What Do I Build Next? A StereoPi Based Tank Vehicle

What Do I Build Next? It's been awhile since I last published any project. I have started many projects and experimented with the Nvidia Jetson Nano, the Atomic Pi and even the Raspberry Pi 4 with 4gb. I make most of my purchases from Amazon, and back projects on Kickstarter, Indiegogo, and CrowdSupply.

Last Christmas, 2018, I published a Sony Spresence based robot:

so this Christmas, 2019:

I looked and purchased a few Donkeycar style kits for artificial driving abilities for the RPi 4 ( https://www.amazon.com/XiaoR-Geek-Starter-Platform-Raspberry/dp/B07VBQKZB2/ref=sr_1_1_sspa?keywords=donkey+car&qid=1573602339&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyT1pPSEZBQVhIVTBFJmVuY3J5cHRlZElkPUEwNTM4ODk5M1I2VjRESUJUTUlRRSZlbmNyeXB0ZWRBZElkPUEwNDUxMDE1Mk1JOTBHQzJDREEySCZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU= ) and Jetson Nano ( https://www.amazon.com/XiaoR-Geek-Starter-Driving-Platform/dp/B07TZ449VP/ref=sr_1_1?keywords=donkey+car&qid=1573602302&sr=8-1 ); and FPV video streaming builds based upon Kookye/Osoyoo/Adeept kits and knowledge. I looked into Arduberry's Arducam ( https://www.amazon.com/gp/product/B01ESRYA2Y/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 ) and Arducam ( https://www.amazon.com/gp/product/B012UXNDOY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 ), Google's Vision, and Pixy2 pan-n-tilt assembly ( https://www.amazon.com/gp/product/B07D1CWJTV/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 ) and Pixy2 ( https://www.amazon.com/Charmed-Labs-Pixy2-Vision-Sensor/dp/B07D1CLYD2/ref=pd_bxgy_img_2/147-6700668-9160725?_encoding=UTF8&pd_rd_i=B07D1CLYD2&pd_rd_r=6ac42d3c-1254-43ee-aa04-457cce61204e&pd_rd_w=GadDU&pd_rd_wg=lSHft&pf_rd_p=09627863-9889-4290-b90a-5e9f86682449&pf_rd_r=YTS045WR3D60FHGBKCX7&psc=1&refRID=YTS045WR3D60FHGBKCX7 ).

Please don't be alarmed by the above links, ultimately I used/reverted to simple and common hardware and reused some Raspberry Pi video streaming and python code for the DC motor control.

I had wanted to add the StereoPi assembly onto my last "What Do I Build Net?" project, but that "Frankenstein Build" already had too many individual software interfaces involved.... I was going to place this onto the Robot claw for "fine positioning"

First I assembled, configured and tested the various StereoPi software packages, in hopes to incorporate Robot Stereo Vision. I followed Wiki, posts and forum info from:

https://wiki.stereopi.com/index.php?title=Main_Page#StereoPi_Wiki_Main_Page

Here are pictures from the StereoPi build process: 1st unpacking

Here are pictures from the StereoPi build process: 2nd assembly and test

Here is my "camera determination video"

Secondly, to build the tank chassis:

Assembly of the roller wheels...10 of them...and 2 cogged drive wheels

Roller wheels

Assembly of the cogged drive wheels:

Assembly with aixles and hubs

Attachment of wheels to chassis sides

Attachment of DC Motors and Drive Coggs to side chassis

Attachment of treads to chassis

Temporary attachment of battery holder

Kookye Demo Tank Build

Referring to a previously published project for software updates:

StereoPi/RPi DC motor control DEMO

Interconnect and wiring the StereoPi Robot

Christmas Morning, 2019, it's been awhile since I last visited this project. I realized that I hadn't uploaded "Mobile Tank Video" demo

I need to revisit stereo streaming under robot control, that was lost after an "apt-get update"... but still The robot does drive. Note: I have extra, unused wires from motors that need cable management, battery and connectors as well.

I needed to extend video camera cables to incorporate pan-n-til servos as well: (pan-n-tilt code will be incorporated in a later software update)

As a starter for software and control of this project, I followed these useful links and guides:

These Available Guide(s) were consulted studied and expanded upon to build previous multi-track tanked vehicles:
