Sonair’s 3D ultrasonic sensor enables 360° obstacle detection using acoustic detection and ranging (ADAR) for safe AMR navigation.

Honestly, if it weren’t for the ultrasonic distance sensor protruding from the spherical body, you might think that the entire robot was just a little Wiffle ball.

The DIY robot vacuum cleaner is equipped with what seems to be an array of ultrasonic sensors for navigation and is powered by an Arduino Mega-development board, attached to a HC-05 Bluetooth ...

The build relies on the classic Arduino Uno microcontroller, which talks to a HC-SR04 ultrasonic sensor module and two infrared sensors in order to track a human target and follow it around.

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.

The first orders are already in place and the groundbreaking sensor is on track to achieve safety certification, an industry-first for 3D ultrasonic sensing in air.
