The legs are retractable and are actuated by tiny servo motors inside the body. [Greg06] even included an ultrasonic distance sensor for the obstacle avoidance mechanism.

To do this, he used an ultrasonic sensor similar to, but cheaper than a Parallax Ping unit. Paired with an Arduino, the sensor triggers the fog machine’s pump for 20 seconds whenever anyone gets ...

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 ...

With the Arduino-based open source project looking for crowd-funding on the Kickstarter website, the AI robot kit has an integrated HD camera and ultrasonic sensor to allow it to recognise and track ...

Sparki uses an ATMega32 processor and a custom bootloader to run Arduino functionality. It has a distance sensor to calculate the distance to walls and objects, an accelerometer, light-sensing ...

Arduino-powered obstacle-avoidance cars made by learners at Karare AIC CDC school in Marsabit./STEPHEN ASTARIKOA quiet transformation is unfolding at Karare AIC CDC Primary School in Marsabit.In a ...

Sonair’s 3D ultrasonic sensor uses acoustic detection and ranging (ADAR) to enable 360° obstacle detection up to 5 meters. Each ADAR sensor offers a 180×180° field of view, allowing autonomous mobile ...

A new class of sensor technology dubbed ADAR (acoustic ranging and detection) enhances autonomous mobile robot (AMR) safety while offering 50-80% cost savings compared to traditional, LiDAR-based ...
