In this paper, a novel two parallel robots cooperation system which can handle objects with large volume and heavy weight is developed by optimizing the traditional Cartesian parallel mechanism (CPM). Forward and inverse kinematics of the improved CPM-based parallel robot and the kinematic constraint of the two robots are derived. Moreover, the trajectories of two robots are planned based on the established kinematic models. An iterative learning control strategy is developed to control the driving torques in the robot joint space. Finally, the model of the system is established via SimMechanics and simulated in Matlab environment.

The simplest is the use of a proportional-integral-derivative (PID) feedback control which usually regulates the position or the interaction force along a known reference. Nonetheless PID method cannot achieve an ideal tracking performance due to dynamical uncertainties and unknown time-varying periodic disturbances from the environment. In order to minimize steady-state error with respect to uncertainties in exoskeleton passive control, Iterative Learning Control(ILC) and Neural PID control are proposed to improve the control effective of conventional linear PID. In this paper, two different control algorithms are introduced.

However, the excellent kinematics performance and the high joint-driving torque are required for establishing such exoskeleton robots, which have become the major technical obstacle for practical applications of exoskeletons. A novel powered hip exoskeleton robot with hydraulic servo rotary drive is presented, both greater power to weight ratio and admirable rotating property similar to the servo motor can be achieved. In order to set up the range of motions and torque requirements of hip joints, the human's gait cycle and the lower limb physiology characteristics are analyzed. Based on the data analyses of human lower limbs, a rotary hydraulic driving device for hip flexion and extension (Al/Ex) is proposed, which is combined with the motion characteristic of hydraulic and the rotary motor. The designed new type of powerassisted hip exoskeleton can satisfy a variety of action like normal walking, like going up and down the stairs and bending down, etc. This work not only introduces the design details of the power-assisted hip exoskeleton with hydraulic servo rotary drive, but also provides a new actuating device for future research of the multi-joint lower limbs power-assisted robots design.

The soft robot is consist of two soft actuators and three unidirectional crawling foots, all of which are fabricated by casting two-component RTV (room temperature vulcanized) silicone rubber in a three-dimensional (3-D) printed customized mold. The gait of the soft robot based on the simplified model of the earthworm's motion is designed. The soft actuator is composed of a cylindrical main body with a cylindrical chambers embedded in and a spring wrapping around the body. Since the spring limits the expansion in radial direction, the deformation of the soft actuator happens only in the axial direction by compressed air. The soft robot crawls faster and efficiently with the help of unidirectional crawling foots. The experiment shows that the soft robot can move forward continuously on condition of actuators expanding and contracting in a regular pattern.","PeriodicalId":125468,"journal":{"name":"2016 23rd International Conference on Mechatronics and Machine Vision in Practice (M2VIP)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128665196","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, even though automated vein detection is fundamental for the collection of objective quantitative results that can be implemented in resource models, related published literature is limited. While image analysis can be potentially used to segment veins from a drill core image, it may not always work due to the complexity of the drill core image. When the color and texture of a vein is not obviously contrasted to its background in a drill core image, the vein may not be detected at all. This paper presents a data fusion based approach for mapping quartz and carbonate veins in drill cores. The proposed approach uses different image analysis techniques together with the abundance data of minerals produced from the unmixing of the thermal infrared (TIR) and short-wave infrared (SWIR) spectra. The experimental results show that the proposed data fusion method successfully logged the quartz and carbonate veins and has laid the groundwork for further development to ‘paint’ the results onto drill core imagery.","PeriodicalId":125468,"journal":{"name":"2016 23rd International Conference on Mechatronics and Machine Vision in Practice (M2VIP)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132874537","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}
