This study focuses on the development of an obstacle avoidance robot controlled by an ultrasonic sensor. The robot utilizes robotics and artificial intelligence techniques to improve obstacle ...

An ultrasonic sensor is used to avoid clash during motion.” Watch this video on YouTube . To build your very own Arduino robot jump over to the official Instructables project page for more details.

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.

One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a Linux computer. The end result is a virtual touchscreen that can be made at home.

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 ...
