Saudi GACA orders new announcement made for passengers after full restoration of flights

Scientists at Stanford University have incorporated automated technology into the blind. It also has a wheel that increases the speed of walking in blind people.

The rod works with light detection and ranging (leader) technology, which is the heart and brain of a smart rod, allowing the rod to look around and alert the owner in the event of an obstacle.

When it was tested on blind people, their walking speed also increased by 1% because there is a horizontal wheel on the edge of the stick that keeps moving left and right. Although priced at 400 400, the low cost could benefit 250 million people worldwide who are completely or partially blind.
Mechanical engineer Patrick Slade said he wanted to make his invention more than a simple stick. Our invention not only warns of an obstacle but also tells us how to avoid the stone or table in front of us.

The smart rod has a gyroscope, accelerometer, GPS system, magnetometer, and laser system. All these sensors together keep the rod informed of its position, speed, direction, and various objects around it.

The Smart Stick also includes a variety of algorithms, including localization and mapping at a time. It instantly makes a map of the surroundings, showing where the human being is in it and how to take his path.

“As far as we can, this stick changes its course when it sees an obstacle, and its wheel turns and brings the blind person on a clear path,” says Michael Cokenderfer, a computer scientist at Stanford University. If the person with the cane calls it a library or tea shop, the cane turns it left and right and takes it there by itself.

Although the design is open source, it costs 400 400 with hardware
