Build an ESP32-CAM Robot Car

[@Dronebotworkshop]

Hi everyone - It's come to my attention that there has been someone masquerading as myself, responding to some comments here with a link to a Telegram chat to win a prize from me. THIS IS A SCAM, I am not holding a contest, nor do I have a Telegram account. PLEASE DO NOT RESPOND TO THESE MESSAGES!! It's happening on a lot of my videos, I'm taking steps to remove them manually, but as I have 162 videos, it will take some time. If you do run across a suspicious comment, I would appreciate you letting me know at [e-mail]. Thanks! Bill (The real one!)

I've just realized that I haven't seen a 3d printer on this channel. I feel like this channel would benefit greatly by getting into 3d printing. It quickly makes everything a nail to it, the hammer for small projects. Need a project box? 3d print it, and add a custom cutout for a screen and maybe a camera or encoder too. Need a gear set? 3d print it, and for low speed applications it'll do just fine (and even medium/high speed with the appropriate bearings/lube) Need to make a latch system? 3d print it. Want to make a stand for that thing that's shaped weird? You guessed it. One of the greatest things is how quickly you can go from idea in your head to physical thing in your hand of relative high quality. Of course there's still a place for manual assembly of physical components, but for projects like the ones featured on the channel, you could slap a 3d printer in all over the place. It doesn't even have to be features, it could just be useful for setting up demonstrations. Just a suggestion I think would be an awesome addition to this channels arsenal.

[@sumantakumardutta986]

I fully agree to your opinion.👍

[@hrithikhu]

No one can replace your channel in terms of explaining stuffs. Thanks for being so great and motivating small hobbyist.

[@3DShe]

Hello Shaw, It seems you know about the video content... May I ask you to help me know all the names of all componentes needed to build this project?

[@hrithikhu]

@@3DShe do you want take my test ? BTW not interested in your stupidity. Thanks

[@paarthsstudio]

@@3DShe sure, esp32 cam, antenna, tb6612fnd MOTOR DRIVER MODULE, Flashing LED, 2xli-ion holder, 2 x 18650 li-ion abtteries, dc boost converter, ftdi adapter, dupont cables, dc geared motors, castor wheel and a frame

[@r_s_steam_cr]

Usted es genial!!! No solo porque comprende la lógica, sino porque su manera de explicarlo todo es muy sencilla y fácil de comprender. Cuando inicié en el mundo de los arduinos, su canal fue uno de los primeros que encontré, y desde entonces tiene un seguidor. Saludos. Ricardo.

[@BeefIngot]

Really small technical note: The 18650s are not lipos, but lion batteries. The difference is you can let a lion get down to 2.5v whereas the same voltage for a lipo would severely harm the battery.

[@leglessinoz]

What you're calling a lipo is still a lithium-ion battery. In a standard Li-ion battery, the electrolyte is a liquid while in a Li-ion polymer battery it's a polymer.

[@logicfacts9964]

I have 4 such modules and there is no any issues with camera quality. If you have problem then run camera demo and manually adjust camera focus by rotating plastic part that holds the camera lens. Also dont forget to remove the protective film at first

[@tubeDude48]

I have had the same base with motors for a couple of years, but did nothing with it. I guess I'll build one now! Thanks Bill.

[@Dronebotworkshop]

My apologies for taking so long to get this video out, I'm "breaking in" some new equipment and the recording didn't go as smoothly as planned (which is an understatement LOL)! Two broken cameras and a couple of power failures didn't help either. There are also a few audio glitches due to a loose cable that I have tried to correct as best I can, however, I didn't want to wait any longer to release this. Thanks for your understanding.

[@philgo2024]

You don't have to apologize, you always offer us good quality content, we can imagine the time it takes to you, nothing necessarily goes as planned, it's just life ...

[@retrorocketman6969]

Thanks for using your time to educate everyone in robotics. I have had a little difficult time finding a video that is clear and to the point. Speaking of video, the quality and clarity is perfect. The affordability of the esp32 cam has sparked my interest in robotics. I would like to use the facial detection to make a device that will recognize a individual and speak there name in a sentence. Such as a simple greeting. Would it be difficult to incorporate that into the code? Could you make a video on that subject if you haven't already. Thanks for the awesome work!!

[@TriggerThat]

About the the camera quality. You can buy replacement cameras for $4. You can cameras with wide or zoom lens and some even have longer ribbon cables to overcome the board positioning issue.

[@ermakers1297]

Built something similar using a L298N motor driver and a Tamiya tank base. The big advantage with the L298N is that is has a 5V regulator built into the module so there is no need for the buck boost converter. Supply power to the motor driver and it outputs 5V at upto 500mA which is more than enough for the ESP module. Simplifies the design and reduces part count significantly. The L298N is a big larger though, but it can also handle higher current loads if needed.

[@pippaknuckle]

The soldering to enable the external antenna on an esp32 is really hard. It's so tiny. Shame they didn't just make a jumper for that. Come on Expressif!

[@Ouchie]

I always got the "Brownout detector was triggered" error with the esp32 cam and couldn't fix it. Anyone else with the same problem?

Just a quick note: the article link in the video description appears to be incorrect: the URL ends with "esp32cam-car" (which opens a 404 Not Found page), but the real link ends up with "esp32cam-robot-car/". On the plus side, I got to browse through your excellent web site a bit more, so maybe it's a plus :)

[@RoyvanLierop]

"Using 7.4V to drive the motors" is incorrect as the NMC-based lithium-ion 18650 cells have a voltage range of 3.0Vup to 4.2V.So you're powering the motors with a variable voltage of 6.0 up to 8.4V. Your system also lacks undervoltage protection (Cells die

[@WagonLoads]

I am reposting this in the main list so everyone can respond.. I am trying to design a circuit board for this, but I am not sure if something is wrong here. I want to add an i2c device, so I can control extra servos and things.. What pins do I use for i2c that is compatible with the rest of this circuit? It looks like you are using the RX/TX pins for the same pins I think is used for i2c.. I can't find any reliable sources about this.

[@cbasmadjian]

@DroneBot Workshop, I clicked on your article to your website listed in the description and it states "Page Not Found". Any chance you can fix the broken link? Would like to read about this in more detail. By the way I am really enjoying your videos. I am a newly subscribed member. Great content.

You can definitely use ngrok service and port forward it to the ip address of the robot car and the port of the Web interface which is port 80

Hello. Thanks for this project. May I ask you to upgrade this project by adding a ESP32-based remote control? I found 2 interesting devices, fit for the rmote function. First is WT32-SC01 plus LCD touchscreen with ESP32 S3 onboard and several extra pins, sdcard etc. Is it possible to transfer video from ESP32 cam to that device and create there several buttons on the touchscreen for controlling car movements? The second interesting device is T-deck (also uses latest ESP32 controller, having touchscreen and even trackball for controlling movements).

Great video, I'm currently working on getting a IKEA KALLAX modified to hold my PS5, and I was going to try and use some simple relays to control a couple of computer fans to provide ventilation, but that TB6612FNG module looks like a good fit, with the benefit of providing some speed control.

Bill, as always, great content! I was looking for a reason to get one of those ESP32-CAM modules.

Did about a hundred of them and learned a ton doing so ... I'm sure your viewers could appreciate some box design / PCB mounting tips. it's easy to use some proto boards ... it's hard to plan the inside of a box, get the switches or pots connected in the box (learning about the basics of component mounting in a box) ... that would make a boring, but oh so useful video... I'm almost certain you could make any topics interesting anyway!! Thanks again for all your hard work, sorry for your lost friend too, it's bad enough to be losing someone you care about, worst when we cant see each other.. #CaVaBienAller right? :P

depends on how you make the box. you could reuse metal boxes. Or you could make them from wood, acryl glass or 3d print.
