The YCB Benchmarks portal serves as a comprehensive resource for robotic manipulation research. The website offers a standardized object and model set developed by Yale, CMU, and Berkeley teams. This set allows researchers to evaluate algorithmic performance with consistent hardware components and data. By using daily life objects that vary in shape, size, texture, rigidity, and mass, the benchmark covers diverse manipulation challenges. Users can download high fidelity mesh models and RGB-D scans to simulate tasks before testing on physical hardware. The physical objects can be ordered through a central distribution system managed by UMass Lowell. This availability promotes reproducibility and fosters community-driven improvements in manipulation protocols. Researchers around the world rely on this platform to compare approaches and track progress over time :contentReference[oaicite:0]{index=0}.
Among the suite of tasks available on the YCB site, the Table Setting Benchmark stands out as an intuitive and practical test for robotic systems. First introduced in September 2015 by Dr. Berk Calli and colleagues, it measures a system’s pick-and-place ability with everyday utensils and tableware :contentReference[oaicite:1]{index=1}. In this protocol, a robot must grasp objects such as plates, cups, utensils, and place them accurately on a tabletop surface. The benchmark defines a precise arrangement grid and mandates specific grasp locations and object orientations. Each trial evaluates both success rate and task completion time to quantify dexterity and efficiency. This approach has become a standard for assessing manipulation capabilities across research labs. Its focus on common household items makes the benchmark relatable and easily adopted in diverse research settings. Over time, the Table Setting Benchmark has been refined with updated protocols and improved evaluation metrics.
Origins and Objectives
The primary objective of the Table Setting Benchmark is to create a fair and replicable test of in-situ robotic manipulation. Designers aimed to balance task complexity with universal accessibility by selecting a fixed set of common objects. By standardizing object properties and spatial constraints, researchers can isolate algorithmic performance from hardware variances. This protocol was motivated by the need for universal tasks that accurately reflect real-world service robotics challenges. The Table Setting task captures critical aspects of perception planning, grasp synthesis, and motion execution. Through repeated trials, the benchmark reveals strengths and weaknesses of different control strategies. It allows research groups to compare hand designs, gripper configurations, and perception pipelines. Ultimately, the benchmark’s goals include driving innovation in both hardware and software for home automation.
Methodology and Setup
To prepare for the Table Setting Benchmark, researchers must gather a predefined object set and a flat table surface. The protocol specifies the exact dimensions and positions for each item relative to a global coordinate frame. Before trials begin, the robot must initialize its coordinate reference and verify object positions with sensor data. Each run begins with objects arranged at designated start locations, preventing manual alignment variability. Robots execute pick, translate, and place motions according to a scripted sequence to emulate human-like table setting. After each placement, the system records success based on predefined tolerances for orientation and position. Failed placements or dropped items incur penalties in the final score calculation. Researchers often automate data logging to capture detailed performance metrics such as force profiles and joint velocities.

Required Equipment and Objects
The standard YCB object set for the Table Setting Benchmark includes items such as a plate, bowl, mug, spoon, fork, and knife. Each object was selected to present unique challenges in geometry, weight distribution, and surface texture. The mesh models in the database enable simulation trials to validate algorithms before deploying on hardware. High-resolution RGB-D scans provide accurate visual data for perception modules to detect and localize each object. Researchers can optionally extend the object set with additional household items to test generalization capabilities. The benchmark’s documentation details object mass, dimensions, and surface friction coefficients for transparency. By using uniform test materials, labs can ensure that variations in performance stem from control algorithms. Consumable items such as napkins or cloths are excluded to maintain consistency and reduce experimental variability.
Evaluation Metrics
Performance in the Table Setting Benchmark is quantified through a combination of accuracy, speed, and reliability metrics. Accuracy is measured by the deviation of each object’s final pose from its target pose within metric thresholds. Speed is recorded as the time elapsed from initial grasp command to final placement confirmation. Reliability is assessed by the percentage of successful placements over multiple trials. Additional metrics such as energy consumption and joint torque profiles provide insight into efficiency trade-offs. Researchers can also analyze recovery behaviors when objects slip or misalign during manipulation. Data visualization tools help compare performance across algorithms, revealing strengths in perception or control. These metrics collectively guide improvements in robotic design and algorithm development.
Applications and Impact
The Table Setting Benchmark has been widely adopted in academic and industrial research groups focused on service robotics. It provides a tangible demonstration of a robot’s ability to interact safely and effectively with everyday objects. Research teams use the benchmark results to refine grasp planning, motion execution, and sensor integration strategies. Industrial automation startups leverage the benchmark to showcase their manipulator performance in trade exhibitions. Educational institutions include the protocol in coursework to teach students about real-world robotic challenges. Notably, the Humans and Robots Laboratory at Brown University implemented the Table Setting Benchmark using YCB objects to validate their autonomous setting routines :contentReference[oaicite:2]{index=2}. By sharing results on the YCB website, the Brown team contributed to an open database of performance records. This collective effort accelerates progress towards reliable robots capable of assisting in household tasks.
