“…The area is mapped in purple in the visualised networks shown in Figure 5. Capitani et al (2021) designed an exoskeleton for construction workers that follows the specifications provided by an applicant in a model-based mechanical design of a passive lower-limb exoskeleton for assisting workers in shotcrete projection. The safety aspects in integrating robots with humans on site and what it portends for human factors were advanced by Boon et al (2021) in safety enablers using emerging technologies in construction projects with Malaysia as a case study.…”

Purpose Rapid urbanisation and recent shock events have reiterated the need for resilient infrastructure, as seen in the pandemic. Yet, knowledge gaps in construction robotics and human–robot teams (HRTs) research limit maximising these emerging technologies’ potentials. This paper aims to review the state of the art of research in this area to identify future research directions in HRTs able to aid the resilience and responsiveness of the architecture, engineering and construction (AEC) sector. Design/methodology/approach A total of 71 peer-reviewed journal articles centred on robotics and HRTs were reviewed through a quantitative approach using scientometric techniques using Gephi and VOSviewer. Research focus deductions were made through bibliometric analysis and co-occurrence analysis of reviewed publications. Findings This study revealed sparse and small research output in this area, indicating immense research potential. Existing clusters signifying the need for further studies are on automation in construction, human–robot teaming, safety in robotics and robotic designs. Key publication outlets and construction robotics contribution towards the built environment’s resilience are discussed. Practical implications The identified gaps in the thematic areas illustrate priorities for future research focus. It raises awareness on human factors in collaborative robots and potential design needs for construction resilience. Originality/value Rapid urbanisation and recent shock events have reiterated the need for resilient infrastructure, as seen in the pandemic. Yet, knowledge gaps in construction robotics and HRTs research limit maximising these emerging technologies’ potentials.

Musculoskeletal disorders are often found in various types of work, including surgeons. Standing working position is immobile and rigid when performing surgical operations. The equipment used is less ergonomic which is the main parameter. The surgeon profession belongs to the category of the high-risk profession and has the potential to experience musculoskeletal disorders. Surgeons who suffer musculoskeletal disorders sense disease start from mild-to-severe due to the muscles receiving static loads frequently in the long-term. The emergence of musculoskeletal disorders can be caused by working environment conditions and standing position while working, causing injury to joints, vertebral discs, nerves, cartilage, tendons, and muscles. This paper describes in extensive the potential for reducing musculoskeletal problems with the use of a chairless chair for surgeons in carrying out operations. Musculoskeletal problems in surgery and the use of chairless chairs have been further explored to close the existing research gap.

“…As opposed to an active exoskeleton, passive exoskeletons have been put into practice successfully in different scenarios [29,30]. Given the assistant method of the passive exoskeleton, the elastic element has been used to assist human movement through combining the characteristics of human movement [31].…”

A Compatible Design of a Passive Exoskeleton to Reduce the Body–Exoskeleton Interaction Force

et al. 2022

In the research and development of a passive exoskeleton, the body–exoskeleton coupling mode is a key point to reduce the interaction force and realize the efficient assistance of the exoskeleton. The purpose of this paper was to explore a cooperative movement mode between human and passive exoskeleton for reducing the body–exoskeleton interaction force. Firstly, through the research of the body–exoskeleton interactive mode, we analyzed the kinematic and dynamic constraint of the exoskeleton and established a dynamic model of the body–exoskeleton system. On this basis, the characteristic of the body–exoskeleton interaction force was analyzed; then, we put forward a mode that uses human gravity and load weight to maintain the stability of the exoskeleton’s movement to achieve the goal of reducing the interaction force. Based on the human–exoskeleton integrated mode, we constructed a mechanical model and simulated the change in interaction force in this mode; the simulation results showed that the interaction force at the lower leg was 98.5% less than that of the pure mechanical exoskeleton. Finally, we developed a prototype that was made of plastic parts and finished the experiment by walking with a load of 30 kg. The experimental results showed that this mode reduced the body–exoskeleton interaction force by 65.1%, which verified the effectiveness of the body–exoskeleton coupling mode preliminarily. The research results provided a new analytical approach for the design of a passive exoskeleton, and its improvement effect could be extended from the lower leg of the body–exoskeleton to the thigh or trunk, and guide the design of a passive exoskeleton.
