How SP Automation & Robotics Conducts Proof of Principle Work

February 2025

At SP Automation & Robotics, Proof of Principle (PoP validation) is a structured process that ensures every project starts on a solid foundation. Our approach includes:

Identifying Key Risks and Critical Components

Before conducting PoP work, we assess the project’s most technically challenging or high-risk areas. This could involve:

• Complex mechanical movements.
• Custom end-of-arm tooling.
• High-speed material handling.
• Advanced vision and inspection systems.

Developing Targeted PoP Tests

Rather than building a full prototype, we focus on the specific function that requires validation. This could include:

• 3D printing a custom gripper to test its ability to handle delicate components.
• Setting up a vision system to assess its ability to detect defects at high speeds.
• Simulating a robotic assembly process to ensure precision and repeatability.

Conducting Real-World Testing

Our PoP studies are performed in conditions that closely replicate the actual operating environment. This helps us evaluate performance under realistic constraints and gather meaningful data on system capabilities.

SP Automation & Robotics Commitment to Investing In POP & R&D

SP has made significant investments in developing its own in-house POP Machine, in addition to exploring bespoke POP and risk reduction solutions. This system is built on the Beckhoff XPlanar transport system, enabling a highly configurable approach to process development. By leveraging the flexibility of XPlanar, our engineers can utilize it for:

• Production motion monitoring, particularly in applications involving fluid movement during transportation. This is especially critical in industries like contact lens manufacturing, where acceleration and deceleration can affect liquid stability.
• Optimizing machine operations and sequencing to enhance efficiency.
• Rapidly adding stations to the machine for tooling development.
• Seamlessly integrating new equipment, ensuring compatibility with existing communication protocols.

The possibilities are virtually limitless, making our POP Machine a powerful tool for innovation and efficiency. This investment allows SP to ensure we can reduce our customer’s risks and remove “guesswork”.

Refining the Design Based on Findings

If a PoP test identifies a weakness in the design, we use this insight to make adjustments before moving forward. This iterative approach ensures that by the time we progress to full-scale production, the system is proven, optimised, and ready for seamless deployment.

Case Study: PoP in Action

Challenge:

A client required an automation solution to pick and place delicate glass components with sub-millimeter precision. The challenge was ensuring the robotic gripper could handle the components without causing damage or misalignment.

PoP Approach:

We designed a Proof of Principle test using a prototype gripper and real components. The test evaluated:

• Gripping force and its effect on the glass.
• Accuracy of pick-and-place movements.
• Ability to adjust for slight variations in component positioning.

Outcome:

The initial design revealed minor inconsistencies in grip force, which were corrected through material and sensor adjustments. PoP testing resolved the issue before building the final system, saving time and money and preventing potential production delays.

Conclusion: The Value of Proof of Principle in Automation

Proof of Principle is an essential tool in de-risking automation projects. By validating critical functions early, it provides technical assurance, cost savings, and increased confidence in the final solution.

At SP Automation & Robotics, we integrate PoP into our process to ensure every automation system is tailored, reliable, and optimised for success. By investing in early-stage validation, we help our clients achieve seamless, high-performance automation solutions that deliver long-term value.
