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 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 to recharge the battery. 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 food, customers have to enter the unique code provided for them by the company. This not only ensures that they pick up the right pizza, but also prevents the pies from getting stolen.
Scientists expect 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. ”
Owning a smartphone may not be as smart as you think. They may let you surf the Internet, listen to music and snap photos wherever you are…but they also turn you into a workaholic, it seems. A study suggests that, by giving you access to emails at all times. The all-singing, all-dancing mobile phone adds as much as two hours to your working day.
Researchers found that Britons work an additional 460 hours a year on average as they are able to respond to emails on their mobiles. The study by technology retailer Pixmania, reveals the average UK working day is between nine and ten hours, but a further two hours is spent responding to or sending work emails, or making work calls.
Almost one in ten admits spending up to three hours outside their normal working day checking work emails. Some workers confess they are on call almost 24 hours a day, with nine out of ten saying they take work emails and calls outside their normal working hours. Nearly two-thirds say they often check work emails just before they go to bed and as soon as they wake up, while over a third have replied to one in the middle of the night.
Ghadi Hobeika, marketing director of Pixmania, said:" The ability to access literally millions of apps, keep in contact via social networks and take photos and video as well as text and call has made smartphones valuable for many people. However, there are drawbacks. Many companies expect their employees to be on call 24 hours a day, seven days a week, and smartphones mean that people literally cannot get away from work. The more constantly in contact we become. The more is expected of us in a work capacity."
He will the challenge bravely.

Last Saturday I went camping with several friends. In the later afternoon, we put up our tent in the middle of a field. Then we cooked a meal over an open fire. The food smelt good. After a meal, we told story and played games by the camp fire. At the eleven o'clock we felt tired but we put out the fire and got into our tent. Lie in our warm sleeping-bags we slept soundly. At midnight one boy woke up and began shouting. The tent was full water! We got out of our sleeping-bags and hurried outside. It was raining heavy. A stream had formed in the field, that wound its way across the field and flow under our tent.
