Franka Description

Overview

The Franka Description repository offers all Franka Robotics models. It includes detailed 3D models and essential robot parameters, crucial for simulating these robots in various environments. Additionally, the repository provides a feature to create URDFs (Unified Robot Description Format) for the selected Franka robot model.

Features

Comprehensive 3D Models: Detailed 3D models of all Franka Robotics models for accurate simulation and visualization.
Robot Parameters: All necessary robot parameters for realistic and reliable simulations.
URDF Creation: Ability to create URDF files for any selected Franka robot model, essential for robot simulations in ROS and other robotic middleware.

Prerequisites

Docker

URDF Creation

To start the generation, execute the start.sh script. The arguments passed to the sh script will be used from the create_urdf.py.

# Start the generation of the urdf model
./scripts/create_urdf.sh <robot_id> <ee_id>

The urdf generation is performed by the create_urdf.py script which offers several parameters to customize the output urdf model:

usage: create_urdf.py [-h] [--robot-ee] [--no-ee] [--with-sc] [--abs-path] [--host-dir HOST_DIR] [--only-ee] [--no-prefix] robot_model

Generate franka robots urdf models. Script to be executed from franka_description root folder!

positional arguments:
  robot_model          id of the robot model (accepted values are: fr3, fp3, fer, multi_arm, none)

optional arguments:
  -h, --help           show this help message and exit
  --robot-ee           id of the robot end effector (accepted values are: franka_hand, cobot_pump)
  --no-ee              Disable loading of end-effector (robot-ee would be ingnored if set) [WARNING: this argument will be removed in future releases, introducing "none" as ee id].
  --with-sc            Include self-collision volumes in the urdf model.
  --abs-path           Use absolute paths.
  --host-dir HOST_DIR  Provide a host directory for the absolute path.
  --only-ee            Get URDF with solely end-effector data
  --no-prefix          Override the robot prefix of links, joints and visuals in the urdf file.

Visualize via ROS2

franka_description is offered as a ROS2 package. The urdf file can be visualized via RViz with the following command:

# visualize_franka.sh launches the visualize_franka.launch.py in a ros2 instance running in the docker container
# The arguments given to the .sh script are forwarded as launch arguments
# Accepted launch arguments are:
#     arm_id - accepted values are: fr3, fp3, fer
#     load_gripper - accepted values are: true (default ee_id is franka_hand), false (ee_id will be ignored) [WARNING: this argument will be removed in future releases, introducing "none" as ee id]
#     ee_id - accepted values are: franka_hand, cobot_pump

./scripts/visualize_franka.sh arm_id:=<robot_id>
