A novel localization algorithm with low-cost sensors for cleaning robots is presented in this paper, which includes fusing the data of encoders and an electronic compass to estimate the posture state of the robot by using Kalman filter. It judges the confidence of the data of the electronic compass with magnetic field intensity; judges the confidence of data of odometer by the information of slippage...
A novel calibration approach to determine the coordinate transformation between the robot tool and the external axle worktable based on differential evolution algorithm is presented. The methodology can be divided into three different steps. Firstly, the transformation relationship between the robot wrist and the contact position sensor tool is calibrated. Secondly, the transformation relationship...
This paper presents an efficient method for rigid registration of 3-D point sets, which intends to match the feature points inspected by armed inspection robots with the points on designed CAD surface. The alignment error is defined as the least square problem, and the sphere radius of the inspection probe is considered. In this framework, the matching problem is converted into acquiring six Euler...
The BLISK (blade integrated disk) is a new structural component of the modern aero-engine and plays an important role in improving its performance. However, it's very difficult to measure the BLISK because of its complicated shape. A novel method for measuring BLISK online is introduced in this paper. An industry robot, an electronic lever indicator and a revolving table are used to measure the BLISK...
A novel robot system for large size in-pipe surface inspection is presented. The proposed system is suitable to the large size pipes with diameter from Phi580 mm to Phi1000 mm. The accuracy of the system is so high that the measurement error is within 5/1000 millimeter. The equipment initialization can be implemented automatically for various objects with different sizes due to its intelligent design...
