Vision-Based Robotic Picking

Small, irregular metal components are difficult to pick reliably at industrial scale. For a manufacturing client, NTT DATA designed an end-to-end, vision-based pick-and-place solution combining pose estimation, grasp strategy, cycle control, high-fidelity simulation and lab validation. The initiative integrated and tested the solution in a laboratory setting, with a single-robot architecture as the target industrial design.

Coordinated vision, grasping and motion for flexible robotic handling

Bringing vision, grasping and motion control into one coordinated cycle, so a robotic cell can handle greater part variability with a clearer path from lab validation to industrial deployment.

A two-robot process and highly variable metal parts made reliable picking, cell simplification and industrial rollout inseparable engineering challenges
Objectives
The initiative set out to industrialize a scalable pick-and-place process for small, highly variable and irregular metallic components. This required robust pose estimation, reliable grasping and coordinated task execution, while redesigning the cell around a single robot and validating its behavior virtually before shop-floor integration.
Opportunity
With the lab-validated simulation environment, control software and parameterized model-tuning approach in place, the client has a foundation for onboarding additional part references without re-engineering the complete process. The next opportunity is to extend the architecture across further product families, confirm performance under production conditions and use measured operating data to refine cycle time, stability, maintenance and quality outcomes.
Turning part variability into a repeatable robotic cycle

The challenge went beyond recognizing an object. The cell had to perceive, grasp and move irregular components consistently, while reducing architectural complexity and limiting deployment risk.

Key Challenges

1: Perceiving irregular components
Small metallic parts arrived in different shapes, orientations and levels of occlusion. The initiative required robust pose estimation that could adapt to new variants without starting each model from scratch.

2: Engineering a dependable grasp
Pose alone was not enough. The gripper strategy had to accommodate complex geometries, including a slider body and puller, and support more stable handling across the cycle.
Two industrial robot arms share a tightly configured manufacturing cell with duplicated equipment, guarding and cabling.
3: Consolidating two robotic steps
The existing flow used two robotic arms for the full activity. The target architecture needed one robot to execute both steps, with coordinated task logic and cycle management.
Two robotics engineers validate a pick-and-place cell in a laboratory using calibration targets and physical test fixtures.
4: Validating before the shop floor
Physical trial-and-error during commissioning could increase integration effort and disrupt production. The solution therefore required high-fidelity simulation and iterative laboratory testing before shop-floor integration.
Solution
One coordinated intelligence layer from perception to execution

NTT DATA connected the virtual model, perception models, gripper strategy and cycle-control software into an end-to-end approach, then integrated and tested it in a laboratory environment.

Impact
A clearer path to industrial-scale picking

The initiative established an industrialization-ready foundation made up of reusable digital-twin assets, control software and a lab-validated technical roadmap. It supports lower-effort variant onboarding, fewer physical iterations before deployment and a simpler cell architecture. The source also identifies potential gains in picking stability, availability and scrap reduction; these outcomes remain subject to confirmation with production data and an agreed measurement baseline.
