Robots have taken over many of America's factories. But can they pick a strawberry? "It's really hard for robots to match what humans can do," says Bob Pizter, an expert on robots.
Any 4-year-old kid can pick a strawberry, but machines can't seem to figure it out. Pizter says the hardest thing for them is finding the fruit. Pizter's strawberry-picking robot is rolling into a strawberry field. This well-designed device drives itself. It's as big as a bus, long enough to straddle (跨越) a dozen rows of strawberries at once. Powerful computers are sitting on top. Underneath, there are high-definition cameras to find the berries, and robotic claws ready to pick them.
"Nobody's telling it what to do," explains Paul Bissett, the chief operating officer of Harvest CROO Robotics. "It's remembering its path down the row. It's remembering where all these plants are." It knows all this, thanks to the super-accurate GPS. Its computer brain contains a map showing the locations of every strawberry plant in the field. The action of machinery is truly impressive, but the baskets are still practically empty. Pitzer says the robots are able to find and pick more than 50 percent of ripe berries. That's not yet up to human standards. A typical worker, he says, manages to pick anywhere from 60 to 90 percent of the berries. Also, he admits, the machine is slower than human hands. On the other hand, it has some advantages. It can work right through the night. Two years later, he says, this machine will be in the fields working for real. "There are weaknesses to work out, but it's getting there. We're close." he says.
Strawberry companies are putting millions of dollars into this project. The reason, Gary Wishnatzki, the owner of Wish Farms says, is that it's getting more and more difficult to find enough people to pick his berries. "The fact of the matter is, if we don't solve the problem of this labor shortage with automation, the industry is facing a big challenge ahead. The price of fruit is going to be much higher," Jose Santos, the leader of the farm, says.
Jose is pretty convinced, though, that picking strawberries will always require people. The machines will break down, he points out. In fact, he's looking on the bright side. "You could afford to give people a day off if you have machines behind you,”" he says.
To forgive is a virtue, but no one has ever said it is easy. When someone has deeply hurt you, it can be extremely difficult to let go of your hate. However, forgiveness is possible, and it can be surprisingly beneficial to your physical and mental health. People who forgive show less sadness, anger and stress and more hopefulness, according to a recent research.
{#blank#}1{#/blank#}Try the following steps:
Calm yourself. {#blank#}2{#/blank#}You can take a couple of breaths and think of something that gives you pleasure: a beautiful scene in nature, or someone you love. Don't wait for an apology.
