From LiDAR Cloud Points to Robotic Cell Plan
Cloud Points Not Completed Robotic Project
Spatial data can be very useful without a plan being completed. In the LiDAR procurement, the most important thing is to know at which stage you will use the result. The installation inspection, vehicle construction and motion simulation require different data and different work volumes.
The cloud of points describes the positions of the surface covered. However, the CAD model may consist of certain panels, bodies and structural elements which are further regulated by the designer. Conversion or reconstruction is not just a change in the file extension. The agreement therefore distinguishes the capture, processing and production of the selected model. [1]
Useful Spatial Reference First
For the first overview of the layout we suggest that you define the elements you want to compare with the planned equipment. These may be the external surfaces of the machine, the position of the pillar, the height of the transporter or the access area. Also determine what cannot be reliably understood in the capture.
The presentation of Autodesk University on packing line planning describes the use of scans in linking plans to existing situations and early detection of spatial conflicts. [2] Such use is a good reason for deliberate capture. However, it does not mean that without further assessment we can correct all errors or confirm the entire robotic cell.
For discussion between the customer and the integrator we propose a uniform marking of the parts of the line. The same machine should bear the same mark on the sketch, photographs, spatial inspection and a list of questions. This makes it easier to follow decisions and distinguish the confirmed situation from the proposal.
Select the required modelling level
| Score | Purpose | Pre-order arrangement |
|---|---|---|
| Point Cloud | Reference of visual surfaces covered. | Scope, processing, units and file format. |
| Simplified geometric shapes | Overview of significant spatial constraints. | Which elements are simplified and what should remain identifiable. |
| Editing CAD model | Further construction work according to specific requirements. | Model structure, dimensions, details and verification. |
| Robot cell simulation | Verification of the selected properties of the proposed solution. | Robot, tool, piece, process data and responsibility for verification. |
It doesn't always make sense to model every screw. We suggest that you focus the scope on the elements that influence the decision. When ordering the construction of a corresponding part, clearly specify which surfaces and dimensions must be checked in detail.
Coordinates, units and versions
Before surrender, arrange how the space is oriented and in which units the data are recorded. We propose a description of the starting point and at least some identifiable reference points. In the absence of such an agreement, two properly prepared files in the system may be in the wrong place.
- Project code, capture date and description of the area.
- Units, starting point and agreed orientation.
- List of transferred files and their interconnections.
- Marked missing or questionable areas.
- Description of processing carried out and of the controls agreed.
- The version of the data that the planner may use.
Check compatibility in the target program. Autodesk explains, for example, that the RCP project contains references to RCS files, but not all data in one file. [3] This is the reason why surrender is not sufficiently checked by name list only: the package should also be opened. We do not promise all formats in each order; we coordinate the selected format in advance.
Critical dimensions and verification of solution
We suggest that you classify the dimensions according to purpose. For general layout you need a useful spatial reference. You need properly verified critical dimensions to attach the finished work. For the operation of the robot also model system and process data.
The capture does not replace the safety treatment or cell booting. The demonstration without obvious collision is not an automatic demonstration of adequate access, safe operation or achieved cycle. Before performing, the integrator should define the necessary verification and information that is still needed.
Example of a small production arrangement
Illustration case, not party statement: the company wants to check two possible layouts of the table at the existing machine. For the first decision we propose environmental capture and an agreed simplified presentation of obstacles. Critical fixing positions and table structure are considered separately when the layout is selected.
The expected benefit is less modelling of elements that do not influence the first decision and more attention where precise checks are needed. The cost and usefulness of such an approach should be assessed for a concrete case. In the Council of Blacks we therefore shape the scope according to the desired result, not only to the size of the space.
