The Premier League is one of the greatest football competitions in the world, featuring 20 teams from England and Wales.

This weekend's Premier League offers plenty of thrilling matches. The Big Four are determined to maintain their dominance, but there is action all around the table too.

1. Manchester City vs. Liverpool

Manchester City and Liverpool's meeting is always eagerly anticipated in the Premier League, as it has always been close to both clubs' hearts. Expect plenty of tension both on and off the pitch during this fixture that has always held such special significance for both clubs.

Liverpool have an excellent opportunity to regain the top of the table with City having dropped seven points in their last 10 matches and now seven behind Liverpool. A win here would reduce that gap to just two points.

Pep Guardiola's team have gone undefeated since mid-November, yet they still lack clinical edge. If they want to secure victory before the World Cup break, Pep must find ways of improving in the final third of games.

2. Chelsea vs. Tottenham

Chelsea have an important London derby to contend with this weekend as they take on Tottenham in a match that could determine their title hopes. It's the first big-six match of the season and will provide insight into just how strong these teams are compared to each other.

Tottenham's 2-0 home victory against Chelsea in their most recent Premier League encounter has put even more pressure on Blues boss Graham Potter. With 14 matches remaining in the season, Tottenham are 14 points clear of fourth-placed Chelsea with 14 matches left to play.

Last week, Skipp and Hojbjerg excelled in the absence of Rodrigo Bentancur, scoring two goals to help Tottenham secure its first league victory against bitter London rivals since moving into their new stadium. It's an impressive display from them both and one that should encourage Spurs going forward.

3. Manchester United vs. Southampton

On Monday night, Manchester United enjoyed a rewarding victory against Liverpool and now have the chance to build on that momentum against Southampton this weekend. To sustain their impressive fight in beating Liverpool, Erik ten Hag will be hoping it carries over into this match.

The Saints will be looking to make it back-to-back Premier League victories after picking up four points from their opening two matches this season. This test of confidence for them is a crucial one as it provides some much needed momentum heading into the second half of the season.

Danny Ings and Gavin Bazunu are two key players who could be decisive in this match, but Ings has a history of getting his hands on the ball and scoring goals in big matches; thus, it's important to keep him quiet.

4. Liverpool vs. Everton

The Merseyside derby is always an exciting match, and this one promises to be no different as Liverpool seek their first win of 2023 against Everton in what promises to be a crucial contest for the Reds.

Klopp's side are still fighting to stay in the top four, while Everton will be hoping for a boost ahead of their crucial match against Leeds on Saturday. The Toffees sit 18th in the table and have recently welcomed new boss Sean Dyche, whose side beat league leaders Arsenal last time out.

The Reds had the better of the game and were rewarded with a 2-0 victory. Mohamed Salah opened the scoring after an impressive counterattack, while Cody Gakpo added another goal to complete a convincing win for Klopp's men. It was certainly a satisfying triumph for Liverpool.

5. Manchester City vs. Bournemouth

Manchester City are in the thick of the Premier League title race and need to win this weekend. The reigning champions travel to Bournemouth on Saturday as they attempt to bounce back after an unexpected draw with Nottingham Forest last weekend.

City must win this match to increase their title chances and keep the pressure on Arsenal. Furthermore, they must ensure their key players remain healthy.

City have won 12 straight games against Bournemouth and are the favorite to win this game. Their strong defense can be the difference in this contest. City also have some quality players that could score this weekend, including Erling Haaland (26 goals), and Kevin De Bruyne who could play a significant role.

6. Tottenham vs. Chelsea

Chelsea and Tottenham Hotspur are both eager for their first win of the season when they meet at Stamford Bridge on Sunday. Spurs have been on a roll since their defeat at Southampton, and could take the lead in Premier League table with victory over Chelsea.

The Premier League table is determined by points scored by teams during a season, with the top two qualifying for the Champions League and the bottom three being relegated to the Championship.

Chelsea have suffered a run of bad luck recently, losing six straight matches to fall 14 points behind Spurs in fourth. Graham Potter faces mounting pressure and this game against Southampton will be an important test to see if his side can find a winning formula.

7. Liverpool vs. Manchester United

Two of England's biggest and most successful football clubs will renew their rivalry this weekend at Anfield in a thrilling clash that promises to see who emerge as victor. Fans eagerly anticipate this exciting matchup which could see regional dominance shift hands.

The 'North West Derby' is always a fiercely-contested contest between the two clubs and has seen them engage in fierce battles in previous meetings. With Liverpool unbeaten in five matches, they have an excellent chance to take home the trophy on Sunday afternoon.

Liverpool's recent home form has been remarkable, with three wins in a row at Anfield and 10 points from 5 matches. Additionally, they've kept 4 clean sheets in those five matches as well.

8. Chelsea vs. Tottenham

Chelsea face a formidable road test this weekend when they travel to Tottenham Hotspur Stadium in north London for their match against Spurs. After suffering defeat against Southampton last time out, the Blues will be eager not to repeat that result and secure an encouraging result against their London rivals.

Tottenham's team sheet remains unchanged from last week's 2-0 victory at West Ham. They still rely on Joao Felix and Kai Havertz's speed at the heart of their defense to get the job done.

But they will need more from their attacking players as the game draws near. Chelsea have lost five consecutive matches in the Premier League against Tottenham and it seems unlikely that will change this time around.

9. Newcastle vs. Manchester City

Newcastle are eager to rebound from their EFL Cup final defeat and prepare for an electrifying Premier League encounter against title-chasing Manchester City. At fifth in the table, Newcastle will look to put their recent poor form behind them in order to move closer towards reaching the top four.

Manchester City are unbeaten in their last five away matches and will be confident of taking all three points from this weekend's clash at Etihad Stadium. City's recent results in both FA Cup and EFL Cup give them plenty of motivation for victory, while Newcastle are looking to rebound from their disappointing loss to Tottenham last time out.

10. Chelsea vs. Manchester United

This weekend in the Premier League, Chelsea travels to Stamford Bridge to face Manchester United. This match is crucial for both sides as they look to extend their winning streak and make a statement in the race for the top four.

Since Graham Potter took charge, Chelsea have enjoyed a run of impressive victories. But they must overcome an Aston Villa side that is back to their best under Erik ten Hag.

No side has lost in their last three matches and each produced fewer than three goals in each of those contests, providing plenty of reasons to be optimistic about this matchup.

Kepa Arrizabalaga will be the key man on the field today, as he's been in superb form recently and should be the key man for Arrizabalaga to perform. Up front, Mason Mount and Raheem Sterling are expected both to start after missing the Brentford game due to injury.

Human Augmentation With Robotic Body Parts is at Hand, Scientists Say

Scientists are combining neuroscience, engineering and wearable electronics to create robotic body parts that could be controlled by brain signals. This could give people with physical disabilities greater independence.

Artificial intelligence (AI) is often touted as the technology that will eventually replace humans in many jobs, but a more nuanced view suggests AI could actually make us work faster and smarter by augmenting human workers with AI systems.

Robotic hands

Scientists believe you may soon be able to add a hand or arm to your body using the same technology that allows robots to walk and drive. This approach, which has already been tested by a designer and physiologist, would function similarly to how 3D-printed thumbs can be added to any hand.

Human augmentation is becoming more and more commonplace, so it's essential that users feel completely at ease using them as an extension of themselves. According to Fresh Consulting, this requires seamless integration into daily life and usage that's familiar for them.

Makin suggested that adding robotic parts to the human body could make tasks more comfortable and efficient for people with physical disabilities. She noted the technology could also be beneficial in other contexts, such as when waiters hold plates or electrical engineers solder wires.

Makin and her team are developing the MUlti-limb Virtual Environment, which would let users work with up to four lightweight wearable robotic arms they can simulate in virtual reality. Unlike current prostheses that rely on buttons or visual cues for movement control, the augmented body would utilize "thinking" instead.

Scientists at Osaka University are developing a device that allows people to gauge the grip of someone they're speaking with on videoconferences by shaking their hands. This prototype, known as a Robot Hand, utilizes pressure sensors that transmit grip strength from one person to another.

However, creating an integrated hand with the dexterity and other qualities of a human hand is no small feat. A number of actuation parts must be included, and their size and weight may make attaching it to an existing robotic arm challenging.

This study created a dexterous robotic hand with high degrees of DOF (dexterity of movement), strong grasping force, and payload that can be controlled easily. Furthermore, its cost was considerably lower compared to other currently available hands.

Robotic arms

Scientists have long been exploring robotic body parts, from extra arms and legs to fingers and toes. If these artificial devices can be programmed into a user's brain, there could be numerous applications in human augmentation.

People using powered wheelchairs might be able to control their prosthetics with a joystick, and those who have lost limbs may use robotic arms for holding and moving objects. Despite the obvious advantages of such devices, their ethical use in people with physical disabilities remains uncertain.

Researchers predict that humans in the future may use body parts in ways they cannot currently imagine. For instance, researchers at University College London asked a group of people to wear an electronic "third thumb," controlled with pressure sensors on their big toes.

Research results demonstrated that people's brains quickly adjusted to using the 'third' finger, developing an enhanced sense of embodiment over time. However, mild changes in representation of motor function in that hand after prolonged usage should be taken into account as caution should still be exercised.

Robotic hands are an increasingly popular solution in industrial and commercial settings, from gripping and carrying small items to holding and assembling heavy components. These 'hands' can often be programmed to carry out specific tasks like twisting bottle caps on food jars or tightening screws on automotive components.

They're typically equipped with an 'end effector, such as a drill or blowtorch, to suit the job at hand. These end effectsors are designed with an 'end-loaded' design - that is, they can support only so much weight before breaking down or being damaged.

A key characteristic of an efficient robot arm is its repeatability, or the ability to repeat a task repeatedly without sacrificing speed or precision. To achieve this goal, the 'end effector' must be programmed and memorised with specific movements in order to fulfill its intended function.

Other critical characteristics of a robotic arm include its number of axes--joints that allow it to make complex movement--and its working envelope or 'working space', or space where these axes occupy while moving. All these factors are taken into account when selecting one robot arm for specific production roles.

Robotic legs

Scientists predict that human augmentation with robotic body parts is near, but to make this work effectively, users must fully integrate them into their lives as an extension. A range of technologies is in development - including robotic hands, arms and legs that could aid those who have lost limbs or are paralysed.

Though recent advances have been made, robotic limbs are not yet widely used. Most people with amputations or paralysis use powered wheelchairs with an arm controlled by a joystick or other hand controls. However, some have mind-controlled prostheses that operate using their remaining muscles.

Robotic leg devices are commonly employed to treat spinal cord injuries, neurological disorders and strokes. They attach to a patient's existing lower limb structure and reinnervate muscle contractions, creating an artificial leg that functions similarly to one that would naturally occur.

Conventional robotic legs can help compensate for missing leg muscles, but they often lead to falls that send amputees to the hospital. According to researchers in Nature Communications, a new robotic prosthesis that functions similarly to a natural leg could reduce these falls by as much as 70%.

Researchers believe their strategy can work in the real world since it utilizes a control strategy that mimics how people's limbs respond to environmental changes. The result is a robotic leg which produces stable walking gaits on uneven ground and helps recover more quickly from trips or shoves than traditional prostheses do.

Though this approach is a positive step forward, it also presents several significant obstacles. First and foremost, robotic legs must maintain balance dynamically which is difficult with current technologies. Furthermore, scientists are working on finding ways to perform motion control & walking with minimal power consumption - another hurdle they are currently working to resolve.

Researchers at Carnegie Mellon University are striving to address these problems by combining their understanding of human joint dynamics during locomotion with robotics. Their goal is to develop a new class of wearable robotic technology that incorporates these discoveries into its design and controls.

Robotic feet

As more researchers consider human augmenting with robotic body parts, robotic feet are emerging as a promising candidate. Unlike hand-operated prostheses that use pressure sensors attached to the big toe, robotic feet use hydraulic or pneumatic pistons - similar to how muscles contract during normal walking that must be replicated for accuracy.

Like all motors, the movement of a robot leg requires intricate coordination. Scientists must figure out how all those pistons move together to produce an equilibrium-inducing walking pattern for its owner. Furthermore, they have to factor in environmental variables like gravity and other external influences as well.

An essential element of this process is an enhanced control system that syncs up a prosthesis with its wearer's movements, to prevent them from falling out of sync. Clode and her team stress how important this step is - especially for people with disabilities such as missing fingers or hands.

The team is working on a variety of devices, from an extra thumb to the ability to walk using a robotic ankle. The first prototype of these products is currently being tested at Cambridge's Media Lab - a glass complex on Amherst Street that houses cutting-edge research facilities.

Georgia Tech researchers have developed the DURUS bipedal robot to replicate human walking motion more closely than flat-footed robots can. This new style of walking is said to increase energy efficiency and allow the bot to traverse uneven terrain more effectively.

The robot can navigate a variety of curved metal pipes and flat surfaces thanks to its hybrid rigid-soft feet design, inspired by an inchworm's legs. This compliant foot has a stiff section with an electromagnet and soft toe covering for enhanced adhesion to pipes it crawls on. Furthermore, increased real contact area (RCA) between the foot and pipe increases brake and grip performance for various kinds of surfaces such as oil/gas pipeline inspection onshore.
