“…In an article prepared for presentation at the "Symposium on Innovation in Computer Technology for the Building Industry" held in October of 1986, Kenneth Reinschmidt [2] of Stone and Webster Engineering Corporation in Boston discusses several aspects of the construction environment , which represent important constraints to the implementation of automation. The first of these characteristics addresses the open versus the closed loop nature of automation.…”

“…This means that the robot is pre-programmed to execute a given routine in space, with little or no sensory feedback... Consequently, many industrial robots are dependent upon human workers to close the loop and to make sure that the work piece is in the proper position for the robot to operate on it. In automated factories the loop is closed by the assembly line itself, which must bring the part to the robots in exactly the position and in exactly the orientation that the robots expect" [2].…”

This paper examines issues which relate to the feasibility of using robotics in the construction industry. Major factors which will influence when and how robotic concepts and machines are implemented in support of the production process in construction are considered. The primary factors driving the adoption of robotics in construction are identified as need, technological feasibility, and the economics of implementation.

Robotics application to the execution of construction tasks has been attracting attention in the engineering community since early 1980's, both in Japan and in other highly industrialized nations. First working prototypes of construction robots have been appearing in Japan on a number of construction sites operated by several leading Japanese construction firms. This paper outlines a research project focused on the planning and management aspects of the use of robotic equipment in construction tasks. This project concentrates on four system modules: Construction Task Analysis Module (CTAM); Robot Capability Analysis Module (RCAM); Robot Economics Evaluation Module (REEM); and Robot Implementation Logistics Module (RILM). This paper briefly describes each of these modules, and presents a summary of results obtained from research completed to date on CTAM.

“…These methods substitute lower-cost machines (e.g., small bulldozers for motor graders) and lower-skilled operators, while improving quality. 11,2] Another earthwork application is the John Deere 690C Teleoperated Remote Controlled Excavator. Fully operable from remote locations, this machine is designed for excavating and handling unexploded ordnance and other hazardous materials such as chemical and nuclear waste.…”

Automation and robotic applications for use in the North American construction industry are currently under development at numerous university and industry laboratories. A number of these applications have been tested under simulated or actual jobsite conditions; some have provided enough information to determine technical success or economic feasibility of the technology. Further development of robotics applications for the construction industry will be achieved by a combination of university research and development and jobsite experimentation in the private and government sectors. EARTHWORK APPLICATIONSExamples of automation and robotic applications on North American jobsites include automated precision guidance systems for construction machinery and remote-controlled devices to inspect or rehabilitate structures. Automated excavation grade control using laser surveying equipment combined with electro-hydraulic feedback control systems mounted on bulldozers, motor graders, scrapers, etc. has been used for civil earthwork applications. In highway grading, large parking lots, and canals , these techniques have reduced costs in some cases by over 80 percent and improved quality (e.g., subgrade thickness tolerances of 2 percent versus 10-20 percent). These methods substitute lower-cost machines (e.g., small bulldozers for motor graders) and lower-skilled operators, while improving quality. 11,2] Another earthwork application is the John Deere 690C Teleoperated Remote Controlled Excavator. Fully operable from remote locations, this machine is designed for excavating and handling unexploded ordnance and other hazardous materials such as chemical and nuclear waste. It is equipped with a high-resolution color video monitor with pinch diagonal screen, speakers, and amplifiers. The camera controls include pan, tilt, zoom, focus, and iris. The excavator has been used successfully at a munitions disposal site in Tennessee and is being evaluated for rapid runway repair functions.t13jOther civil earthwork applications include Miller Formless Co.'s Automated Slipforming Systems and Bulk Cement Unloading Systems.[4] Miller Formless has developed five machines for sidewalk curb and gutter construction that can pour concrete closer to obstacles than other forming equipment. They can be assembled to order for the construction of bridge parapet walls, monolithic sidewalks, curbs and gutters, barrier walls, and other continuously formed elements commonly used in road construction. The machines include proportional control of the grade system by two grade sensors; two amplifiers; two servo valves; and a cross-sloping feature. All of these machines can operate in a 16 playback mode, following a preset path of work. These devices require less labor than conventional methods and are considered economically feasible.[5'Robot Excavator (REX), created by Carnegie-Mellon University (CMU), is another automated earthwork application. REX unearths buried utility piping by sonar-mapping an excavation site, planning the digging operat...
