چکیده

Experimental evaluations for path estimation are performed on an abb irb4600 robot. Di erent observers using Bayesian techniques with di erent estimation models are proposed. The estimated paths are compared to the true path measured by a laser tracking system. There is no signi cant di erence in performance between the six observers. Instead, execution time, model complexities and implementation issues have to be considered when choosing the method.

Estimation of Orientation and Position of an Accelerometer Mounted to an Industrial Manipulator, Report no. LiTH-ISY-R-2995

A method to nd the orientation and position of a three degree-of-freedom (DOF) accelerometer mounted on a six DOF industrial robot is proposed and evaluated on experimental data. The method consists of two consecutive steps, where the rst is to estimate the orientation of the sensor using data from static experiments. In the second step the sensor position relative to the robot base is identi e...

Tool Position Estimation of a Flexible Industrial Robot using Recursive Bayesian Methods, Report no. LiTH-ISY-R-3024

A sensor fusion method for state estimation of a exible industrial robot is presented. By measuring the acceleration at the end-e ector, the accuracy of the arm angular position is improved signi cantly when these measurements are fused with motor angle observation. The problem is formulated in a Bayesian estimation framework and two solutions are proposed; one using the extended Kalman lter (e...

Sensor Fusion for Augmented Reality, Report no. LiTH-ISY-R-2875

The problem of estimating the position and orientation (pose) of a camera is approached by fusing measurements from inertial sensors (accelerometers and rate gyroscopes) and a camera. The sensor fusion approach described in this contribution is based on nonlinear ltering using the measurements from these complementary sensors. This way, accurate and robust pose estimates are available for the p...

Experimental Comparison of Observers for Tool Position Estimation of Industrial Robots, Report no. LiTH-ISY-R-2911

This paper investigates methods for tool position estimation of industrial robots. It is assumed that the motor angular position and the tool acceleration are measured. The considered observers are different versions of the extended Kalman filter as well as a deterministic observer. A method for tuning the observers is suggested and the robustness of the methods is investigated. The observers a...
