“…It is difficult for the above systems to achieve two-dimensional large-angle measurements of more than ±10 • . Therefore, how to achieve a large-scale and high-precision angle measurement has become a research question for many scholars [4][5][6][7][8][9][10][11][12][13][14].…”

In order to solve the problem of the insufficient range of the traditional fast mirror (FSM) angle measurement system in practical applications, a 2D large-angle FSM photoelectric angle measurement system based on the principle of diffuse reflection is proposed. A mathematical model of the angle measurement system is established by combining the physical properties of the diffuse reflecting plate, such as the rotation angle, rotation center, rotation radius, reflection coefficient and the radius of the diffuse reflecting surface. This paper proposes a method that optimizes the degree of nonlinearity based on this mathematical model. The system is designed and tested. The experimental results show that changing the diffuse reflection surface area can improve the nonlinearity of the angle measurement system effectively. When the radius of the diffuse reflection surface is 3.3 mm, the range is ±20°, the non-linearity is 0.74%, and the resolution can reach up to 2.3″. The system’s body is simple and compact. It is also capable of measuring a wider range of angles while linearity is guaranteed.

“…The angular vibration displacement can be measured by detecting the interference signal of the beam diffracted by the two grating surfaces. Bohkman et al 3 proposed an implementation method of dynamic laser goniometer (LG) for non-contact measurement of angular position of objects. At the same time, many experts and scholars have carried out a series of studies on the comprehensive performance of the RV reducer, mainly from the RV reducer transmission accuracy, torsional stiffness, and other aspects.…”

Aiming at the problem of a spur gear fault of the rotation vector (RV) reducer in industrial robots, an instantaneous phase detection technology based on eccentric modulation and laser displacement sensor is proposed. Taking the RV-20E reducer as the object, through the analysis of the RV reducer gear fault mechanism, an RV reducer fault diagnosis test bed is developed to simulate the actual operating conditions of the RV reducer of industrial robot. The instantaneous phase information of the RV reducer is collected, and the adaptive permutation entropy is used to process the instantaneous phase data, which can judge the gear fault type quickly and effectively. The test results show that the fault diagnosis test bench based on this detection technology can effectively and quantitatively judge the fault type of the spur gear of the RV reducer. © The Authors.
