Hi, I'm Dillan, Partner and Automation Engineer at Kurtin Robotics Company. As an expert in robotics integration, I've overseen numerous successful projects and learned what works best in robotic cell design. Here are four easy steps to enhance your robotic cell designs using CAD, based on our experience at Kurtin Robotics Company.
1. Put the Entire System in CAD
Enhanced Visualization
Creating detailed 3D models in CAD helps visualize the final product, allowing for better understanding and decision-making. Every nut and bolt counts because you never know when two things will interfere when you go to build it. By seeing the whole system, potential issues can be identified early, reducing costly revisions.
Improved Accuracy
CAD ensures precise modeling of components, which is crucial for seamless part integration and functionality. You can use the X, Y, and Z measurements in CAD to get the dimensions for the TCP (Tool Center Point) of the tool you are making. Simulating various scenarios in CAD helps predict and mitigate potential problems.
Streamlined Collaboration
CAD models serve as a universal language among team members, enhancing communication and efficiency. Sharing detailed models ensures everyone is on the same page, reducing misunderstandings.
Efficient Documentation
CAD software generates comprehensive documentation of the design process, aiding future reference, troubleshooting, and maintenance. This ensures consistency and quality throughout the project.
2. Use Joints in CAD for Accurate Motion
Realistic Motion Simulation
Defining joints in CAD models allows for realistic simulation of robotic movements. This verifies the design’s functionality and ensures the robot performs tasks effectively.
Identify Motion Issues
Simulating motion helps detect potential issues like collisions, robot reach limits, and singularities early, minimizing unexpected problems during implementation. It also helps in determining where things will go in the workspace.
Enhance Design Robustness
Utilizing joints in CAD enhances the robustness of the design by ensuring that the robot can navigate its workspace efficiently and without encountering obstacles or constraints that could hinder its performance.
3. Utilize Datums for Consistency
Reliable Reference Framework
Datums provide fixed reference points, lines, or planes, ensuring accurate positioning and alignment of components. This maintains consistency and precision throughout the design process.
Simplify Complex Geometries
Using datums simplifies the modeling of complex geometries, making it easier to manage and modify the design. This leads to more efficient and error-free designs.
4. Designing in Multiple Smaller Parts
Manageable Components
Breaking down the design into smaller, manageable parts simplifies the manufacturing process. It’s easier to produce, assemble, and test smaller components than a single complex structure.
Flexibility and Modularity
Designing in parts allows for greater flexibility and modularity. Parts can be easily replaced or upgraded without affecting the entire system, enhancing maintainability and scalability.
Cost-Effective Production
Smaller components are often cheaper to produce and assemble, reducing overall production costs. This approach also minimizes waste and enhances resource efficiency.
I hope this helps you improve your robotic cell designs and achieve better outcomes!
