TRASH-COLLECTING ROBOT / ESP32 APPLICATION
Trash Collecting Bot
A remotely controlled waste-collection robot built around an ESP32 and a Blynk mobile interface. The prototype combines a four-wheel drive base, servo-operated arms, a collection bin, and a metal-detection/sorting concept to help reduce direct human contact with collected waste.
About this project
About this project
A four-wheel chassis with a bin in the middle and servo arms, driven from a Blynk phone screen over Wi-Fi rather than by any autonomy. Two BTS7960 modules split left and right motor groups, three servos handle grabbing and dumping, and a metal or inductive sensor sits in the sorting concept. Power comes from a 12 V 4 Ah lead-acid battery through an XL4016 buck converter, with a warning not to feed motors from the board's 3.3 V rail. Buttons are labelled Grab, Collect, Release, Check, Initial Position and Dump, plus a dustbin toggle and a slider, but the exact virtual-pin mapping lives in the sketch and Blynk template. It is an educational prototype and should not touch hazardous waste.
