For thousands of years, the human construction process was mainly done by hand. In an era when automation technology is so mature, although some components of building components can be produced industrially, on-site construction and special component production still require a lot of manpower. But no matter how skilled the workers are, more or less mistakes will occur during the construction process, which wastes a lot of material waste and energy waste, especially when dealing with increasingly complex digital designs. Using a robot instead of manually completing the construction process will be the solution to these problems. Currently, most ideas for robot construction are dealing with non-standard components in the field, this will cause a lot of problems, first of all, it will extend the construction cycle, and secondly, it will generate a lot of waste. This article proposes a new construction workflow using standardized timbers. Spatial information for each piece of wood is communicated directly to a robot fabricator. The robot, equipped with various tools, can accurately position and assemble timbers. This workflow has the potential to improve the sustainability, time, cost, and quality of construction.
