DIY WiFi Controlled Pesticide Spraying Robot Kit for Smart Agriculture | IoT Based Robot using NodeMCU & Arduino

Build your own Smart Agriculture Robot that sprays pesticide automatically using WiFi control! 🚜💧
This DIY project helps students and hobbyists understand how IoT and robotics can make farming more efficient and safe.

The robot is powered by a NodeMCU (ESP8266) and can be controlled wirelessly through WiFi. It carries a mini water pump to spray pesticides or water, and runs on four BO motors for mobility.
Perfect for school exhibitions, engineering students, and STEM robotics learning focused on smart agriculture.
