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

[@petermenningen338]

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!

Fantastic robot car! 😀👍

Excelente, mil gracias por compartir tus conocimientos. Un saludo desde Bogota-Colombia

[@HashRobotics]

thank you.keep supporting

[@f.schwemberger3359]

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

[@Paul-rs4gd]

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.

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

[@ra198582]

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

[@dreizehnzd5334]

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

[@rohanraj5435]

Define an another servo in .ino or .cpp file

[@rohanraj5435]

It will be easy if you know the arduino language and c++ language

[@DUGGYMUSIC]

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

[@rohanraj5435]

It works only on 12v battery or 11.1 battery approximately

It is not used in the latest ESP32 support from Expressif, and has been removed. You can try to install v1.02, that version is meant to work although I have not tried it.

[@vallapureddynithinreddy5321]

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

[@JanneOksanen]

I think it's a web server running on the ESP32 so basically as long as the robot and your control device are connected to the same network you can control it from anywhere in the world. It just depends on how good the wifi coverage is around the robot.
