD control -- Thread-safe state management -- Trajectory recording capabilities - -### 4. `fr3_sim_server.py` - -Network server that: - -- Provides the same ZMQ socket interface as the real robot -- Handles FrankaAction commands -- Publishes FrankaState messages -- Supports all standard robot operations (reset, move, gripper control) - -## Usage - -### Running with VR Teleoperation - -To use the simulated robot with VR control: - -```bash -# Start the Oculus VR server in simulation mode -python oculus_vr_server.py --simulation - -# Optional: disable visualization for headless operation -python oculus_vr_server.py --simulation --debug -``` - -### Standalone Simulation Server - -To run just the simulation server: - -```bash -# With visualization -python -m simulation.fr3_sim_server - -# Without visualization (headless) -python -m simulation.fr3_sim_server --no-viz -``` - -### Testing the Simulation - -Run the test suite to verify functionality: - -```bash -cd simulation -python test_simulation.py -``` - -This will test: - -- Forward kinematics calculations -- PyBullet 3D visualization -- Trajectory visualization -- Controller functionality - -### Programmatic Usage - -```python -from simulation.fr3_robot_model import FR3RobotModel -from simulation.fr3_pybullet_visualizer import FR3PyBulletVisualizer -from simulation.fr3_sim_controller import FR3SimController - -# Create robot model -robot = FR3RobotModel() - -# Calculate forward kinematics -pos, quat = robot.forward_kinematics(robot.rest_pose) - -# Create PyBullet visualizer -viz = FR3PyBulletVisualizer(robot) -viz.update_robot_pose(robot.rest_pose) - -# Create controller -controller = FR3SimController(visualize=True) -controller.start() -controller.set_target_pose(target_pos, target_quat, gripper_state) -``` - -## Robot Specifications - -The simulation uses accurate FR3 specifications: - -- **Degrees of Freedom**: 7 -- **Joint Limits**: Enforced based on FR3 documentation -- **Workspace**: - - X: 0.2 to 0.75 m - - Y: -0.4 to 0.4 m - - Z: 0.05 to 0.7 m -- **DH Parameters**: Based on modified DH convention -- **Home Position**: Configured for optimal workspace reach - -## PyBullet Visualization Features - -When visualization is enabled: - -- Real-time 3D rendering with physics engine -- Robot model loaded from URDF (Panda model used as FR3 proxy) -- Green trajectory lines show end-effector path -- Gray wireframe shows workspace boundaries -- Red sphere indicates target position -- Gripper fingers animate open/close -- Camera viewpoint can be adjusted interactively - -## Network Interface - -The simulation server provides: - -- **Control Port**: 8901 (REQ/REP for commands) -- **State Port**: 8900 (PUB/SUB for state updates) -- **Message Format**: Pickled FrankaAction/FrankaState objects -- **Update Rate**: 100Hz state publishing - -## Dependencies - -The simulation requires: - -- `numpy`: Numerical computations -- `scipy`: Rotation mathematics -- `pybullet`: Physics simulation and visualization - -Install with: - -```bash -pip install numpy scipy pybullet -``` - -## Limitations - -- Simplified inverse kinematics (uses Jacobian pseudo-inverse) -- No collision detection between links -- Gripper is binary (open/close) rather than continuous -- Uses Panda URDF as FR3 model (very similar kinematics) - -## Future Enhancements - -Potential improvements: - -- Custom FR3 URDF model -- Full inverse kinematics solver -- Collision detection -- Force/torque simulation -- Multiple robot support -- Integration with camera simulation diff --git a/simulation/__init__.py b/simulation/__init__.py deleted file mode 100644 index 1992f8b..0000000 --- a/simulation/__init__.py +++ /dev/null @@ -1,3 +0,0 @@ -""" -Franka FR3 Robot Simulation Module -""" \ No newline at end of file diff --git a/simulation/fr3_pybullet_visualizer.py b/simulation/fr3_pybullet_visualizer.py deleted file mode 100644 index 0ec0ca6..0000000 --- a/simulation/fr3_pybullet_visualizer.py +++ /dev/null @@ -1,301 +0,0 @@ -""" -FR3 Robot PyBullet Visualizer -
