Redesign a Manufacturing Workstation for Human-Robot

Updated 14 November 2026 · Standard formula, shown below

This guide walks you through redesigning an existing manufacturing workstation so a human and a robot can work together safely and productively. You’ll learn how to assess the current layout, define the robot’s tasks, plan for safety, and implement the change step by step. Before you start, you need a clear understanding of the current process, the tasks you want to automate, and any applicable safety standards in your region (such as ISO/TS 15066 for collaborative robots).

What You’ll Need

Current workstation layout drawings or a detailed sketch
Task analysis data (cycle times, motions, ergonomic pain points)
Robot specifications (reach, payload, speed, safety features)
Safety equipment: light curtains, laser scanners, pressure-sensitive mats, or force-limiting software (as needed)
Hand tools for reconfiguring (wrenches, screwdrivers, etc.)
Personal protective equipment (PPE) for the team
Time and budget for testing and iteration

Step-by-Step

Document the current process. Record every step a human performs, including part handling, tool use, and quality checks. Note cycle times for each step and identify any steps that are repetitive, ergonomically stressful, or dangerous.
Decide which tasks to automate. Choose tasks that are repetitive, require high precision, or involve heavy lifting. Keep tasks that need human judgment, fine motor skills, or flexibility for the human. For example, the robot might load parts into a machine, while the human does final inspection.
Assess the robot’s capabilities. Check the robot’s reach, payload, speed, and safety features. Determine if it needs additional sensors or tooling (grippers, vision systems) to perform the chosen tasks.
Design the new layout. Sketch a layout where the robot and human share space but have clear zones. The robot should have a dedicated area for its motions, and the human should have a clear path to their work area. Ensure the robot’s reach covers its tasks without intruding into the human’s walking paths.
Plan for safety. Implement safety measures based on the risk assessment. For a collaborative robot, this might include force and speed limiting, safety-rated monitored stops, or hand-guiding mode. For more hazardous operations, use physical barriers or safety zones with light curtains.
Set up the robot. Mount the robot securely and install any end-of-arm tooling. Program the robot’s motions for the assigned tasks, using slow speeds initially. Test the robot’s movements in a safe mode before allowing human interaction.
Integrate the human tasks. Rearrange the human’s work area so they can comfortably perform their remaining tasks. Provide adjustable workstations (if possible) and ensure all tools and parts are within easy reach. Make sure the human can easily see the robot’s status (e.g., running, paused, error).
Test the combined workflow. Run the robot and human through the new process together, starting with a dry run (no parts) to check for collisions or timing issues. Then run with parts, observing cycle times and any bottlenecks.
Train the team. Provide thorough training on the new system: how to operate the robot, what to do in an emergency, and how to interact safely. Emphasize that the robot is a tool, not a replacement, and that their role is still vital.
Monitor and refine. After implementation, track performance metrics like cycle time, error rates, and worker fatigue. Use this data to make adjustments—maybe the robot needs a different gripper, or the human’s station needs better lighting.

Common Mistakes

Skipping the risk assessment. Every robot installation requires a risk assessment. Failing to do one can lead to serious injuries and legal issues.
Over-automating. Trying to automate tasks that require human judgment often leads to costly failures. Keep the human in the loop where they add value.
Ignoring the human’s ergonomics. If the human’s new tasks are awkward or strenuous, they’ll be less productive and more likely to get injured. Design the human station with the same care as the robot’s.
Not planning for maintenance. The robot needs regular maintenance. Ensure there’s easy access for technicians and that maintenance doesn’t disrupt the human’s workflow.
Forgetting about communication. The human needs to know what the robot is doing. Use clear visual indicators (lights, screens) and audible signals to keep the human informed.

Tips

Start small. If possible, pilot the new workstation with one robot and one human before rolling out to other lines.
Involve the workers early. Get input from the people who will actually use the workstation. They often have practical insights that engineers miss.
Use simulation software. Before physical changes, simulate the robot’s motions and the human’s interactions in a 3D environment to catch potential issues.
Make the robot’s motions predictable. Program paths that are smooth and repeatable, so the human can anticipate where the robot will be.
Keep the human’s work area uncluttered. A clean, organized station reduces the risk of accidents and improves efficiency.

Troubleshooting

The robot stops unexpectedly. Check safety sensors (light curtains, pressure mats) for false triggers. Ensure the robot’s safety zone isn’t being violated by the human’s normal movements.
Cycle times are slower than expected. Look for bottlenecks—maybe the robot waits for the human, or the human waits for the robot. Adjust the sequence or add buffers (e.g., a small queue of parts).
The human feels uncomfortable or unsafe. Stop the process and review the safety measures. Increase the safety distance, reduce robot speed, or add more guarding. Never ignore a worker’s concern.
The robot can’t reach a part. Recheck the robot’s reach and the part’s position. You may need to move the part or add a conveyor to bring it closer.
Quality issues appear. The robot may be handling parts too aggressively. Adjust the gripper force or the robot’s acceleration. Also check that the human’s inspection steps are still effective.

Frequently Asked Questions

What is the difference between a collaborative robot and a traditional industrial robot?

A collaborative robot (cobot) is designed to work safely alongside humans, with features like force limiting and speed monitoring. A traditional industrial robot is usually faster and stronger but must be separated from humans by guards or fences.

Do I need a safety fence?

It depends on the risk assessment. If the robot operates at low speed and force, and has collaborative features, you might not need a fence. But if the robot can cause injury, you must use physical barriers or safety-rated devices like light curtains.

How fast can a collaborative robot move?

Speed limits are set by safety standards, typically up to 250 mm/s (about 10 inches per second) for the robot’s end effector when in collaborative mode. However, this can vary based on the robot model and the risk assessment.

Can the robot and human work on the same task simultaneously?

Yes, that’s the goal of a collaborative workstation. For example, the robot might hold a part while the human screws in bolts, or the robot might do the heavy lifting while the human does the fine assembly.

What training do workers need?

Workers need training on the robot’s operation, safety features, emergency stop procedures, and how to interact with the robot. They should also understand the overall workflow and their role in it.

How long does it take to redesign a workstation?

It varies widely—from a few days for a simple setup to several months for complex installations. The key is to plan thoroughly and allow time for testing and refinement.
