The Arduino microcontroller serves as the brain of the mower, processing input from the sensors and controlling the motors. Ultrasonic sensors are used for obstacle detection, ensuring that the ...

The concept behind this prototype is that any obstacle will be detected and a physical notice will be given to the wearer in real time. For the physical feedback, Denver has made some vibrating boxes ...

Ultrasonic range sensors can have varying fields of view. Some are around 15deg and some can be nearly 90deg. Multiple sensors mounted at different angles is superior to scanning for fast robots.
