Center node: "bim assisted object recognition for the on site autonomous robotic assembly of discrete structures"
  Abstract: Robots-operating autonomous assembly applications in an unstructured environment require precise methods to locate the#R##N#building components on site. However, the current available object detection systems are not well-optimised for construction#R##N#applications, due to the tedious setups incorporated for referencing an object to a system and inability to cope with the elements imperfections. In this paper, we propose a fexible object pose estimation framework to enable robots to autonomously#R##N#handle building components on-site with an error tolerance to build a specifc design target without the need to sort or label#R##N#them. We implemented an object recognition approach that uses the virtual representation model of all the objects found in#R##N#a BIM model to autonomously search for the best-matched objects in a scene. The design layout is used to guide the robot#R##N#to grasp and manipulate the found elements to build the desired structure. We verify our proposed framework by testing it#R##N#in an automatic discrete wall assembly workfow. Although the precision is not as expected, we analyse the possible reasons#R##N#that might cause this imprecision, which paves the path for future improvements.
