Trajectory-Based Skill Learning for Overhead Construction Robots Using Generalized Cylinders with Orientation

Overhead work involving the construction and maintenance of civil infrastructure (e.g., tunnels, overpasses, and buildings) is strenuous and fatigue-inducing for human workers and is particularly well-suited for co-robotization. Such work is …

Interactive and immersive process-level digital twin for collaborative human–robot construction work

Human cognition plays a critical role in construction work, particularly in the context of high-level task planning and in-field improvisation. On the other hand, robots are adept at performing numerical computation and repetitive physical tasks with …

Human–robot collaboration in construction: classification and research trends

Construction robots continue to be increasingly deployed on construction sites to assist human workers in various tasks to improve safety, efficiency, and productivity. Due to the recent and ongoing growth in robot capabilities and functionalities, …

Teaching robots to perform quasi-repetitive construction tasks through human demonstration

Robots can assist workers in performing physically-demanding construction tasks, which are typically quasi-repetitive, wherein the geometry of the workspace is dissimilar despite similar tasks. As a result, robots must determine motion trajectories …

Enhancing stroke assessment simulation experience in clinical training using augmented reality

The development of extended reality in recent years is opening doors for using extended reality devices (virtual reality, augmented, and mixed reality devices) in education and healthcare. The purpose of this pilot study was to test the use of …

A vision-based marker-less pose estimation system for articulated construction robots

The prospect of human-robot collaborative work on construction sites introduces new workplace hazards that must be mitigated to ensure safety. Human workers working on tasks alongside construction robots must perceive the interaction to be safe in …

A virtual reality tool for training in global engineering collaboration

Global collaboration is the major trend in the architecture, engineering, and construction industry; training in global engineering collaboration thus is highly demanded in existing engineering education. One approach to this training is to expose …

RAS: a robotic assembly system for steel structure erection and assembly

This research focuses on a long-standing, yet critical problem in the erection of steel structures. In the current state of practice, steel workers must stand on an unfinished structure to assist with the assembly of structural elements manually. …

Strategies to accelerate the computation of erection paths for construction cranes

The current crane erection path computation methods are not easily scalable for assisting engineers to find and evaluate detailed erection plans. A reliable and efficient method to help plan erection paths is required, especially for certain critical …
