For a team of robots to work collaboratively, it is crucial that each robot have the ability determine position their neighbors, relative themselves, in order execute tasks autonomously. This letter presents an algorithm for determining three-dimensional between two mobile robots, using nothing more than single ultra-wideband transceiver, accelerometer, rate gyro, and magnetometer. A sliding wi...

1.0 INTRODUCTION This paper presents a novel method of position estimation for Switched Reluctance (SR) Motor. The method is suitable from starting to full speed. It ensures smooth starting without initial hesitation. The method further incorporates a better position estimating algorithm incorporating corrections for excitation voltage and mutual inductance effects. The algorithm is better suit...

This paper describes developmental results of a new high-accuracy 2D visual marker for space application. It shows the results of experiments to evaluate the space environmental tolerance of the previous visual marker. It also shows the new redesigned marker based on the experimental results in conjunction with evaluation results of pose and position estimation by image processing. This new mar...
