Build your own 3D printed DIY FPV mini robo tank using Seeed Studio XIAO ESP32S3 Sense

Hey everyone welcome back to an interning blog today we are going to build awesome FPV Robo tank using Seeed Studio XIAO ESP32S3 Sense, which can be controlled using local server based remote controller.

read this complete blog and you will get detail information on how to build this awesome Robo tank.

So, without any further delay let’s get started

Let’s start with

Seeed Studio XIAO ESP32S3 Sense

Seeed Studio XIAO ESP32S3 Sense is powerful board similar to Seeed Studio XIAO ESP32S3  but this sense model has OV2640 camera sensor module which is detachable which enable the use of this board in application such as image processing, Video Monitoring, and many more and other feature are similar to Seeed Studio XIAO ESP32S3 you can read more about these board on seeed studios official website

Download the STL file from above GitHub link which contain all the STL file 

Upload it to slicer of your 3d printer place the print proper on plate select the proper infill and other setup and slice it

Convert it to G code

And transfer the G code to SD card

And insert the SD card into to the printer

Power on the printer

3D print will start

Wait till completion of print and remove the prints after completion

3D print on robu.in

If you do not have 3d printer or you are unaware of 3d printing technology

No worriers

You can place 3D printing part order on robu.in 

The process is simple

You just need to upload STL files of 3D print one by one select the infill, material, color and quantity and add it to cart after add all file check out pay and order will be placed

Refer this blog for detail process - https://robu.in/iot-pulse-oximeter-seeed-studio-xiao-esp32c3-max30102/

Circuit design

Components assembly

Connect all the components as shown in circuit design above

Provide supply to driver for motors and supply to board from 3.7 LiPo battery

Code

Compile and upload the given code in S3 sense board

Full code on :- https://github.com/Robu-In/FPV-ROBO-TANK

Before uploading select the proper board from bord manager Provide the name and password for connection

app_httpd.cpp

After uploading the code connect your device to Robo tank name and password will be same as you mention in code once the device is connected open your browser and print the IP which is displayed on serial monitor 192.168.4.1 and control panel will be open with camera stream.

Final setup

Now its time for final assembly let’s build the 3d Robo tank model and place all the component in it accordingly

image is given below for reference

Use double sided tape or hot glue to place and fix the component on there places

Connect your device to   

Tank take the control and Drive

Conclusion

That how we have made this FVP Robo tank which is control using server control panel and which provides Live stream we can improve the speed by using high RPM motors and powerful batteries.
