What's more exciting than having a fresh hot pizza delivered to your door? How about having it brought to you by a robot? Thanks to Domino's Robotic Unit or DRU, that just became a reality! On March 8, the three-foot tall robot delivered its first pizza to some lucky residents in Brisbane, Australia.

    The fully autonomous DRU is the result of a cooperation between Domino's Pizza Australia and Marathon Robotics.The 450-pound machine that travels at a maximum speed of 12.4 miles an hour can traverse a distance of up to 12 miles and back, before requiring a battery recharge. LIDAR, a laser-based sensor technology similar to the one used in self-driving cars, enables DRU to detect and avoid obstacles, while traditional sensors, much like those used in vacuum robots ensure its path is safe as it heads to its destination.   

    The robot can fit up to ten pizzas and even has a separate cold area to accommodate drink orders.To access their fond, customers have to enter the unique code provided by the company.This is not only ensures that they pick up the right pizza, but also prevents the pies from getting stolen.

    Scientists expert additional DRU's to be ready for service in their various Queensland locations within the next six months. But don't expect these super cute robots to replace humans anytime soon. According to Domino's the DRU still needs extensive testing, which the company believes could take up to two years.

    And then there is also the issue of regulations.The public use of autonomous vehicles is still banned in most countries.But Don Meij, the CEO and Managing Director of Domino's Pizza Australia New Zealand Ltd, is not worried.He is “confident that one day DRU will become an   integral part of the Domino's family.”

Hobbies Help Cure Addiction to the Internet

    While some parents have expressed concerns about the amount of time their children spent surfing the Internet during the summer break from school, it wasn't a problem for Yin Qiming.

    Instead, the 37-year-old Shanghai resident and his daughter divided their vacation between cyberspace and the 8-year-old's other interests.

    “My daughter has many hobbies and I and her mother respect her choices, so we accompany her to classes she enjoys, such as learning to play the drums and drawing,” he said.

    “She loves to play outside with her friends, so she doesn't think the Internet is a must-have thing in her life.”

    Yin added that he rarely imposes a time limit on his daughter's online activity.

    “She sometimes uses WeChat (a popular instant-messaging tool) on my mobile phone, but only to contact her mother,” he said. “Once she has her own plans every day and realizes that the internet is just a part of life, she won't become addicted to it.”

    Li Lin, a primary school teacher from Liaoning province, expressed a similar opinion.

    “We do some homework online, including reciting stories, and the children use the Internet frequently every day of their lives,” she said, noting that the children's online activity is limited to 30 minutes a day at school.

    “We should make better use of the Internet to provide children with more knowledge and help them to grow up,” said Li, who has a 10-year-old son.

    The key to preventing children, especially those at primary and middle schools, from becoming addicted to the Internet is to limit the time they spend online and to ensure that they know cyberspace cannot replace traditional forms of communication, she said.

    Mao Feizhu, a psychologist from Fujian province in southeast China, said people overestimate the influence of the internet.

    “Many people, even some parents, believe the Internet plays a big role in our daily lives, and many things can be completed online, but that's not completely right,” she said.

    “We can use social applications to talk or play basketball games, and even share what we are thinking about, but sometimes it's impossible for our emotions to be accurately reflected in this way. What children need is emotional communication and real physical exercise. After all, love cannot be bought on the net,” she said.

    Perhaps, the best way to stop young netizens spending too much time online is to encourage their other interests but also accompany them when they go online: “We should use the Internet, not become its slaves.

    Google's new camera, called Clips, is a small, smart device. It comes with a case that has a clip (夹子)，but it's not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photography out of your hands so it can capture moments on its own.

    This roughly 2-inch by 2-inch camera, with a three-hour battery life and Gorilla Glass for toughness, is intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smartphone.

    Onboard the Clips device, it uses machine learning algorithms (计算程序) to help capture scenes. Those algorithms include face recognition. "Once it learns that there's a face you see frequently, it'll try to get nice photos of those faces," said Juston Payne, the device's product manager. And they also want it to recognize facial expressions, which involved "training it to know what happiness looks like". The Google team also trained it to recognize what not to shoot — like when a child's hand is over the lens, or if it is tossed in a dark purse.

    The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing.

    Were people concerned it could seem strange? Yes, Payne admitted. But they said they addressed that by making it obvious what it is. A green light on the front signals that it is on. Besides, unlike a camera meant to monitor your home, it is not connected to the Internet.

    "This product is only possible because of the way that silicon has advanced" Payne said, noting that it was only in the past year or so that they could squeeze the technology down into a device this size. Going forward, we're likely to get more assistance from the artificial intelligence packed into our apps and gadgets.

    A Latin phrase beloved by every old-fashioned British schoolmaster was mens sana in corpora sano—a healthy mind in a healthy body. Greater physical activity is associated with better mental, as well as physical health. And it might also be linked to greater worker productivity, and thus faster economic growth. That is the conclusion of a new report from a European think tank — RAND.

    The RAND study looks at different measures: absenteeism (when workers take time off for illness) and presenteeism (when they turn up for work but are less productive because of sickness). The latter measure was self-reported by employees, who were asked whether their work was negatively affected by health issues. The survey suggests that between 3 and 4.5 working days each year are lost as a consequence of workers being physically inactive. This is between 1.3% and 2% of annual working time. Most of this was down to presenteeism.

    Another potential gain from improved fitness is reduced health-care costs. In America, where health care is often provided through employment-based systems, firms could benefit. RAND estimates that total American health savings could be $6bn a year by 2025. But the study's authors conclude that if people met certain exercise targets, global GDP could be around 0.17-0.24% higher by 2050. Nothing to laugh at in a world of slowing growth.

    How to encourage workers to become more active? Rewards are useful but only if they have conditions; giving all employees free gym membership does not seem to work. Another RAND Europe study examined an experiment in which workers were each given an Apple watch, payable in instalments (分期付款) at a discounted price—but only to those who agreed to have their physical activity monitored. Monthly repayments depended on how much exercise they took.

    The problem is that many people are too optimistic about their health, ignoring the risks they face. This means that participation in workplace exercise plans tends to be low, around 7% in the sample studied by RAND. Firms are not the only ones that can encourage a healthier lifestyle; friends and families are likely to be more important. But businesses can play a bigger role.

    If RAND is right, this may bring them financial benefits. Company taskmasters may yet grow fond of an adapted saying: mens sana in corporate sano.
