How 3D Vision Transforms Robotic Bin Picking

In manufacturing and logistics, one of the most challenging tasks for automation is bin picking, as it involves selecting and handling objects that are randomly piled. Because traditional robots are usually designed to perform a single, clearly defined task, they unsurprisingly struggle with parts that are stacked unevenly, overlap, or rotate unpredictably. However, adding 3D vision can overcome these limitations and give the robot the insight and accuracy needed to manage these complexities effectively.

Unstructured Picking Challenges

Robots operating without 3D vision rely on fixed positions and programmed motions, meaning that when anything unexpected occurs during bin handling, parts are often dropped or collisions with other items or the container occur. This slows production and often requires human operators to step in to correct the process, resulting in time-consuming rework. Due to these operational errors, the advantages of automation are reduced, and its use is limited in unstructured environments.

How 3D Vision Makes a Difference

The addition of 3D vision enabled robots to perceive the environment by rapidly capturing depth data and point clouds. Giving the robots a detailed understanding of each object’s shape, orientation, and location, so they can correctly calculate grasping positions, avoid collisions with other items and the bin itself, and adapt to variations in size or placement in the picking bin.

In practical terms, 3D vision-equipped robots can easily handle unstructured environments, making tasks that were once too complex for automation much more manageable.

Surface Pro Series for Bin Picking

The Revopoint Surface Pro series 3D cameras rapidly capture high-resolution depth data with ±0.05 mm precision, giving robots the spatial awareness needed to plan movements and evaluate potential grasp points. Robots equipped with the Surface Pro series will have significantly better pick consistency and be capable of handling a wide variety of parts, while greatly reducing the need for any manual intervention.

Surface Pro series key advantages:

High accuracy for detailed 3D measurement and inspection.

Fast, high-resolution depth data for reliable 3D perception.

Easy system integration with standard industrial SDKs and interfaces.

Industrial-grade design suitable for harsh factory environments.

Flexible working range and field of view for varied object sizes.

Well-suited for automation tasks like robot guidance and bin picking.

The Business Case

The advantage if implementing 3D vision-powered bin picking are clear. It greatly improves the process throughput while reducing labor costs and lowering error rates. It also makes automation easier to scale, as systems can now be trained to handle new item types without extensive reprogramming or lengthy debugging downtime.
