Sensor device for intuitively manipulating the heavy material-handling robot
As the conditions of working environment at the construction site cannot be typified, intelligence of robot system is considered to be the best solution for a lack of uniformity and homogeneity such as various kinds of unexpected situations or conditions. Precise finishing quality of robot system, pre-fabrication system of construction materials, and undisturbed material circulation system also remains unsolved problems, up to now. Human-robot cooperation technology based applications have been come up for several decades to combine the human's advanced neural system with robot's enhanced physical performance. This study proposes the newly-designed sensor device for intuitively manipulating the heavy material-handling robot system through the analysis of conventional method. And the feasibility of virtual coordinate generation algorithm and performance evaluation of the proposed system is verified through the experiments and field-test.
Design of a Ceiling Glass Installation Robot
Building materials and components are much larger and heavier than many industrial materials. Ceiling glass is a type of building material for interior finishing. The demand for larger ceiling glass has increased along with the number of high-rise buildings and an increased interest in interior design. The objective of the study is to introduce robotic technology for installing ceiling glass on construction site. Robotically installed ceiling glass is receiving special attention because of the difficulties in moving to high installation positions and handling fragile building materials. Below, we describe the design of a ceiling glass installation robot. After analyzing a target project, we establish a design concept for a proposed robot. Finally, we describe the detailed design of the robot.
