In recent years, off-site robotics have been investigated extensively and there are some promising candidates emerging. One such category of robots is exoskeleton robots and this paper provides an in-depth assessment of their suitability in assisting human operators in undertaking manual operations typically found in the construction industry. This work aims to objectively assess the advantages and disadvantages of these two suits and provide recommendations for further improvements of similar system designs. The paper focuses on the passive exoskeleton robotic suits which are commercially available. Three types of activities are designed and a mechatronic methodology has been designed and implemented to capture visual data in order to assess these systems in comparison with normal human operations. The study suggests that these passive suits do reduce the effort required by human operators to undertake the same construction tasks as evidenced by the results from one focused study, though a number of improvements could be made to improve their performance for wider adoption.展开更多

A total of 196 risk sites in Guangxi were collected by means of questionnaire survey,expert evaluation and field survey. The results showed that fire,pest and wind hazards are the main types of risk points in Guangxi. The survey showed that there were 77 monitoring stations around the disaster risk sites belonging to the Forestry Sector,which mainly monitor fire hazards,while other disasters had no monitoring point yet. Early warning facilities were still constantly improving. The meteorological disasters that affecting forestry production were drought,gale,and heavy rainfall,and the main meteorological hazard factors were temperature,wind speed,and precipitation. Forest fire prevention,forestry resources development and utilization,forestation and tending demand for meteorological services were relatively large. It was hoped that forestry meteorological service products would be obtained through telephone,SMS and early warning systems. In addition,experts objectivly evaluated the contribution rate of meteorological services in Guangxi. The contribution rate of forest meteorological services in the whole region was8. 41%. The scale of Guangxi's total forestry output value was 31. 478 billion yuan in 2016. According to the calculation of this value,the service benefit value had reached 2. 647 billion yuan. In conclusion,strengthening the cooperation in forestry meteorological monitoring,technology development,and emergency response,and further improving forestry meteorological services and effective reducing forestry disaster losses are the top priorities of the meteorological department.展开更多
