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.

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

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.

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

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 ...

Open-source robot project Qbo has gained a new set of sensors, in the shape of a custom ASUS Xtion tiara that allows the 'bot to 3D map his environment, autonomously navigate and – most ...
