The Lane Keeping Assist (LKA) system has become a standard feature in recent car models. While marketed as providing auto-steering capabilities, the system's operational characteristics and safety performance remain underexplored, primarily due to lack of real-world testing comprehensive data. To fill this gap, we extensively tested mainstream LKA systems from leading U.S. automakers Tampa, Florida. Using an innovative method, collected dataset that includes full Controller Area Network...
Recognizing motions of tiny targets - only few dozen pixels in cluttered backgrounds remains a fundamental challenge when standard feature-based or deep learning methods fail under scarce visual cues. We propose STMDNet, model-based computational framework to Recognize at variable velocities low-sampling frequency scenarios. STMDNet designs novel dual-dynamics-and-correlation mechanism, harnessing ipsilateral excitation integrate target cues and leakage-enhancing-type contralateral...
Abstract The Enhanced Model Reference Adaptive Control (EMRAC) algorithm, augmenting the MRAC strategy with adaptive integral and switching control actions, is an effective solution to impose reference dynamics plants affected by parameter uncertainties, unmodeled disturbances. However, design of EMRAC solutions has so far been limited single‐input systems. To cover gap, this paper presents two extensions multi‐input mechanism both includes ‐modification assure boundedness gains also in...
The increased complexity of the tasks that on-orbit robots have to undertake has led an need for manipulation dexterity. Space can become more dexterous by adopting grasping and methodologies algorithms from terrestrial robots. In this paper, we present a novel methodology evaluating stability robotic grasp captures piece space debris, spent rocket stage. We calculate Intrinsic Stiffness Matrix 2-fingered on surface Apogee Kick Motor nozzle create metric is function local contact curvature,...
Conventional spacecraft Guidance, Navigation, and Control (GNC) architectures have been designed to receive execute commands from ground control with minimal automation autonomy onboard spacecraft. In contrast, Artificial Intelligence (AI)-based systems can allow real-time decision-making by considering system information that is difficult model incorporate in the conventional process involving or human operators. With growing interests on-orbit services manipulation, GNC faces numerous...
This paper adds on to the on-going efforts provide more autonomy space robots and introduces concept of programming by demonstration or imitation learning for trajectory planning manipulators free-floating spacecraft. A redundant 7-DoF robotic arm is mounted small spacecraft dedicated debris removal, on-orbit servicing assembly, autonomous rendezvous docking. The motion robot (or manipulator) induces reaction forces hence its attitude changes prompting Attitude Determination Control System...
As a critical target localization and imaging technology, multiple parameters estimation is an important research direction based on bistatic Multiple-Input Multiple-Output (MIMO) radar. This concentrates the Direction of Departure (DOD), Arrival (DOA), Doppler frequency joint incoherent targets. Furthermore, we design effective technique to decrease complexity when computing angles Temporal-spatial Nested Sampling signal model. First, it introduces multi-linear mapping mechanism efficiently...
Worldwide patent filings are at historically unprecedented levels. In 2011, the total number of applications for first time exceeded two million – double approximately 1.05 patents filed in 1995. Understanding what is behind this growth important, as it may indicate faster technological progress, new innovation models and strategic shifts how companies use system. Policymakers need to understand drives patenting worldwide, not least evaluate system can cope with increasing flow applications....
