The paper demonstrates a following robot with omni-directional wheels, which is able to take action to avoid obstacles. The robot design is based on both fuzzy and extension theory. Fuzzy theory was applied to tune the PMW signal of the motor revolution, and correct path deviation issues encountered when the robot is moving. Extension theory was used to build a robot obstacle-avoidance model. V...

This paper develops a distributed approach for fusing GMTI data with out-of-sequence (OOS) measurements. A multirate interacting multiple model (MRIMM) fusion algorithm is developed for e®ectively fusing multirate information. To incorporate an OOS measurement, two major steps are needed: retrospection from current time to OOS time and updating the current estimate with the OOS measurement, whi...

A more robust mean shift tracker using the joint of color and Completed Local Ternary Pattern (CLTP) histogram is proposed. CLTP is a generalization of Local Binary Pattern (LBP) which can be applied to obtain texture features that are more discriminant and less sensitive to noise. The joint of color and CLTP histogram based target representation can exploit the target structural information ef...

Due to the weak rigidity of an industrial robot, its end effector usually has poor absolute positioning accuracy, especially under varying payloads. Such situation is common in scenarios handling, machining and tool changing. Conventional off-line calibration or compensation methods can only eliminate systematic errors, while such are invalid dynamic errors brought by This paper proposes a deep...

A real-time adaptive segmentation method based on new distance features is proposed for the binary centroid tracker. These novel features are distances between the predicted center pixel of a target object by a tracking filter and each pixel in extraction of a moving target. The proposed method restricts clutters with target-like intensity from entering a tracking window and has low computation...

Based on the current situation of high precision and comparatively low APA (absolute positioning accuracy) in industrial robots, a calibration method to enhance robots is proposed. In view "hidden" characteristics RBCS (robot base coordinate system) FCS (flange measurement process, general proposed, source robot terminal position error classified into three aspects: RBCS, kinematics parameter m...

This paper finds upper bounds for the generalization error of three tracking algorithms when confronted with a worst case adversary. A system identification model is used where both the target and tracking network are single layer threshold networks, with the target weights changing slowly (the drift problem). Previous work considered random unbiased drifting adversaries. This paper focuses on ...

In this work, we present the results of our comparative evaluation of the Vocal Joystick system and the Eye Tracker system. Vocal Joystick is a non-verbal voice-based continuous mouse cursor control system that offers an alternative method of computer interaction for people with motor impairments. Our goal was to gain an understanding for how this system compares to an existing assistive techno...

This paper presents the development, validation, and deployment of the visual target tracking capability onto the Mars Exploration Rover (MER) mission. Visual target tracking enables targeted driving, in which the rover approaches a designated target in a closed visual feedback loop, increasing the target position accuracy by an order of magnitude and resulting in fewer ground-in-the-loop cycle...
