Although the soft robot shows promise as an examination method due to its safe human-machine interaction and high maneuverability, achieving controlled and non-damaging movements within the flexible and delicate structure of the intestines remains a significant challenge. In this study, we propose and design a leech-inspired soft robot capable of operating in an intestine-like environment while ensuring lossless and controllable functionality. The soft robot consists of two dual-chambered adsorption actuators serving as “feet” and a retractable actuator as the body, enabling the robot to crawl by programmatically controlling the alternating movements of the adsorption actuators and the cooperation of the retractable actuator. Through numerical simulations, and movement tests in various scenarios such as planes, slopes, and intestine-like pipelines, we verified the adsorption characteristics and regulation mechanism of the adsorption actuator, as well as the movement performance of the robot. The results demonstrate that the adsorption actuator achieves a maximum adsorption force of 3.17 N, and the soft robot attains a maximum moving speed of 9.29 mm/s.

UAVs can be utilized for a wide range of applications, including mapping, surveillance, and inspection. For many of these applications, a high level of autonomy is required. Autonomy refers to the ability to complete missions or tasks without human intervention. Autonomous navigation is an essential element of autonomy, especially in GPS-denied environments where GNSS-based navigation is not reliable. Due to size and weight limitations, many UAVs employ vision-based localization and navigation techniques for GPS-denied environments. Reinforcement Learning (RL) is also increasingly being implemented for robotic applications, including obstacle avoidance, battery management, and navigation. Existing reviews typically focus on either vision-based autonomous navigation of drones or RL navigation for drones in general, but none specifically concentrate on the use of vision-based methods and RL for drone navigation. Moreover, previous reviews have highlighted the use of reinforcement learning based on tasks such as takeoff, landing, and navigation, whereas this review categorizes the use of RL based on the navigation problem and image input types for the RL models as these define the needed hardware and processing capabilities of the system. We define the current challenges and limitations for vision based RL navigation to provide direction for future works.

In this paper, we develop two sets of nonlinear equations of motion for a DAV to create a multi-purpose dynamic model for designing control and transition mode scenarios. The first set considers the multicopter torque as the control input, while the second set considers the elevator torque as the control input. By analyzing three transition scenarios between multicopter hover and fixed-wing cruise flights, we observe that the best performance occurs for the third scenario in which the control system switches from multicopter control torque to elevator control torque when the multicopter thrust equals the wings’ lift. In this case, the vehicle will be protected from critical flight conditions like wing stalls while the transition will go smoothly with minimum height drop. The transition mode strategies are implemented using a model predictive controller in flight simulation.

This challenge stems from the need to account for inter-joint relationships, which define constraints between different robot joints due to the kinematic structure, and intra-joint relationships, which are constraints within a single joint like limits. Accounting for these coupled, nonlinear inter-joint and intra-joint relationships is crucial for trajectory planning. However, various constraints in the physical capability of robots, environmental changes, and long-time reliance on sequential dependencies between these inter-joint and intra-joint relationships make the work of modifying robot trajectories exceptionally hard. Many robot environments function under structured static work-cell completing extended series of subtasks. The conventional descriptors for robot trajectory rely on symbolic rules with human intelligence, which involves skilled individuals and possesses significant limitations, such as being time-consuming and exhibiting low flexibility even for minor changes, due to the static nature of task descriptions alone. The suggested technique employs a probabilistic network and data-efficient modelling termed generative adversarial networks, which learns the underlying constraints, probability distributions and arbitrations, along with generating trajectory instances at each time of sampling. Integrating prior knowledge into the symbolic trajectory learner as a dataset facilitates the learning process. The model assessment was carried out by utilising a custom-built dataset in a simulation based environment. This research also proposed two GAN inversion methods to compute the generated trajectory and its closest instance in the dataset. Furthermore, GAN Inversion method I and II calculated the robot path accuracy in extrinsic generative models yielded path position accuracy of 9.2 cm and 4.9 cm respectively.

Thought of initially as humanoid automata a century ago, this viewpoint is still influential in modern robot design. Many robotic grippers are inspired by the deftness of the human hand. The perceptual, processing, and control issues that conventional grippers have are also experienced by soft-fingered grippers. Precise finger placement, dictated by the shape and attitude of the object, is necessary to accomplish force closure when using soft fingertips to grasp. Soft robotic end-effectors have several advantages, such as a good interface with humans, the capacity to adapt to different environments, a number of degrees of freedom, and the ability to non-destructively grasp items of various shapes. Adding to earlier research that looked at the soft robot in a theoretical way, this study creates an optimized model based on the deformation in terms of bending of the channel cavity under applied pneumatic pressure. A correlation between pneumatic pressure and the pneumatic soft actuator's bending angle has been demonstrated. This research looks at how different design factors affect the bending of a multi-chambered soft actuator that is pneumatically networked. The finite element approach involves fine-tuned (optimised) actuator construction. Using FEM to evaluate aspects affecting actuator mechanical output, the ideal design parameters were discovered using DoE, resulting in a bending angle of ~ 104 degrees at 30 kPa. This study used ANOVA at a 5% significant level to identify which variables most affected the pneumatic actuator's deformation (bending angle). The significant R-square value of 96.42% supports the study's conclusions that the parameters utilised explain an immense percentage of bending angle deviations. Experimental verification of the optimized finite element model findings was conducted. The verification of the actuators' bending angles and output forces reveals that the discrepancy between the two sets of data stayed below 9%. Also, the average gripping success rate attained in the grasping evaluation, which involved four distinct types of items, was almost 97%.</p>","PeriodicalId":44563,"journal":{"name":"International Journal of Intelligent Robotics and Applications","volume":"31 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141502907","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}
