A small robot may help children who are recovering from long-term illnesses in the hospital or at home. These children may feel isolated from their friends and classmates. The robot takes their place at school. Through the robot, the children can hear their teachers and friends. They also can take part in class from wherever they are recovering.
Anyone who has a long-term illness knows that recovering at home can be lonely. This can be especially true for children. They may feel left out. Now, these children may have a high-tech friend to help feel less lonely. That friend is a robot. The robot is called AV1. AV1 goes to school for a child who is homebound while recovering from a long-term illness. And the child's school friends must help. They carry the robot between classes and place the robot on the child's desk.
A Norwegian company called No Isolation created the robot. The co-founders of No Isolation are Karen Dolva and Marius Aabel. Dolva explains how the robot AV1 works. She says, from home, the child uses an iPad or a phone to start the robot. Then they use the same device to control the robot's movements. At school, the robot becomes the eyes, ears and voice of the child.
So, it sits at the child's desk in the classroom and the child uses an iPad or a phone to start it, control its movement with touch, and talk through it.
The student can take part in classroom activities from wherever they are recovering — whether at home or from a hospital bed. The robot is equipped with speakers, microphones and cameras that make communication easy.
Certain activities can be good or bad for our brains, so let's see which of the seven habits you should carry on doing or give up.
Sitting still When we sit for long periods (more than three hours), our inactivity decreases the blood flow to the brain and the oxygen supply. This decreases brain activity in the part of the brain we use for thinking, organizing and decision-making. Action: Relax the brain by getting up to stretch and move around every 30 minutes. |
Staying curious Learning new skills leads to better understanding - the brain's ability to form new connections between existing neurons(神经元). Action: Why not take up a musical instrument or an evening class? |
Fast food The quickest way to jam our brains is to fill our bodies with fast food. Too much salt leads to more brain illnesses. Action: Eat fresh and green food as much as you can. |
High-quality sleep Studies have shown being deprived(剥夺)of sleep for 24 hour decreases memory and concentration. But regular, restful sleep improves memory. Action: Try and go to bed before midnight and aim for 7-8 hours' sleep. |
Being overweight Obesity does great harm to the brain and is also a risk factor for cognitive(认知的)decline. Action; Try to lose some weight if you are too fat |
Drinking alcohol regularly Regular drinking lowers the levels of serotonin (血清素) in your brain and can make you depressed. Action: Many medical experts recommend taking regular days off from drinking to ensure you don't feel sad and don't become addicted. |
