Custom parts and enclosures

UV rover CAD file(MODE- 1)

There are two modes in this UV rover, in first the rover is without glass modification, in this if human contact presence is sensed by sensors it will automatically turn-off the lamp.

We have also uploaded our cad file and images on grabcad, so everyone can see it there in 3D viewer and download it too.

UV rover CAD file(MODE- 2)

There are two modes in this UV rover. In the second case the rover with glass modification, in this if human contact presence is sense by sensors, the glass will cover the UVC lamp so no harmful rays fall on humans and also turn off the lamp, providing double layer protection for humans from harmful UV rays.

We have also uploaded our cad file and images on grabcad, so everyone can see it there in 3D viewer and download it too.

LED Panel Circuit

We are also adding a UV LED panel below the rover, which will work as an additional disinfecting device, it will be attached below the rover and do extra cleaning of the surface with greater focus.

Code

Software 1

using raspberry Pi I2C communication with servo driver which sends signal to L298N- H bridge to control the movement of the rover and dc motors.

Software 2

This the web-based app to control the UV robot
