Online gait generation is done using Central pattern generator (CPG) control system for autonomous navigation of the snake robot. The illustration of the robot modelling has been performed both theoretically and experimentally.

Its success depends on the accuracy and reliability of its implementation and may depend on sensors which are used to acquire the environment data. This paper presents work on mapping which uses a low cost laser rangefinder, developed by Robopeak, RP Lidar. This work will be implemented on an autonomous mobile robot for indoor environment applications. Initially, a mobile robot incorporated with the sensor was developed after which a wireless monitoring and control station was established in order to perform data collection of the environments. A research laboratory with tables and equipment is used as a testbed. The collected data were analysed using three methods of pre-processing; i. raw filter, ii. a moving average of smooth filter, and iii. the combination of the raw filter and the moving average. The results show the environment map based on the raw data and the pre-processing performances. The combination of the raw filter and the moving average performs the best result. Besides, the scanning accuracy of the developed system is successful with more than 90% of correctness. As a conclusion, the laser rangefinder and the pre-processing used is capable to map the environment with clear image and hence can be used for a variety of applications.","PeriodicalId":175861,"journal":{"name":"2015 IEEE International Symposium on Robotics and Intelligent Sensors (IRIS)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123791033","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}

Two LDR sensors to measure and analyze the surroundings light intensity were allocated for one LED bulb. The LDR sensors interface with each other, and the necessary intensity required by the bulb will be calculated and the bulbs will provide the required lumen for the surrounding/workspace. This system is tested during the day time. The output would affected by surroundings light sources. Hence, the LED bulbs light intensity will be reduced causing a directly proportional effect to the power consumption.

The heat transfer for both heating and cooling is done using a single liquid. The system implemented with this concept is called Single Fluid Heat Transfer System (SFHTS). In this paper an actual SFHTS used by a pharmaceutical major company is considered. The essential objective is to eliminate overshoot and achieve set point in the shortest time possible for both thermal transfer unit and level control unit of SFHTS. Mathematical model of the real time SFHTS was developed and simulated using LabVIEW software. Tuned PI, PID and Sliding Mode Control were applied to the heating and cooling module (Thermal Transfer Module) and semi-automated level control module of the SFHTS. The results showed that all the controllers considered here aided in reaching the set point. However, the quantified results also denote that the swiftness and accuracy of the Sliding Mode Controller, the attributes required for faster settling time and overshoot elimination, was better than that of PI and PID Controllers. Hence Sliding Mode Controller was recommended for the thermal transfer module and semi-automated level control module of SFHTS.","PeriodicalId":175861,"journal":{"name":"2015 IEEE International Symposium on Robotics and Intelligent Sensors (IRIS)","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125845405","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}

Researchers concluded that the acquired maps are often inaccurate due to the limited field of view of the sensor. Therefore in this work, we complemented the Kinect with a laser scanner and proposed a method to merge the data from both sensors. Two SLAM algorithms (i.e Gmapping and Hector SLAM) were tested using the method, in different environments. The results show that the method is able to detect multi-sized objects and produce more accurate map as compared to when using single sensor (i.e Kinect only or laser scanner only). Finally, the performance of the Gmapping and Hector SLAM are compared particularly in terms of the computational complexity and the map accuracy.","PeriodicalId":175861,"journal":{"name":"2015 IEEE International Symposium on Robotics and Intelligent Sensors (IRIS)","volume":"306 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131817967","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}

Most system control techniques however are driven by the rate of error, thus as the quadrotor initially moves from ground position, the error rate is very high and in turn results in aggressive counter action from normal trajectory controllers. This in turn produces jerk. The more the jerk the greater the unwanted vibration, thus increasing settling time and reducing accuracy as hover state is approached. To curb this, we propose a controllably smooth and time optimal lift off procedure to be implemented on quadrotors.","PeriodicalId":175861,"journal":{"name":"2015 IEEE International Symposium on Robotics and Intelligent Sensors (IRIS)","volume":"271 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134012143","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}

Kinematic and dynamic analysis to build the system is proposed, while planning trajectory is provided by suggesting some cases to control a specific current crowd situation using Computed Torque Controller (CTC), which identifies the difference between the input desired trajectory with the newly collected data of the equation of motion and dynamic equation analysis of the actual system to achieve a good and accuracy results by reducing the error and minimize the disturbances. Simulation studies for a straightforward range of motion exercise were carried out, and experimental validation for the automated barrier with two DOF is performed to move the system forward and backward and avoid any obstacle on its path. The results obtained shows that the controller can track the desired position and trajectories for the barriers system motion, and adequately adapt the control parameters to the crowd conditions and the sensor and motor control performance.","PeriodicalId":175861,"journal":{"name":"2015 IEEE International Symposium on Robotics and Intelligent Sensors (IRIS)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122303923","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}
