The hand is designed to be an end effector for industrial and service robots. The main objective is to develop a low-cost, low-weight and easily manufacturable robotic hand with a sensor module allowing acquisition of data for autonomous intelligent object manipulation. 3D printing technologies were extensively used in the implementation of the hand. Specifically, the structure of the hand is printed using a 3D printer as a complete assembly voiding the need of using fasteners and bearings for the assembly of the hand and decreasing the total weight. The hand also incorporates a sensor module containing a LIDAR, digital camera and non-contact infrared temperature sensor for intelligent automation. As an alternative to teach pendants for the industrial manipulators, a teaching glove was developed, which acts as the primary human machine interface between the user and the NU Hand. The paper presents an extensive performance characterization of the robotic hand including finger forces, weight, audible noise level during operation and sensor data acquisition.","PeriodicalId":335884,"journal":{"name":"2013 IEEE International Conference on Mechatronics and Automation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128903552","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, a recently developed wearable lower extremity rehabilitation device is introduced, and an adaptive control strategy based on Function Approximation Techniques (FAT) is designed to aid stroke patients who are in the early phase of rehabilitation or severely affected. The device adopts an anthropomorphic structure actuated on hip and knee joint level in sagittal plane. Frameless DC motor with high gear-ratio harmonic drive is used as actuator. Fourier series fitting method is used to obtain the desired hip and knee reference trajectory. This control algorithm is then implemented in the device with friction compensation to track the desired gait trajectory. Implementation results for a healthy subject show that good tracking performance can be achieved, and actuator toques are within a reasonable range. This FAT based adaptive control algorithm could potentially be used for stroke patients as well.","PeriodicalId":335884,"journal":{"name":"2013 IEEE International Conference on Mechatronics and Automation","volume":"82 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131660519","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}

Some operational tasks can be performed significantly better by robots than humans due to associated hazards and distance. However, the significant disadvantage of this surgical technique is its complexity; therefore, extensive training before surgery is necessary. At present, the operator can only determine the required action by visually examining in remote side which limits the task. In this paper, we present virtual reality technology based simulators for doctor training with force feedback in minimally invasive surgery. The simulators allow generating realistic physical-based model of the catheter and blood vessels, and enabling surgeons to touch, feel and manipulate the virtual catheter inside vascular model according to the same surgical operation mode used in actual MIS.

To cover a wider range of navigation tasks, this paper presents a novel waypoint navigation method in polar coordinate. Navigation limit cycle avoidance is handled by creating and memorizing a specific traversable but less preferred areas during waypoint navigation in which the robot changes its orientation to follow from goal-directed to opportunistic goal-repulsive behavior. This allows the robot to be able to predict, thus avoiding upcoming limit cycle situations. The saving of time and memory resources of path computation using the novel polar-coordinate based waypoint navigation has been verified by simulations, and an implementation of the navigation method on a real mobile robot works well in an indoor experiment with demonstrated planning and route selection capabilities for waypoint navigation.","PeriodicalId":335884,"journal":{"name":"2013 IEEE International Conference on Mechatronics and Automation","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114206806","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}

To achieve the greater performance of electric path and heat dissipation ability, the metal core PCB (MCPCB) is used to replace the common FR4 PCB. The MCPCB is composed of copper film, dielectric and metal base. Metal base is made of copper or aluminum and has high thermal conductivity to conduct heat from LED to heat sink. However, the low thermal conductivity of dielectric layer in the middle of MCPCB will cause the temperature raise. In this study, we use 30% diamond powder as the filler of dielectric layer and combined the PCB and flat plate heat pipe (PCB-FPHP) without metal base to enhance the effective thermal conductivity. In order to verify the performance of diamond powder PCB-FPHP, we experimental measured the PCB-FPHP and common MCPCB conducted with 3 different materials include Cu, Al and FPHP by IR camera. The experimental results shows that the thermal resistance of PCB-FPHP is 36%, 78% and 86% lower than MCPCB-FPHP, MCPCB-Cu, and MCPCB-Al respectively. It is obviously that the thermal resistance of metal base and the thermal grease cannot be neglected especially in high power application. The structure of PCB-substrate we propose in this paper can reduce the junction temperature about 0.36°C/W compare with MCPCB-substrate. It is a meaningful number for high power LED application.","PeriodicalId":335884,"journal":{"name":"2013 IEEE International Conference on Mechatronics and Automation","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121082102","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}
