Random and semi-structured part picking

Pick loose parts from bins with 3D robot guidance.

Automate the difficult first pick from randomly or semi-structured parts using 3D vision, collision-aware paths and tooling proven against your components.

Your production outcome

Turn unstructured parts into a controlled robot process

Bin picking can remove manual part presentation, but reliability depends on whether the system can see, reach, grip and extract a usable part throughout the container.

A 3D sensor captures the surface of the bin and identifies candidate parts. Vision software estimates a pick pose, while the robot path and tooling must avoid the bin walls, neighbouring parts and fixtures. The cell then confirms the grip and presents the component to the next machine, inspection point or assembly process.

The hardest conditions are usually not the first easy picks. Tangled parts, reflective or dark surfaces, deep bins, thin edges, unstable stacks and the final layer can reduce detection or access. We review the full bin, expected contamination, replenishment method and empty-bin changeover before defining the concept.

Some applications benefit from a hybrid approach: controlled trays, step feeders or partial singulation may deliver a faster and more robust result than completely random picking. The right answer is the simplest presentation method that achieves your required output and uptime.

Start with your product and target rate

Send product details, variants, current-process photos or video, target output and available space. We will use them to identify the right feasibility work and the simplest reliable cell concept.

Design factors

What determines a reliable result.

These elements are reviewed as one production system so normal variation and fault recovery are designed in from the start.

Part geometry

Review CAD data, surfaces, symmetry, tangling risk and stable grip points across every component variant.

3D visibility

Confirm the sensor can detect useful surfaces at the required depth, angle and ambient conditions.

Robot access

Model reach, approach angles, wrist posture and clearance around bin walls and neighbouring parts.

Gripper reliability

Test vacuum, finger, magnetic or combined tooling against real part variation and contamination.

Collision management

Plan approach, extraction and retreat paths with defined behaviour when no safe pick is available.

Bin logistics

Design full-bin loading, empty-bin removal, operator access and safe replenishment into the production cycle.

Project route

From application evidence to a working cell.

Each decision is tied to your products, rate, interfaces and agreed acceptance criteria.

Assess parts

Review samples, CAD, bin size, presentation and target cycle.

Run feasibility trials

Test visibility, candidate poses, grip and extraction using representative bins.

Integrate the cell

Combine robot, 3D vision, tooling, bin handling, controls and safety.

Prove difficult cases

Validate low-bin, tangled, occluded and fault-recovery scenarios before handover.

Frequently asked questions

Clear answers about robotic bin picking.

These answers are general guidance. Final selection and performance are confirmed against your application.

What is robotic bin picking?

Robotic bin picking uses vision to locate parts presented loose or semi-structured in a container, calculates a usable pick pose and guides the robot through a safe grip and extraction path.

Can a robot pick completely random parts from a bin?

Often, but not every product is suitable. Tangling, reflective or featureless surfaces, thin parts, deep containers and limited grip access can reduce reliability. Trials with representative parts and bins are important.

Does bin picking always require 3D vision?

Random parts at different heights and poses commonly require 3D data. A simpler 2D method may work for shallow layers or semi-structured presentation where height and overlap are controlled.

What happens when the robot cannot find a safe pick?

The control strategy can request another scan, choose a different candidate, use a controlled disturbance action, ask for operator assistance or change the bin. The permitted recovery behaviour is defined during design and testing.
