However, making these systems fully autonomous and able to navigate safely in unpredictable real-world situations remains a big challenge. Fuzzy logic and related mathematical algorithms have emerged as practical tools to tackle uncertainty and complex decision-making in these systems. This paper reviews how fuzzy logic and mathematical approaches are applied in areas like navigation, control, avoiding obstacles, planning routes, and decision-making for AVs and UAVs. It delves into the key methods, designs, pros, and cons of using fuzzy logic in autonomous vehicles. The paper also compares fuzzy logic with other AI techniques. The review shows that fuzzy logic manages the uncertainties and imprecision involved in how autonomous vehicles perceive and navigate dynamic environments. Fuzzy controllers often perform better than traditional methods in vehicle control and UAV direction control. High-level decisions and route planning in AVs have also benefited from fuzzy inference systems. Still, challenges like computational efficiency, adaptability, and integrating fuzzy logic with other AI components remain. The paper concludes with suggestions for future research to make autonomous vehicles and drones smarter and safer using fuzzy logic.

Utilizing advanced computer vision techniques, OD systems automate processes, analyze complex visual data, and facilitate data-driven decisions, thus increasing productivity. Domain Adaptation for OD has recently gained prominence for its ability to recognize target objects without annotations. Innovative approaches that merge traditional cross-disciplinary domain modeling with cutting-edge deep learning have become essential in addressing complex AI challenges in real-time scenarios. Unlike traditional methods, this study proposes a novel, effective Cross-Pollination of Knowledge (CPK) strategy for domain adaptation inspired by botanical processes. The CPK approach involves merging target samples with source samples at the input stage. By incorporating a random and unique selection of a few target samples, the merging process enhances object detection results efficiently in domain adaptation, supporting detectors in aligning and generalizing features with the source domain. Additionally, this work presents the new Planeat digit recognition dataset, which includes 231 images. To ensure robust comparison, we employ a self-supervised Domain Adaptation (UDA) method that simultaneously trains target and source domains using unsupervised techniques. UDA method leverages target data to identify high-confidence regions, which are then cropped and augmented, adapting UDA for effective OD. The proposed CPK approach significantly outperforms existing UDA techniques, improving mean Average Precision (mAP) by 10.9% through rigorous testing on five diverse datasets across different conditions- cross-weather, cross-camera, and synthetic-to-real.

Robot gripper design is an active research area that seeks continuous improvements to cater to its wide spectrum of applications. Tetraonchus momenteron is an infamous parasite which has a robust gripping system (haptor) inserted into the fish-gills. We have redesigned this pull-based gripper for practical application by adjusting the link lengths using many-objective optimization. An existing pusher type of gripper mechanism is also selected to elucidate the similarities and dissimilarities between both the mechanisms. Both push and pull based grippers have been analyzed based on quasi static kinematics and are formulated as many objective optimization problems subjected to geometric-cum-force constraints. The goal of optimization is to find the best link lengths and joint angles for each configuration based on desired criteria. Four possible variants of piezoelectric actuator models are integrated into the optimization formulation to actuate the gripper models. These integrations have led to four different optimization problems for each case. Evolutionary many-objective optimization method is used to obtain non-dominated solutions. The optimized designs are compared based on objective function values to evaluate the performance of each gripper. The results of many-objective optimization are normalized and represented using parallel coordinate plots to aid the decision maker. Our comparative study reveals that while the new nature inspired pull based design has shown promising results in many cases, each gripper configuration has its own merits and requires decision maker’s intervention to choose a particular model based on specific requirement.</p>","PeriodicalId":44563,"journal":{"name":"International Journal of Intelligent Robotics and Applications","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142179062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is still a challenging issue today since four-legged creatures with incredibly complicated structures and precise motions are beyond the reach of current technology. This paper proposes a gait generation model for a spider robot that examines the guarantee between stability and speed. First, the robot spider’s movement rules are initiatively determined via four gait parameters—vertical step length, horizontal step length, leg lift, and knee bend. Meanwhile, the 3rd-order interpolation function determines the trajectory of the hips and feet at each leg. By applying analytical methods to solve the inverse kinematics issue, the orbits of the hips and feet at the four legs of the spider robot will be used to deduce twelve joint angle orbits at those locations. Then, a multi-objective function is proposed regarding both speed and stability based on the gait characteristics (gait parameters, CoP/ZMP trajectory) of the spider robot as to train the gait generation model by addressing the forward kinematics issue analytically. Finally, the multi-object MO-Jaya optimization technique is used to find four optimal gait parameters so that the spider robot performs a stable walking gait at the fastest speed. This proposal is implemented for the experiment B3-SBOT spider robot, simulation/experiment outcomes show that B3-SBOT moves at its fastest feasible speed while walking stably.</p>","PeriodicalId":44563,"journal":{"name":"International Journal of Intelligent Robotics and Applications","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142179099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome the cumulative errors, we then propose a discretized improved algorithm, which applies the virtual fixtures on a discretized reference curve. Furthermore, the orientation constraints are defined, and hence the end-effector orientation can also be constrained within a specific range to comply with ergonomics.
