How to make a surveillance robot using ESP32 Cam Module | Hash Robotics

Hello, humanoids...
In this video, I have made a surveillance robot using the ESP32 Cam module.

ESP32-CAM is a low-cost development board with a WiFi camera. It allows creating IP camera projects for video streaming with different resolutions. ESP32-CAM has a built-in PCB antenna.

It has OV2640 Camera Module 2MP For Face Recognization has a very competitive small-sized camera module that can operate independently as a minimum system with a footprint of only 40 x 27 mm.
It is suitable for home smart devices, industrial wireless control, wireless monitoring, and other IoT applications.

Kindly watch my other videos...

Your project is well designed for a prototype. A few observational comments: 1, loose the music and put in text explanations informing what you are doing especially in the code section. 2, Since both Arduino and the esp32 code libraries are open source and they do change over time some of your code will break and by the comments it seems to have. I had a problem in another video ( other creator) that was a few years old that the library he used was replaced by a different one. 3, There is an error in one of the photos in the zip file it shows 4 AAA batteries 6V rather than 3 Lipos @ 9v I doubt that AAA batteries can deliver the power for those motors.

The best tutorial which I have seen. Great thanks!

Hi, thanks sharing your project. I just want to draw your attention to the fact that there is a bug in your code on Google Drive. The IP address for streaming image is hard-coded in your HTML (app_httpd.cpp). But this is different for everyone else and cause an broken link error. Many greetings

Hello! Great project! How can I get the libraries? To solve issues such as: dl_lib_matrix3d.h: No such file or directory

Everything works for me except the servo control on GPIO2. If I call InitServo my camera will not initialise. The GPIO2 pin is meant to be available, provided you do not use the SD card. Any idea what is going wrong ?

EDIT: The problem appears to be the way that ESP32 pwm channels share clocks. Each channel consecutive channel pair need to use the same clock frequency. Also on my board (Ai Thinker), channels 8 and 9 do not appear to work. Also, as far as I can see, the LED flash on channel 7 should clash with LMotor2 on channel 6.

hi,
Do you have other video explainning how to make the code? I would like to undertand who to make my own functions.
thanks

An amazing project! Is it possible to put a rechargeable battery and know the battery level, when the battery is low go to a charging station? Or it would not be possible because it has to be turned off to recharge? Thanks genius!

Hi! Just curious. Where does the html which makes the buttons and positions/sizes the camera display resides in the .ino code? Is it part of one of the libraries? Great project!!! Subscribed!

[DUGGYMUSIC]

Doesn't it work with 6V batteries(1.5V x 4)?
Does it have to be 12V?

good robot! How could I add another servo that rotates from 0 to 180?

I am making this robot as home security system with additional sensors but since this cannot be operated from anywhere what can its application be, please help me

[Projectswithmani]

hii
can I use the connections for arduino uno instead of USB module???

[vallapureddynithinreddy]

From how much range(distance) can we operate and can we operate when there is a wall like obstacles?

[Burgyste]

Super project thank you, could you please make the same project replacing the L298N Bridge with a TB6612FNG H-Bridge or DRV8833, that is a new wiring plan and new code.

@hashrobotics and when i am trying to set the proper settings i am not geting any selection options in the programmers place

Great project. Is it possible to add a label with a sensor value on a web page? If yes....how I can do it?

[CristianDv]

where is the library of dl_lib_matrix3d.h i can´t find, please help

I HAVE A QUESTION, I CANNOT FINTHE AVR ISP IN THE PROGRAMMER, HOW CAN I INSTALED IT?
