The method includes spatial alignment of sensor images on short and long distance as well as a probabilistic fusion approach for combining multiple unimodal to multimodal image features. An experimental statistical comparison of uni- and multimodal image features is performed using RGB, IR and thermal cameras. Therefore, the sensors are mounted on an Ackermann steering platform in a typical industrial environment. The multimodal features are examined regarding repetitive characteristics, quantity and spatial distribution.","PeriodicalId":198633,"journal":{"name":"2017 18th International Conference on Advanced Robotics (ICAR)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128274310","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}

Increasing demands for manipulating soft objects have been reflected in the emerging 3C manufacturing, such as the soldering of flexible PCBs. Because of the property of deformation, soldering the flexible PCB cannot be performed with conventional robotic manipulation techniques. In this paper, an adaptive region controller is proposed to deal with the deformation of flexible PCBs, where the control objective is specified as a region attached to the flexible PCB. The proposed controller enables an additional assistive arm to reach the region and contact and fix the PCB, which thus eliminates the deformation. A coordination scheme is also developed to activate the soldering end effector after the deformation is stabilized. The stability of the closed-loop system is rigorously proved with Lyapunov methods, and experimental results are presented to illustrate the performance of the proposed controller.","PeriodicalId":198633,"journal":{"name":"2017 18th International Conference on Advanced Robotics (ICAR)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127342226","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}

However, these methods can be computationally expensive and might suffer from motion blur or images taken in structureless environments (e.g. forests). An alternative approach is the visual compass, a method which simulates a wide range of possible rotational offsets and searches for the best match. While this approach has been successfully implemented for rotations around a single axis, the increasing computation time for 3D rotations limits the usability for real-time applications. It has been suggested to use real spherical harmonics (RSH) to represent panoramic images, to calculate rotations in frequency domain using sparse matrix-vector multiplications. In this paper, we present strategies which are crucial to implement a real-time visual 3D compass using RSH. We provide a software implementation of the visual 3D compass and analyze the effect of increasing rotational misalignment between pairs of panoramic images. Furthermore, we show that the visual 3D compass can be used on low-cost hardware in real-time.","PeriodicalId":198633,"journal":{"name":"2017 18th International Conference on Advanced Robotics (ICAR)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128791752","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}

In this paper, we introduce a novel design for a soft bi-directional pneumatic actuator inspired by the principles of origami. The actuator integrates a variable stiffness application using a layer jamming mechanism (LJM). LJM utilizes the effects of negative pressure on thin layers of material, providing rigidity. Incorporated into an origami bellows structure, the negative pressure causes both contractile action and stiffness, while extensive action is caused by an internal pneumatic chamber, allowing for contractile and extensive force application. Furthermore, the variable stiffness integration improved tensile force application threefold, resistance to outside linear force tenfold, and doubled sheer force resistance. The proposed origami-inspired bi-directional soft pneumatic soft actuator has immense potential to be implemented in complex biomedical applications in the near future.","PeriodicalId":198633,"journal":{"name":"2017 18th International Conference on Advanced Robotics (ICAR)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125179839","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}

In the past, the task was very time-consuming and required a lot of manual works. In recent years, with some advances in the fields of automatic robotic system and computer vision, the task now can be completed with the help of an automatic taping system containing a 3D scanner, a manipulator and a rotating platform. This implementation has been proved to provide better quality and be at least twice as fast as comparing to the work done by a human operator. However, there are still some limitations of this setup. First, it is difficult for the user to monitor the taping process since the system uses the 3D scanner to reconstruct the surface model and there is no calibrated projector to overlay the manipulator's trajectory over the real surface. Second, the main user is supposed to use a computer with keyboard and mouse to identify the area for masking which requires some expert knowledge and might not be appropriate in an industrial context where people wear protective equipment such as gloves or helmet. This paper introduces the use of spatial augmented reality technology and wearable device in the semi-automatic taping robotic system and the related calibration algorithms to enhance the user experience.

We then use the motion database to efficiently estimate the simulated trajectory during iterations of our planner. When the planner requests the best control to reach a desired state from a query state, we retrieve nearby motions that are close to the query state and pick the motion that is closest to the desired state for the tree extension. To control accuracy of our planner with a high efficiency, we lazily validate retrieved motions.

This work attempts to interpret the biological method of controlling paired legs (here treated as dual-arms) in opposite and adjacent pairs to achieve a holistic controller of a large four-legged animal (here treated as a combined four-arm robot). A modular relative Jacobian controls a dual-arm as a single manipulator with a single end-effector, and is expressed in terms of the Jacobians of each of the stand-alone manipulators. In this work, the two opposite pairs of legs are treated as single end-effector dual-arms, and then these two dual-arms are combined together to form a single end-effector four-arm robot. The four-arm controller uses the same principle as a single end-effector controller of a dual-arm, and thus results into a single end-effector controller of a four-arm. A modular relative Jacobian of the four arms is derived.
