The Delta robot system is widely used in high speed (4 cycles/s at 25-200-25 mm) pick-and-place process in production line. Some industrial applications include photo-voltaic (PV), food process, and electronic assembly, and so on. The energy saving and system cost are two critical parameters for designing the next generation of pick-and-place system. To achieve these goals, a light-weight moving structure with sufficient strength to overcome the excited vibration will be one of the solutions. In this paper, an asymmetric arm design is proposed and fabricated to gain the benefit of strength-to-weight. The asymmetric arm is designed by reinforcing a specific direction and is validated the vibration suppression capability both by simulation and experiment. A position controller that is derived from the kinematic model of Delta robot is utilized to manipulate the robot under a forward-backward motion with a polynomial trajectory with 200 mm displacement. The residual vibration, then, was measured after the forward-backward motion to compare the settling performance between symmetric- and asymmetric-arms on the Delta robot system, respectively. The results conclude as following: (1) The asymmetric arms perform slightly worse (0.03 sec more in settling time) than symmetric arm but there is 15% weight reducing comparing to symmetric arm. (2) Both energy saving and system cost reducing would be achieved by utilizing actuators with lower power consumption and fabrication on carbon fiber arms with mass customization.


In our daily life we can see so many road accidents are increasing daily especially the bike accidents are increasing more and more because of so many things like high speed,drunk and drive ,riders not using helmet ,using mobile while driving and due to the late of ambulance in all these cases riders are not taking care of there lives and they are loosing there lives so we are going to introduce a "MULTI ACCESS HELMET" which will solve some of the above problems and we can reduce the accident rate by using this project. The essential purpose of this errand is to save a couple of presences of the people.This venture incorporate a few sensors like gas sensor ,ultrasonic sensor and vibration sensor .the gas sensor is utilized to recognize the liquor taken by the rider on the off chance that the liquor level is more prominent than the limit, at that point the ringer will be on and furthermore the red light will likewise on which show the threat sign and the rider won't ready to where the cap right now, on the off chance that he isn't wearing the head protector, at that point the bicycle additionally won't begin . Ultrasonic sensor will perceive the thing if the article is recognized in the more drawn out partition, by then also the chime will on and the red drove is on, it shows the rider to wear defensive top right currently bike won't begin.Vibration sensor is utilized to detect the vibration if the bicycle contacts the ground the recurrence scope of vibration increments on the off chance that it builds, at that point the area of the vehicle is followed utilizing the gsm and the message is sent to closest emergency clinics utilizing gps module..

<div class=""abs_img""> <img src=""[disp_template_path]/JRM/abst-image/00270005/11.jpg"" width=""300"" /> Defensive motion against attack</div> In this paper, we discuss how to generate defensive motions for a sword-fighting robot based on quick detection of the opposite player’s initial motions. Our sword-fighting robot system, which has a stereo high-speed vision system, recognizes both the position of a human player and that of the sword grasped by the robot’s hand. Further, it detects the moment when the human player initiates a move using ChangeFinder, which is a method of detecting change points. Next, using least squares method, it predicts the possible trajectories of the sword of the human player from the moment when the attack starts. Finally, it judges the type of the attack and generates an appropriate defensive motion. The effectiveness of the proposed algorithm is verified by experimental results. </span>
