The YCB Benchmarks website provides a comprehensive object and model database designed to facilitate reproducible research in robotic manipulation. Researchers around the world can access high-resolution RGB-D scans and detailed mesh representations of everyday objects to integrate into their simulation and planning pipelines. These standardized digital assets enable consistent performance comparisons across different robotic platforms and algorithms. By offering a common set of physical items and corresponding virtual models, the YCB initiative simplifies the process of evaluating manipulation strategies under controlled conditions. The website further supports community engagement through protocols documentation and result submission features that encourage collaborative benchmarking. Accessing the database requires the user to register, after which they can download models for integration into various software frameworks. The open availability of these models promotes transparency and accelerates innovation by reducing the overhead associated with dataset creation. This resource has become a reference point for roboticists seeking to streamline the development and validation of grasping and manipulation methods .
Collection of YCB 3D Models
The collection of YCB object models relies on a sophisticated multi-sensor scanning rig that captures both geometric and visual information for each item. The setup includes five calibrated RGB-D sensors and five high-resolution RGB cameras positioned along a quarter-circular arc around the object. During acquisition, each object is placed on a computer-controlled turntable that rotates at three-degree increments to produce 120 distinct orientations. At every orientation, synchronized captures from all sensors yield dense point clouds and textured meshes that faithfully represent the object’s shape, color, and surface characteristics. Researchers can directly import these 3D assets into simulation environments to conduct manipulation experiments without the need for custom scanning procedures. The resulting model database supports a wide range of research tasks, including grasp planning, object recognition, and physics-based control. This uniform data acquisition process ensures consistency and repeatability across the entire object set. Such meticulous scanning protocols form the backbone of reliable benchmarking in robotic manipulation research .
Applications in Robotic Simulation
In modern robotics research, accurate simulation plays a critical role in accelerating algorithm development and lowering experimental costs. YCB object models have been integrated into numerous software frameworks to allow virtual testing before hardware deployment. Simulations using these models can reproduce physical interactions with high fidelity, enabling the evaluation of grasp stability, force distribution, and dynamic behavior under varying conditions. Virtual environments built around the YCB mesh assets support both classical control approaches and data-driven methods such as reinforcement learning. Researchers can benchmark performance metrics like success rate, completion time, and energy efficiency across different models and tasks. The use of standardized models also facilitates the sharing of reproducible code and experimental setups among institutions. By leveraging the YCB dataset, developers minimize the time spent on asset creation and can focus on refining core algorithms. This suitability for benchmarking has led to widespread adoption of YCB assets in simulation-based robotics research .

Integrating YCB Models into Software Platforms
Integrating YCB models into manipulation pipelines requires attention to software compatibility and coordinate alignment. Most robotics middleware systems, including ROS and MoveIt!, support the inclusion of mesh files in URDF or SDF formats for collision and visualization purposes. Users should verify that the coordinate frames defined in the object URDF match the expected base and tool frames of their simulation or real robot. It is also important to ensure that mesh units correspond to the robot’s unit conventions, typically meters in most physics engines. Texture files accompanying the RGB-D data must be correctly referenced to preserve realistic object appearances in visual simulations. Advanced users may preprocess meshes to simplify geometry for faster collision checking, while retaining enough detail to avoid inaccuracies in contact modeling. Automation scripts can batch-convert files into required formats and apply transformations to align all assets to a common reference frame. Proper version control of processed models helps maintain consistency across different experiments and research projects .
Best Practices and Preprocessing
Preprocessing of YCB object models is crucial for optimizing simulation performance and ensuring data quality. Mesh simplification algorithms can reduce polygon counts while maintaining important shape features, which helps decrease computational overhead during collision detection. Checking mesh integrity for non-manifold edges, inverted normals, and duplicate vertices prevents simulation errors and unrealistic interactions. Calibrating physical properties such as mass distribution, friction coefficients, and material textures enhances the realism of dynamic manipulation tasks. Researchers should also consider generating alternative mesh resolutions to balance between detail fidelity and processing speed, depending on their experimental needs. Proper documentation of any modifications applied to the original models ensures transparency and reproducibility in published results. Collaborative versioning platforms like Git or SVN enable teams to track changes and roll back to previous model states if discrepancies arise. Maintaining a clear overview of preprocessing steps streamlines the integration of YCB assets into diverse research workflows .
