The UK Scheme is available to all companies (not sole traders) registered in England & Wales, Scotland or Northern Ireland involved in industrial robot integration. Interested companies are required to complete a free self-assessment to check whether they meet the necessary criteria prior to applying to be independently audited by an authorised RIA / BARA assessor.
All companies can complete a free self-assessment to check their eligibility under the RIA / BARA Robot Integrators’ Certification Scheme. To proceed to formal audit, the applicant will be required to pay the registration fee (payable to: PPMA Limited) and the audit fee (payable to assigned RIA / BARA auditor in advance of audit) in full. Go to Certification Scheme Costs.
What is the process for re-certification under the RIA / BARA Robot Integrators’ Certification Scheme?
All companies certified under the RIA / BARA Robot Integrators’ Certification Scheme are required to be re-audited every two years. The RIA / BARA UK Scheme auditor will notify all certified companies prior to the end of the certification period.
Companies must complete and return the ‘Biennial Integrator Re-certification Assessment Form’ to the auditor before the end of the two-year certification period. This includes the cost for re-certification.
Re-certification requires the certified robot integrator to complete a new self-assessment. This enables the auditor to establish whether there have been any major changes since the previous certification audit.
Should the re-certification period elapse without satisfying the payment terms of assessment form requirement, the applicant company will be treated as a new integrator and will again need to meet the cost of a first audit. No registration fee will apply if previously paid.
Cost(s) for re-certification is available here.
Once certified under the RIA / BARA Robot Integrators’ Certification Scheme (“UK Scheme”), companies will be authorised to display the official RIA / BARA certified robot integrator logo on their business stationery and company website for the two-year certification period.
Use of the logo, which is available through the UK Scheme administrator, remains the dual copyright of the Robotic Industries Association (RIA) and the British Automation and Robot Association (BARA).
A list of RIA / BARA certified robot integrators are also published on the BARA website here.
It is a prerequisite for integrators to conduct a risk assessment (as per ISO 10218-2) to satisfy the criteria to become a Certified Robot Integrator (see Question 8 on the Self Assessment scorecard).
An integrator will score ‘five marks’ if they conduct the robot risk assessment on a customer’s system in conjunction with the customer, and ‘four marks’ if the integrator undertakes the risk assessment by him/herself with no consultation with the customer.
A risk assessment shall take into effect all the tasks and hazards associated with the robot system, which in return produces the safest robot system. Integrators can then publish the following statement in the system instruction manual(s) / book(s): “A robot risk assessment has been conducted on this system to ensure the safety of those associated with using it.”
Laser profiling using triangulation is one of the most popular 3D techniques. The object to be measured passes through a line of laser light and a camera mounted at a known angle to the laser records the resulting changing profile of the laser line. These 3D profiles deliver high measurement resolution with good measurement range. They produce a point cloud that when projected onto a designated plane creates a depth map that is conveniently analysed using well-known 2D vision tools like blob analysis, pattern recognition and optical character recognition. This technique relies on the object moving relative to the laser line so this configuration is particularly popular on production and packing lines where the product moves on a conveyor. The system can be configured using individual laser sources and cameras, or integrated systems where the source and camera are housed in a single enclosure. Care must be taken to avoid shadowing, where higher regions of the object block the view of the laser line so that data from the structures behind cannot be obtained. One solution is the use of several cameras which track the laser line from different angles and then merge the different data sets to a single height profile using sophisticated software tools.
Another common 3D method mimics nature by using a binocular stereo set-up where two cameras are used to record 2D images of an object. A 3D image can then be calculated using triangulation. This technology also allows for movement of the objects to be measured during recording. A random static illumination pattern can be used to add arbitrary texture to plain surfaces and objects that do not have the natural edges (texture) information which the stereo reconstruction algorithms require. This technology has proved very successful in applications such as volumetric measurements and robot bin-picking. Some systems are available which utilise line scan cameras instead of area scan cameras and are particularly useful for fast moving objects or web applications. Photometric stereo uses a number of images to reconstruct the object surface. Here a single camera and the object are fixed, while the scene is illuminated from different known orientations taken in consecutive images. This method gives only relative height measurements, making it an excellent choice for 3D surface inspection.
Light stripe projection requires static objects. Here, the whole surface of the sample is acquired at once by projecting a stripe pattern to the surface, typically at an angle of 30˚ and recording the resulting image with a camera perpendicular to the surface. The large number of points acquired simultaneously gives height resolution up to two orders of magnitude better than with laser profiling. The measuring area can be scaled from less than a millimetre up to more that one metre so suits small as well as large samples.
Time of flight
Time of flight cameras measure the time taken for a light pulse to reach the object and return for each image point. Since the time is directly proportion
