Researchers designed intelligent walking sticks with integrated navigation for people with visual impairment

the cane is designed to help users detect any obstacles on their roads and easily bypass them indoors or outdoors. One of the biggest benefits of the new enhanced walking stick is that it is significantly cheaper than the previous smart walking stick. Some smart walking sticks used to be very heavy, weighing up to 50 pounds and costing up to $6000

the new enhanced walking stick uses state-of-the-art sensors and weighs only 3 pounds. It can be made at home with free parts and open source software at a cost of about $400. The researchers’ goal is to build a portable walking stick for hundreds of millions of visually impaired people around the world

among the sensors used in walking sticks, there is a lidar sensor, which is used to measure the distance from obstacles to help users navigate around these obstacles. Other sensors include GPS, accelerometer, magnetometer and gyroscope. These sensors work together to monitor the user’s position, speed, direction and other data

walking stick also has its path finding and robot algorithm based on artificial intelligence, which is similar to synchronous positioning and mapping technology. At the top of the walking stick is a motorized omni-directional wheel designed to keep in contact with the ground. The wheel is an important part of the system and guides the user by gently pulling to the left or right around the obstacle. The integrated GPS function can guide the user to a precise location
