Seed: A Segmentation-Based Egocentric 3D Point Cloud Descriptor for Loop Closure Detection

IROS 2020poster

Place recognition is essential for SLAM system since it is critical for loop closure and can help to correct the accumulated drift and result in a globally consistent map. Unlike the visual slam which can use diverse feature detection methods to describe the scene, there are limited works reported t…

Motion Control of Piezo-Driven Stage via a Chattering-Free Sliding Mode Controller with Hysteresis Compensation

IROS 2018poster

This paper presents a novel sliding mode controller for trajectory tracking of the piezo-driven stage. The tracking performance of piezoelectric actuator is mainly affected by the hysteresis nonlinearity. Sliding mode control is a possible solution to achieve better tracking performance. However, co…
