ARSENAL (4-2-3-1)CECH, BELLERIN, KOSCIELNY, MERTESACKER, MONREAL, COQUELIN, CAZORLA, RAMSEY, OZIL, WALCOTT, GIROUDWEST HAM (4-2-3-1)SAKHO, JARVIS, PAYET, ZARATE, NOBLE, KOUYATE, CRESSWELL, REID, TOMKINS, BURKE, ADRIANArsenal approach the 2015-16 Barclays Premier League season with confidence, after a hugely impressive pre-season that earned them three trophies. The Gunners, who retained the FA Cup last May, won the Asia Cup in Singapore, the Emirates Cup at home and then the Community Shield, when manager Arsene Wenger beat Chelsea rival Jose Mourinho for the first time in 14 encounters with his rival.The Gunners are at home on the opening day for the fourth year in a row. But they do not boast an impressive recent opening-day record; last season’s 2-1 win at home to Crystal Palace was their first victory in the first game of the season since 2009, when they won 6-1 at Everton.West Ham, meanwhile, have already been busy under new boss Slaven Bilic, who replaced Sam Allardyce during the summer. On Thursday, the Hammers were in Europa League action, their sixth game of the competition.Bilic, who spent three years at West Ham as a player, is a popular choice amongst Hammers fans but he is without the injured Andy Carroll and Enner Valencia while Carl Jenkinson, signed on a second season’s loan from Arsenal, is ineligible to face his parent club.Arsenal will continue with Petr Cech, signed from Champions Chelsea at the age of 33. The keeper will wear the number 33 and has already impressed as the Gunners’ custodian.The Gunners hold the upper hand over their London rivals; they have won their last nine games in the league against West Ham and are unbeaten in their last 14 (winning 14 and drawing two). Indeed, West Ham last beat Arsenal in April 2007 at the Emirates Stadium.
1 Arsenal manager Arsene Wenger was unimpressed by his side’s ability to find the back of the net as they drew 0-0 with Southampton in the Barclays Premier League on Tuesday night.The Gunners were met by boos from frustrated fans as they saw their side unable to beat Saints goalkeeper Fraser Forster, despite 11 shots on target.Wenger said: “We produced quite a good performance, especially in the second half when we created 10 goal chances.“At the end of the day we came out with no goals.“I believe the performance we wanted to produce was there, but we cannot be happy with the way we finished our chances.“I think what’s most disappointing is some players missed some chances that usually they would take.“Our finishing is very bad at the moment – we have played three (league) games now without scoring a goal. In all those three games we had chances that we didn’t take. At that level it’s important.”Arsenal were the only team in the top six of the Premier League who failed to win on Tuesday night, and Wenger was frustrated at the result because he knew his side could do better. He said: “We started slowly but in the first half, a bit nervous because we lost our last game at home but in the second half it was one-way traffic.“We still couldn’t score. We didn’t make enough of our set pieces, we didn’t take them well, we didn’t finish well.“It’s just that our finishing was very poor.“It’s maximum frustrating, when your team puts the energy in and creates the chances.“When you have no chances you come out of the game thinking ‘Okay, there was not more in it.’ When you come out and you think there was much more in the game like that (tonight), when you have our ambition of course it’s frustrating.” Laurent Koscielny missed an easy header
FC Porto manager Sérgio Conceição insists the target remains the same, despite a qualification spot for the last-16 up for grabs tonightThe Primeira Liga leaders will host Schalke 04 in Portugal for a Champions League match needing just a point to book a place in the knockout stages.Currently, Porto leads Group D with 10 points from four games with Schalke trailing them by two points and third-place Galatasaray a further four points back.But, for Conceição, it makes no difference where they are in the standings as the goal remains the same as always – to win.“We look at every match with the same goal: getting the three points and put on a good performance,” Conceição told reporters on the club website.Top 5 Atletico Madrid players to watch in next week’s UCL Tomás Pavel Ibarra Meda – September 14, 2019 With the Champions League about to start, we need to start talking about the Top 5 Atletico Madrid players to watch in the competition.Atletico…“A victory will allow us to end the group stage in the lead and we know how important that is, but we are not under pressure at all.“We don’t think of the “what ifs?” in football. What matters is what we control, which is our performance.”Aside from striker Vincent Aboubakar remaining sidelined, Conceição has a fully-fit squad available for tonight.The Porto-Schalke match will begin at 21:00 (CET) at the Estádio do Dragão.

DOI: 10.1039/C6MH00550K The DeployBot can also walk with an ambulating gait, similar to the way a four-legged animal walks. However, this gait requires the robot to support its entire weight on only two legs, and the robot’s legs do not have enough lifting force to do this—at least, not on land. But by placing the robot under water, on the sandy surface of a water tank, the researchers took advantage of Archimedes’ principle which reduces the force required to lift the robot. Currently the robot moves very slowly, at a speed of a little over 2 meters per hour. The robot can also turn, but again at a slow rate, requiring 21 strides to turn 90 degrees. Although the robot is not fast, it could still serve as a useful tool for applications where speed is not important.Going forward, the researchers expect that the techniques used here could also be used to make modules of different shapes, leading to a wider variety of robot designs and functions. The researchers also noted that different methods of moving the robot besides an applied current could be investigated—for example, using pneumatic actuation, magnetic fields, or optical forces. They also suggest that the same approach used here could be used to fabricate microscale and nanoscale structures, which would open up a new range of applications. The researchers expect that the robot’s ability to be easily deployed, along with its low mass, low cost, load-bearing ability, compact size, and ability to be reconfigured into different forms may make it useful for applications such as space missions, seabed exploration, and household objects.The scientists, Wei Wang et al., at Seoul National University and Sungkyunkwan University, have published a paper on the new robot and other types of deployable structures that can be built using the same method in a recent issue of Materials Horizons.”The main advantage of this modular robot is robustness in various environments due to lack of mechanical systems such as motors and gears,” coauthor Sung-Hoon Ahn at Seoul National University told Phys.org. “Thus, problems facing motor-based robots, such as sealing and lubrication of mechanical systems in water or space environments, are not a problem for the smart actuator.”The robot, which the researchers call DeployBot, is assembled from eight modules: four for the body and one for each of the four legs. In their folded state, the modules lie flat, and after they are deployed they pop up into roughly a square shape. The modules are made of both rigid and flexible materials and contain embedded magnets that connect and lock multiple modules together. A shape memory alloy wire running through the square frame of each module is responsible for deploying and folding the modules, which takes several seconds but can be done repeatedly.

Credit: Wang et al. ©2017 Royal Society of Chemistry The researchers demonstrated that the DeployBot can walk with two different gaits. The first is an undulating gait, which is similar to the way an inchworm creeps across a surface. To do this, a four-step sequence of current is applied to generate an actuation wave through the robot’s body, from front to back. The imbalance in frictional contact with the ground between the front and back legs causes the robot to pull up its back legs while holding its front legs in place, resulting in forward motion. © 2017 Phys.org This document is subject to copyright.

(Phys.org)—Researchers have built the first robot made of soft, deployable materials that is capable of moving itself without the use of motors or any additional mechanical components. The robot “walks” when an electric current is applied to shape-memory alloy wires embedded in its frame: the current heats the wires, causing the robot’s flexible segments to contract and bend. Sequentially controlling the current to various segments in different ways results in different walking gaits.
