A sliding control approach is combined with a control allocation process to solve the overactuated control problem. The control allocation problem is solved using nonlinear programming software which allows the optimization problem to be solved with input saturation constraints. Furthermore, a low level trajectory controller based on dynamic feedback linearization is developed in order to improve the trajectory tracking performance of the individual swarm members. Application to a group of wheeled mobile robots is used to demonstrate the approach. Together, these results allow energetic swarm controllers to be implemented on wheeled mobile robot (WMR) systems with uncertainty and input saturation constraints.","PeriodicalId":321332,"journal":{"name":"2008 IEEE International Conference on Robotics and Biomimetics","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127894908","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}

It reports on the outcome of a feasibility study, where a biomimetic robotic actuator was used to demonstrate effective soft tissue traversal (i.e. motion along the surface of a soft tissue) through the reciprocating motion of custombuilt anisotropic surface textures, without the need to apply an external force to push the tissue along the surface and while causing minimum tissue damage. The protocol applied to characterize the interaction between the samples and the different tissues was considered, including parameters such as texture size and geometry, normal load, frictional forces and reciprocating speed and acceleration. A number of microtextured samples, with features including every combination of two teeth geometries (triangular and fin-like) and three tooth sizes (500µm, 100µm and 50µm tooth height), were manufactured and mounted onto a custom-built reciprocating mechanism. First, a variety of soft tissue specimens was tested to qualify the sample/tissue interaction behavior. Subsequently, a comparative study on agarose gel and gelatin was performed to investigate the motion characteristics and resulting tissue damage on brainlike material and to explore what conditions are needed to achieve forward motion.","PeriodicalId":321332,"journal":{"name":"2008 IEEE International Conference on Robotics and Biomimetics","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115165181","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}

Several researchers have succeeded in catching the free-frying object by the robotic hand. However, these researches focus on only the catching and do not discuss the grasp configuration after the catching. It is important to consider not only the stable catching but also the following manipulation after the catching as seen in a juggling and a baton twirling. We propose the strategy that enables the robotic hand to catch the object with a high manipulability grasp configuration and verify the proposed strategy experimentally by using the newly developed three-fingered hand.","PeriodicalId":321332,"journal":{"name":"2008 IEEE International Conference on Robotics and Biomimetics","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116943320","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}

Another kind of the startle response is also evident in the cockroaches Periplaneta and the crickets Gryllus bimaculatus where they use their cercal filiform hairs (wind sensitive hairs) to trigger so called “wind-evoked escape behavior”. Similarly, in this paper a setup is described where an auditory-wind detector sensor and a neural preprocessing system together with a modular neural controller are used to simulate such animal behaviors in an abstract form on a six-legged walking machine. The neural preprocessing network acts as a low-pass filter and sensory shaping unit. In addition, the modular neural controller then generates the desired responses such that the machine performs a fast movement away from abrupt, intense, and unexpected auditory and/or wind stimulus in a physical environment.","PeriodicalId":321332,"journal":{"name":"2008 IEEE International Conference on Robotics and Biomimetics","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122022095","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}

We present a novel synergy-based approach for operator interfaces, by introducing a series of octopus-arm inspired grasp-synergies. These grasp-synergies automatically coordinate the degrees of freedom of the continuum manipulator, allowing an operator to perform kinematically complex grasping motions through simple and intuitive joystick inputs. This effectively reduces the complexity of operation and allows the operator to devote more of his attention to higher-level concerns (e.g. goal, environment). We demonstrate the grasp-synergies interface design in both simulation and hardware using the nine degree of freedom Octarm continuum manipulator.","PeriodicalId":321332,"journal":{"name":"2008 IEEE International Conference on Robotics and Biomimetics","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114831650","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}

The shape and motion propagation of the snake robot directly affect the forward crawling speed of the robot inside a pipe. Motion shape code is proposed as the simplified method for describing shape of a modular snake robot. The motion propagation can be created by shifting the code to the adjacent joint. Five different motion shapes were tested on the 12-joints modular snake robot that moved inside a pipe with varied inclined angles. The experimental results showed that the motion shape that has the maximum number of waves along the robot length and the largest basis angle resulted in the fastest forward crawling speed.","PeriodicalId":321332,"journal":{"name":"2008 IEEE International Conference on Robotics and Biomimetics","volume":"387 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124797386","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}

Attention is directed toward the most salient location in the saliency map. The mechanism of ‘inhibition of return’ (IOR) suppresses the saliency of recently attended location and thereby enabling the shifts of attention toward different locations in the saliency map in order of decreasing saliency. This process performs well as longs as the attention is directed covertly. For overt attention with head movements, which is practically the case in robotic applications, the visual saliency as well as the frame of reference in which the IOR is expressed change after every head movement. These pose a set of computational challenges in implementing attention behavior and IOR. This paper argues that the re-mapping of visual saliency and dynamic shift of IOR emerge naturally in a particle filter based framework of visual attention. Experiments on a real camera head validate the arguments.","PeriodicalId":321332,"journal":{"name":"2008 IEEE International Conference on Robotics and Biomimetics","volume":"185 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123263156","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 propose a method of sensorimotor learning and evaluate it performance in active learning. The proposed model is characterized by a function we call the “confidence”, and is a measure of the reliability of state prediction and control. The confidence for the state can be a good measure to bias the next exploration strategy of data sampling, and to direct its attention to areas in the state domain less reliably predicted and controlled. We consider the confidence function to be a first step toward an active behavior design for autonomous environment adaptation. The approach was experimentally validated using the humanoid robot James.","PeriodicalId":321332,"journal":{"name":"2008 IEEE International Conference on Robotics and Biomimetics","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123299301","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}
