Transporting payload with precise swing angles and transfer times poses a challenging task in building construction, which is why gantry crane systems are extensively utilized. Various control strategies, including open-loop and closed-loop systems, have been proposed to tackle this issue. However, most of these controllers rely on a model and parameters specific to the crane system, making the process of modeling and parameter identification complex and time-consuming. To address this challenge, this work presents a practical and simulation control method for automatic gantry cranes, which is evaluated simulation and experimentally. The lab-scale Gantry crane is developed in this work, which consists of mechanical and electrical parts. Proportional Integral and Derivative (PID) and Proportional Derivative (PD) controllers which applied optimization method are implemented in the electrical part of the system. The PID and PD controller applied in controlled the position and swing angle, respectively. The Gradient Decent optimization method is the best optimization method in determining the parameter of the controller, since it has the best simulation performance in the output of the system. The experimental result is developed and compared between simulation and lab-scale Gantry crane hardware implementation part. The performance of experimental results is shown appropriately approaching the performance of the simulation result, with the approximately settling time.

Recently, design for additive manufacturing has been proposed to maximize product performance through the rational and integrated design of the product, its materials, and their manufacturing processes. Searching design solutions in such a multidimensional design space is a challenging task. Notably, no existing design support method is both rapid and tailored to the design process. In this study, we propose a holistic approach that applies data-driven methods in design search and optimization at successive stages of a design process. More specifically, a two-step surrogate model-based design method is proposed for the embodiment and detailed design stages. The Bayesian network classifier is used as the reasoning framework to explore the design space in the embodiment design stage, while the Gaussian process regression model is used as the evaluation function for an optimization method to exploit the design space in detailed design. These models are constructed based on one dataset that is created by the Latin hypercube sampling method and then refined by the Markov Chain Monte Carlo sampling method. This cost-effective data-driven approach is demonstrated in the design of a customized ankle brace that has a tunable mechanical performance by using a highly stretchable design concept with tailored stiffnesses.

A real snake has simple figure like a string, and has highly adaptability corresponding to the environments/tasks. A snake-like robot mimics such highly adaptability of the real snake, is expected as an adaptable robot corresponding to the environments/tasks. Many literatures have reported with respect to locomotion controls of the snake-like robot, but haven't reported studies for applications. However, enhancement of the applications is required in real scenes of which the snake-like robot is expected to work. This paper reports to design the force controller to realize the cutting task by the snake-like robot, as a leading example of the force control in the real scenes. Since the force control in the feed direction and the servo control in its normal direction are required in order to realize the cutting task, the Dynamic Hybrid Position/Force Control System is designed. The Virtual Internal Model based on the impedance model is utilized as the force control method. The Model Following Servo Control System utilizing the Virtual Internal Model based on the impedance model is designed, and the Dynamic Hybrid Position/Force Control System is realized. Effectiveness of the designed control system is verified through a numerical simulation.

Strawberry is a very delicate fruit that requires special treatment during harvesting. A hierarchical control scheme is proposed based on a fuzzy controller for the force regulation of the gripper and proper grasping criteria, that can detect misplaced strawberries on the gripper or uneven distribution of forces. The design of the gripper and the controller are based on conducted experiments to measure the maximum gripping force and the required detachment force under a variety of detachment techniques. It is demonstrated that the hand motion for detaching the fruit from the stem has a significant role in the process because it can reduce the required force. By analysing those results a robotic gripper with pressure profile sensors is developed that demonstrates an efficiency comparable to the human hand for strawberry grasping. The designed gripper and fuzzy controller performance is tested with a considerable number of fresh fruits to demonstrate the effectiveness to the uncertainties of strawberry grasping. © 2014 Cambridge University Press.

A novel approach to gait synchronization and transition for reconfigurable walking platforms

Digital Communications and Networks 2015年第2期1卷 141-151页

Legged robots based on one degree-of-freedom reconfigurable planar leg mechanisms, that are capable of generating multiple useful gaits, are highly desired due to the possibility of handling environments and tasks of high complexity while maintaining simple control schemes. An essential consideration in these reconfigurable legged robots is to attain stability in motion, at rest as well as while transforming from one configuration to another with the minimum number of legs as long as the full range of their walking patterns, resulting from the different gait cycles of their legs, is achieved. To this end, in this paper, we present a method for the generation of input joint trajectories to properly synchronize the movement of quadruped robots with reconfigurable legs. The approach is exemplified in a four-legged robot with reconfigurable Jansen legs capable of generating up to six useful different gait cycles. The proposed technique is validated through simulated results that show the platform's stability across its six feasible walking patterns and during gait transition phases, thus considerably extending the capabilities of the non-reconfigurable design.

Legged robots are able to move across irregular terrains and some can be energy efficient, but are often constrained by a limited range of gaits which can limit their locomotion capabilities considerably. This paper reports a reconfigurable design approach to robotic legged locomotion that produces a wide variety of gait cycles, opening new possibilities for innovative applications. In this paper, we present a distance-based formulation and its application to solve the position analysis problem of a standard Theo Jansen mechanism. By changing the configuration of a linkage, our objective in this study is to identify novel gait patterns of interest for a walking platform. The exemplary gait variations presented in this work demonstrate the feasibility of our approach, and considerably extend the capabilities of the original design to not only produce novel cum useful gait patterns but also to realize behaviors beyond locomotion.

This paper presents the main highlights of a Human-Robot Interaction (HRI) study conducted during a manipulation experiment performed in Cave Automatic Virtual Environment (CAVE). Our aim is to assess whether using immersive Virtual Reality (VR) for testing material handling scenarios that assume collaboration between robots and humans is a practical alternative to similar real live applications. We focus on measuring variables identified as conclusive for the purpose of this study (such as the percentage of tasks successfully completed, the average time to complete task, the relative distance and motion estimate, presence and relative contact errors) during different manipulation scenarios. We present the experimental setup, the HRI questionnaire and the results analysis. We conclude by listing further research issues. © 2011 Springer-Verlag.

Virtual Reality has known exponential development in the recent years and presents important research vectors for the years to come. One major issue, unresolved yet, remains the totally immersion feeling in Virtual Environment (VE) and one of it's most important aspects still to be researched is locomotion in VE. In this direction the authors propose a bidirectional active treadmill based device adapted from an ordinary unidirectional treadmill. The device is used for researching a way to walk smoothly and in an undisturbed fashion on a very limited surface area. For controlling the treadmill's speed and direction the authors propose two simple algorithms. The implementation of the algorithms, experimental setup, tests and results are presented as well. The author's discussion including a critical perspective about the results is also reported. The final part concludes this paper with the authors' perspective and future vectors to be implemented and researched still. © 2011 IFIP International Federation for Information Processing.
