Post-construction quality assessment is an integrated part of any construction project which plays a vital role for the entire project. Existing repetitive, labor intensive and less productive manual inspection methods make the construction quality assessment automation a necessary research topic. In contrast to the manual inspection methods, recent advances in robotic technologies and low cost sensors...
This paper proposes a permanent magnet spherical actuator (PMSA) with three-dimensional magnet array. The application of 3D magnet array improves the output torque significantly. However, as PMSA is a multivariable and nonlinear system, it is very complicate to achieve high accuracy control. Therefore, a novel single neural adaptive control algorithm is proposed in this paper. Compared with the PD...
Industrial robot arm has been used in a lot of applications, but most of them require manual teaching from the operator, or careful path-planning by experienced programmer. Offline programming is one of the solution for more sophisticated applications, but the 3D model of the workpiece should be provided, especially for applications such as painting, thermal spraying, etc. With the increasing availability...
