Since the tme architecture and construction began embracing robotcs, the pre-fab movement has grown rapidly. As the possibilites for new design and fabrication emerge from creatvity and need, the application and use of new robotc technologies becomes vital. This movement has been largely focused on the deployment of industrial-type robots used in the (automobile) manufacturing industry for decades, as well as trying to apply these technologies into off-site building construction. Beyond the pre-fab (off-site) conditions, on-site fabrication offers a valuable next step to implement new construction methods and reduce human work-related injuries. The main challenge in introducing on-site robotc fabrication/construction is the dificulty in calibrating robot navigation (localization) in an unstructured and constantly changing environment. Additionally, advances in robotc technology, similar to the revolution of at-home 3D printing, shift the ownership of modes of production from large industrial enttes to individuals, allowing for greater levels of design and construction customization. This paper demonstrates a low-cost humanoid robot as highly customizable technology for floor tling. A novel end-effector design to pick up tles was developed, along with a localization system that can be applied to a wide variety of robots.
