Wall-E support for SR04

thingiverse

Here are three DIY hacks that bring an HC-SR04 ultrasonic sensor to life, much like the beloved Wall-E robot. For project one, start with a base unit constructed from wood or 3D printing materials, adding two wheels made from plastic or PVC pipe and some durable bearings. Mount the HC-SR04 ultrasonic sensor in such a way that it faces forward and includes an arduino nano controller. Project number two incorporates servo motors that provide precise control for movements like tilting or swiveling the ultrasonic sensor unit back and forth while scanning its surroundings. Make sure you use wires insulated against heat as well. A rechargeable battery pack serves power. For project three, design an advanced robot using acrylic and cardboard. It includes three ultrasonic sensors mounted on movable arms that provide depth readings when interacting with nearby objects. Program your controller to display warnings in the case of low-battery warning and nearness alerts when things come close to the HC-SR04 units mounted in a circular array configuration around the center hub area where other electronics are housed as well as additional sensor input options
