“…Apart from space programs, autonomous bulldozers have been developed for surveillance, mining and construction. In [73], Moteki et al have adapted the unmanned construction system technology to build semiautonomous bulldozers for operation against of a disaster occasion. Most recently, ASI Robotics Inc. has developed a system of robotic hardware components that allow users to control a vehicle in both modes, manual and autonomous.…”

Amongst increasing innovations in frontier engineering sciences, the advancements in Robotic and Autonomous Systems (RAS) has brought about a new horizon in construction applications. There is evidence of increasing interest in RAS technologies in the civil construction sector being reflected in construction efforts of many military forces. In particular, Army or ground-based military forces are frequently called upon to conduct construction tasks as part of military operations, tasks which could be partially or fully aided by the employment of RAS technologies. Along with recent advances in the Internet of Things (IoT) and cyberphysical system infrastructure, it is essential to examine the current technical feasibility, maturity, affordability, as well as the challenges and future directions of the adoption and application of RAS to military construction. This paper presents a comprehensive survey and provides a contemporary and industry-independent overview on the state-ofthe-art of construction automation used in defence, spanning current world's best practice through to that which is predicted over the coming years.

“…This is because these views are similar to those that operators watch when they operate heavy machinery and cab views during teleoperation. Moreover, operators prefer watching cab views from cameras in heavy equipment, rather than views from cameras around the work site (Moteki, Fujino, Ohtsuki, & Hashimoto, 2011). This planning can help operators keep working without stops, speed of the attachment can be faster during grasping, and moving distance can be decreased as explained in Subsection 2.2.2.…”

One of the most important problems in teleoperation of heavy machinery is that the work efficiency of teleoperation is lower than half that of a typical boarding operation. This difference is primarily caused by operators' difficulty in creating mental representations (i.e., cognitive maps) of work sites. Operators have two opportunities to acquire information, namely before work and during work, because the introduction of teleoperation requires about one week. Therefore, we have developed a view system to be used before work to provide environmental information concerning work sites on the basis of human spatial cognition. Cognitive maps can be built by acquiring knowledge from two perspectives—the survey perspective and the route perspective. We display an external view from any viewpoint to acquire knowledge from a survey perspective and a view from an operator's viewpoint, which can be modified by the operator's intention to acquire knowledge from the route perspective. Experimental results using a simulator suggested that a proposed view system could help operators acquire cognitive maps, which may lead to a decrease in task time, the number of stops, and the moving distance and an increase in speed during grasping.

“…This occurs because some target work objects are occluded by the robot ann in the camera image. Mounting multiple cameras is an effective technique to improve operating efficiency [4], [5]. Using multiple cameras enables to the operator to confirm the position and shape of the target work objects, because dead spaces that the operator carmot see are decreased.…”

This paper presents a method to compose half diminished reality images for remote control robots using three RGB-D sensors. Robots are designed to perform the work of humans during a disaster response to reduce secondary disasters.In these case, a operator controls the robot with the aid of images from a mounted camera. However, operating efficiency decreases significantly when the robot arm occludes target work objects in those images. Recently, the Half-Diminished Reality technique has been proposed in the field of computer vision.This teclmique is used for seeing through foreground objects and viewing occluded backgrOlmds. Accordingly, composing half diminished reality images can enable the operator to see the target work objects occluded by the robot arm in only one image, which results in increased the operating efficiency.
