Key techniques of robot for work of drainpipe deposit cleaning
According to the requirement of automatization of drainpipe deposit cleaning work in the municipal engineering works,a kind of robot for drainpipe deposit cleaning work has been researched and manufactured with the simulation analysis and the technique of virtual prototyping.In this paper,the composition principle and key techniques of the robot are elaborated in detail,including the technique of adapting and adjusting the change of pipe diameter,technique of obstacle crossing,technique of walking and driving and so on.The manufactured prototype and results of tests show that the robot possesses characteristics,such as adapting range of pipe diameter between 400 and 500 mm,the walk speed with 2 m /min,the drag force beyond 3 kN,and the walk distance with 1 km.
By Tony Martini, Economics ::: Advisor: Michael Jones ::: Presentation ID: AM_D39 ::: Abstract: This study suggests new methods of measuring the effectiveness of universities in protecting students from the impact of automation on the labor market. Using US government data on occupational activities and traditional measures of university outcomes, we produce a ranking of college majors by their susceptibility to automation and determine correlations between predicted traditional and automation-based outcomes. These are combined into a complete metric for the "automation resistance" of a university. Using an approach centered on distinctly human skills, occupational activities can be ranked by their automation resistance. Institutions which develop student skills with a focus on automation resistance should likewise demonstrate greater long-term viability. We demonstrate this methodology through a case study using data from the University of Cincinnati.
