The chassis I used was the popular "4WD Robot Car Chassis", which is economical and practical since it has two platforms, 4 gearmotors, 4 wheels, and enough holes to mount the devices of our design.

How to assemble this kit?
Assembling autonomous robot, recommendations:
- On the lower platform mount: Battery, gearmotors with wheels, L298N driver, power switch, and IR distance sensors.
- On the upper platform mount: Battery, Tesla coil, UV Lamp, Relay, Arduino and ESP32-WROOM-32 boards, and the ultrasonic sensors.
- On the top platform add (Not in Motion Version): Raspberry Pi and Arduino Pro Mini boards, rasperry pi camera, and reflector with servo.
- I used 22 additional screws to the ones in the chassis kit.
Now, I show you the parts assembled with their sensors mounted on the 4WD Robot Car Chassis in the figures below:
