The objective of the project was to construct a model car - using additive technology - which is connected to a phone via cordless communication. PLA was used as a material to print the units. The total weight of the model car is 690 grams including the electronic components. The power consumption and driving properties were measured under given circumstances. Based on our calculations, even in active use at its maximum speed of 5.16 km/h, the system is capable of at least 3.9 hours of operation, while full charging takes only 3 hours. As a result, with two battery units it can be operated continuously.
The inspection of welded structures requires particular attention due to many aspects that define the quality of the product. Deciding on the suitability of welds is a complex process. This work aims to propose a method that can support this qualification. This paper presents a state-of-the-art data-driven evaluation method and its application in the quality assessment of welds. Image processing and CAD modelling software was applied to generate a reference using the Iterative Closest Point algorithm that can be used to generate datasets which represent the model errors. The results demonstrate that the distribution of these variables characterises the typical welding defects. Based on the automated analysis of these distributions, it is possible to reduce the turnaround time of testing, thereby improving the productivity of welding processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
