Robotic hex-nut sorting system with deep learning

<span>This article exposes the design and implementation of an automation system based on a robotic arm for hex-nut classification, using pattern recognition and image processing. The robotic arm work based on three servo motors and an electromagnetic end effector. The pattern recognition implemented allows classifying three different types of hex-nut through deep learning algorithms based on convolutional neural network architectures. The proposed methodology exposes four phases: the first is the design, implementation, and control of a robotic arm. The second is the capture, classification, and image treatment; the third allows gripping the nut through the robot’s inverse kinematic. The final phase is the re-localization of the hex-nut in the respective container. The automation system successfully classifies all the types of hex-nuts, where the convolutional network used is an efficient and recent pattern recognition method, with an accuracy of 100% in 150 iterations. This development allows for obtaining a novel algorithm for robotic applications in hex-nut sorting.</span>

OLYMPIC TEAM ROWER STROKE TECHNICAL ANALYSIS

It is much spoken about and researched how to increase the speed of moving in rowing. Many scientists have researched the technical aspects in rowing. Most part of researches is based on oxygen maximal consumption and other physiological changes during a load. Although there are various researches, stating the technical nuances of leg and arm work, comparatively little attention is paid to the role of the arm work. The cycle length in different distances and having different water flow – before the wind, against the wind and with the side wind is stated. The aim was to research one stroke technical nuances in rowing looking for stroke rate from 24 till 34. A pilot study was carried out. One Lithuanian Olympic team rower was participated this pilot study and he was tested in different stroke rate. The following methods were used in study: test exercise, video analysis with KinezioVideoAnalyzer 3.0. and mathematical statistics. The results: having stated the result average of stroke rate was 28,6 and speed of stroke was 0,82 sec. Conclusions: the obtained data from rower show small differences changing stroke rate.

The Structure of Performance of a Sport Rock Climber

This study is a contribution to the discussion about the structure of performance of sport rock climbers. Because of the complex and multifaceted nature of this sport, multivariate statistics were applied in the study. The subjects included thirty experienced sport climbers. Forty three variables were scrutinised, namely somatic characteristics, specific physical fitness, coordination abilities, aerobic and anaerobic power, technical and tactical skills, mental characteristics, as well as 2 variables describing the climber’s performance in the OS (Max OS) and RP style (Max RP). The results show that for training effectiveness of advanced climbers to be thoroughly analysed and examined, tests assessing their physical, technical and mental characteristics are necessary. The three sets of variables used in this study explained the structure of performance similarly, but not identically (in 38, 33 and 25%, respectively). They were also complementary to around 30% of the variance. The overall performance capacity of a sport rock climber (Max OS and Max RP) was also evaluated in the study. The canonical weights of the dominant first canonical root were 0.554 and 0.512 for Max OS and Max RP, respectively. Despite the differences between the two styles of climbing, seven variables - the maximal relative strength of the fingers (canonical weight = 0.490), mental endurance (one of scales : The Formal Characteristics of Behaviour-Temperament Inventory (FCB-TI; Strelau and Zawadzki, 1995)) (-0.410), climbing technique (0.370), isometric endurance of the fingers (0.340), the number of errors in the complex reaction time test (- 0.319), the ape index (-0.319) and oxygen uptake during arm work at the anaerobic threshold (0.254) were found to explain 77% of performance capacity common to the two styles.

Design and Control on Automobile Crane Torque Limiter

AMLU torque limiter is an automobile crane moment limiter. The torque limiter is detection vehicle crane lifting weight. Moment limiter can detect and display the gravity and torque dynamic change value. Vehicle mounted crane in the course of their work to detect arm angle and length, amplitude of cylinder pressure and other parameters. Vehicle mounted crane arm angle and length can be changed. Arm length detection is accomplished by length conversion mechanism. The same arm work angle detection need angle conversion mechanism. Arm length variation measurement using a retractable cable. Retractable cable tension is detected by the arm length of variable key content. Disc springs were used on the telescopic pull wheel force. Detection angle variation value using the weight arm angle converting mechanism. The angle conversion mechanism inside the box body of the injection of silicone oil can increase the oscillating damper. Reduce the detection angle fluctuation. Detection of signal processing and computer hardware design were also introduced.
