What Bin Picking Means on Your Shop Floor
Bin picking is the automated removal of parts from a bin or container by a robot. It uses 3D vision to locate each part, determine its position and orientation, and grip it without collision. The term means parts handling in manufacturing, not storage bins or order picking in a warehouse.
In your plant, parts arrive in bulk in wire mesh bins or crates: castings, forgings, turned or stamped parts. Today an operator removes them one by one, aligns them, and loads the machine. A bin picking robot does that step instead.
Key Takeaways
Bin picking rarely fails at the camera. It fails at the interplay of detection, gripper, motion inside the bin, and handover to the machine.
Our vision models learn from CAD data and synthetic images, so a new variant needs a CAD model, not a photo shoot.
The simplest variant that runs reliably is often semi-structured, not random bin picking.
What You Gain from the Bin Picking Cell
Operators freed for skilled work
The cell takes over loading and frees up to 80% of the time an operator spends at the bin for higher-value work.
No more pre-sorting
Parts go straight from the bin into the machine, so trays, magazines, and manual sorting are no longer needed.
Unattended shifts
The cell runs night and weekend shifts that are hard to staff.
One source for everything
Hardware, software, and integration of your bin picking system come from RobCo, not from four separate vendors.
Where Bin Picking Fails and How We Solve It
In daily production, the details decide how reliably a bin picking cell runs. These are the most common challenges and how we address them:
Shiny or dark surfaces: Reflective and low-contrast parts throw off the 3D data. We tune the vision setup and lighting during solution design and validate it on your parts.
Overlapping or entangled parts: Occlusion hides edges and locks parts together. The system plans the pick order and separates the heap step by step.
Parts in corners and at the bin bottom: The last pieces are the hardest to reach. The robot works the reachable grips first, and the parts left in the bin become a planned figure, not a line stop.
Cycle time: Grip times vary in a crowded bin. We size the cell and its part buffer to your machine's cycle.
How a Bin Picking Cell Works
A reliable cell is a chain of steps. Each link has to hold for full-scale production.
Grasp planning: The cell selects the best reachable grip and plans a collision-free path past the bin walls and neighboring parts.
Gripping: The robot picks the part with the right robotic gripper, whether vacuum, mechanical, or magnetic.
Reorientation: If the machine needs an exact position, the part goes to a centering or reorientation station first.
Handover: The robot places the part into the machine, onto a belt, or into a workpiece carrier. It handles bin emptying and signals for a bin change, tied into your line through PLC integration.
At RobCo, you configure the whole sequence in RobFlow, our no-code software. Program modules are combined via drag-and-drop, and a virtual teach-in lets you plan and adjust each step before the cell runs. No programming knowledge is needed, so your own shop-floor team can make changes later on.
Which Type of Bin Picking You Need
The way your parts arrive determines what the cell has to handle. Our advice: choose the simplest setup that runs reliably.
Random bin picking is the most demanding variant, with the highest cost and technical risk. If your parts can be presented semi-structured, you typically reach stable production faster. We evaluate the right approach with you before any investment is made.
Alfie: The Autonomous Robot That Runs the Cell
Alfie, our Autonomous Industrial Robot, handles work that changes from part to part. It senses the bin, decides each grip, and adapts to new parts, containers, and layouts instead of repeating one fixed path. Alfie learns a task in simulation or on site, then keeps improving its grip success rate in production. The result is a setup that handles variation with far less teaching than a fixed-program setup.
A Suitability Check for Your Parts
A few criteria decide whether robotic bin picking is within reach for your parts.
Part weight including the gripper stays within the robot's payload, up to 40 kg depending on configuration.
You know the surface condition: shiny, dark, or oily.
You know whether the parts tend to entangle.
Container size and depth are defined.
You know the placement accuracy the machine needs.
Cycle time and shift model are clear.
Your machine or line can connect via the interfaces the RobCo control unit supports: 28x digital I/O, Ethernet, Modbus TCP, or PROFINET.
We check the rest in the site assessment, on your real parts and bin.

Solution Design
We build the 3D concept and simulation, the safety concept, and the business case, including a feasibility study on your parts.
Deployment
We commission the cell, run acceptance testing, train your team, and keep the software current with over-the-air updates.
Proven in Production
At automotive supplier Linamar Valvetrain, operators used to be tied to a single machine. With a RobCo cell, personnel efficiency in the process rose by 50%. At zinc die caster Kaspar Lüther, a RobCo cell transfers parts between two CNC lathes, and the plant runs its shifts without additional staff.
Our success stories show these and other projects in detail.
The Economics of a Bin Picking System
You pay a monthly rate, not a large upfront investment. Hardware, software, integration, and service are covered by one rate, so the cell does not tie up capital. The return comes from freed operator hours and unattended shifts. Pre-sorting into trays and magazines is eliminated, and machine downtime drops.
Frequently Asked Questions
Bin picking is the robotic removal of parts from a bin or container in manufacturing. A 3D vision system locates each part and determines its position and orientation, then the robot grips it without collision. The part goes to a machine, belt, or carrier next.
Structured bin picking handles parts that lie ordered in layers or trays, so simpler vision suffices. Random bin picking handles parts dumped in bulk, which needs 3D vision, collision-free motion planning, and often part reorientation. Semi-structured cases sit between the two and are usually faster to deploy reliably.
In 3D bin picking, a 3D vision system scans the bin and builds a point cloud. The software detects each part, estimates its pose, and plans a collision-free grip. The robot picks the part with a suitable gripper, optionally reorients it, and hands it over to the machine or conveyor.
Rigid parts are the best fit, from castings and forgings to turned and stamped parts. Weight including the gripper must stay within the robot's payload. Surface, entanglement, and the required placement accuracy decide the approach, which we confirm on your real parts.
Yes, with the right setup. Shiny and dark surfaces are a known challenge, because they distort 3D data. We tune the vision system and lighting to your parts during solution design. Then we validate the pick success rate before deployment, so reflective metal stays reliable in production.
Robotic bin picking is fast enough when it keeps pace with your machine’s cycle time. That is the real benchmark, not human speed. Grip times vary with part geometry, surface, and how the parts lie in the bin. A small part buffer absorbs slower grips, so the machine keeps running.
RobCo works on a monthly rate rather than a one-time investment, so there is no large upfront cost. The rate covers hardware, software, integration, and service. Cost drivers include part complexity, the bin picking variant, cycle time, and the gripper. We calculate your case in the site assessment.
Alfie, RobCo's Autonomous Industrial Robot, takes on bin picking jobs that change from part to part. It handles mixed, unsorted parts and new variants without re-teaching the cell for each change. That also makes it a fit for machine tending and other high-variance work.
