How do I ensure my bin picking workflow with a manipulation controller is compliant?

To keep a bin-picking workflow with a manipulation controller compliant, you usually need to address both regulatory and technical compliance: safety, validation, traceability, and operational controls.

Here’s a practical checklist:

1) Identify the applicable standards and regulations

Compliance depends on your region and industry, but common references include:

• ISO 10218-1 / ISO 10218-2 — industrial robot safety
• ISO/TS 15066 — collaborative robot guidance, if humans may interact nearby
• ISO 12100 — risk assessment and risk reduction
• IEC 61508 / ISO 13849 / IEC 62061 — functional safety for control systems
• OSHA / local workplace safety laws
• Machine-specific standards for end effectors, vision systems, and conveyors

If you’re in a regulated industry like medical, automotive, food, aerospace, or pharma, add the relevant sector standards.

2) Perform a formal risk assessment

Document hazards for the full workflow:

• robot motion and pinch/crush points
• gripper/end-effector hazards
• dropped parts
• unexpected startup
• sensor/vision errors
• human entry into the cell
• part collisions, jams, and recovery actions

Then define mitigations:

• safety-rated speed/force limits
• light curtains, area scanners, safety fences, interlocks
• safe zones and keep-out zones
• emergency stop behavior
• collision detection and recovery logic
• safe homing and restart procedures

3) Use a safety-rated control architecture

Make sure the manipulation controller is designed and configured so that safety functions are not dependent on ordinary software alone.

Key items:

• safety PLC or safety controller where required
• verified emergency stop chain
• safe torque off / safe stop functions
• safety-rated I/O for interlocks and sensors
• separation between safety logic and application logic
• fail-safe behavior on communication loss, sensor failure, or controller reset

4) Validate perception and grasp logic

Bin picking often fails compliance if the pick pipeline is too fragile.

You should validate:

• camera calibration and accuracy
• object detection performance across expected part variation
• grasp pose generation limits
• collision checking
• retry logic and fault handling
• rejection of uncertain detections
• tolerances for occlusion, lighting, reflections, and dirty parts

Keep evidence showing the system works within specified bounds.

5) Document operating limits

Define and enforce:

• part sizes, weights, and materials
• bin geometry and fill level limits
• allowable tool reach and speed
• payload limits
• environmental conditions: lighting, dust, vibration, temperature
• cycle-time and throughput assumptions
• recovery procedures for mispicks and jams

If the workflow runs outside those limits, it should stop or enter a safe state.

6) Add traceability and auditability

For compliance, you want to know what happened and when.

Log:

• robot/controller version
• configuration changes
• operator actions
• faults and resets
• safety events
• picks attempted, successful, failed
• vision outputs if relevant
• maintenance and calibration history

Use change control so software/configuration updates are approved and reviewable.

7) Test and validate before production

Do structured verification:

• simulated testing
• dry runs with no parts
• collision and fault injection tests
• power-loss and recovery tests
• sensor disconnect tests
• emergency stop tests
• restart-after-fault tests
• acceptance testing against documented requirements

If required, maintain a validation report signed off by responsible engineering and safety personnel.

8) Train operators and maintainers

Compliance also depends on people using the system correctly.

Train staff on:

• startup/shutdown
• safe clearing of jams
• emergency stop use
• lockout/tagout
• what alarms mean
• when not to intervene
• calibration and inspection procedures

Keep training records.

9) Maintain the system

Scheduled maintenance should cover:

• gripper wear
• camera cleanliness and recalibration
• fastener checks
• cable integrity
• safety device testing
• software backup and version control
• performance drift monitoring

10) Keep documentation complete

At minimum, maintain:

• risk assessment
• system architecture and wiring diagrams
• software/configuration baselines
• test/validation results
• safety device certifications
• operating manual and SOPs
• training records
• maintenance logs
• incident reports and corrective actions
