A new type of bolting robot for steel-frame structure constructions

Abstract

In this paper, a new type bolting robot in steel-frame structure is introduced. The robot is composed of 3-axis gantry arms with linear motion actuators, a bolting tool, a cabin and additional supporting parts. To construct a high-rise building, steel-frame structure is more suitable than reinforced concrete structures. In steel-frame constructions, it is demanded fasten bolts to join two beams. By using this bolting robot, it can improve the efficiency and safety of construction. This paper describes design of a new type bolting robot and its dynamical analysis with some experiments.
