Phase 4: Implementing concepts in manufacturing
In conclusion, Fraunhofer also offers a comprehensive range of possibilities for the final realization of the application. Fraunhofer IPA shows what this might look like with three examples.
For example, the pitasc software addresses a common hurdle for assembly automation, namely the diversity of variants, which until now has been associated with high programming costs. These costs quickly make the use of robotics uneconomical. This is where pitasc comes in: with the software, an assembly task no longer has to be programmed point by point. Instead, programming is done in a structured and modular way relative to the workpiece, based on data provided by sensors on the robot. Pre-fabricated, reusable program modules help to implement especially tricky, force-controlled assembly applications faster than before and enable efficient adaptation to new variants. “For example, the position of the robot, the fixtures and even the end effector can be changed without reprogramming”, says Anwar Al Assadi, Group Leader at Fraunhofer IPA, explaining the advantages of the pitasc solution.
A spin-off from Fraunhofer IPA is pursuing a different approach for better planning and execution of an assembly task. The start-up is developing the Assemblio Assembly Suite, artificial intelligence (AI)-based software which analyses and evaluates CAD STEP files. Any CAD system can generate these information-rich files. They provide the “3D analysis AI” with all the necessary information to precisely derive structured assembly information. A second component of Assemblio is the Assembly Composer, which reads the extracted assembly information and feeds it into an assembly planning tool. The tool displays assembly-relevant information in a simplified, graphic format, making assembly amazingly easy and possible to plan without error. The AI assembly assistant KIM provides staff with interactive support in the form of automatic and cost-effective assembly assistance. The assistance is variable and can be either 2D or 3D-based. Alexander Neb, CEO of the spin-off, says: “Initial user studies reveal time savings of up to 92% when using Assemblio.” The software will be commercially available from July of this year.
