to mark as completed I hope to explain this kit a little better than the current reviews. First off I chose this kit because it included a Raspberry pi 4 and a touch display.
The kit:
The tank kit itself is nice quality and the instructions and very good and in full color
I had an e-mail with a shared google drive a couple hours or so after I ordered it.
Lidar is of good quality and has LEDs built into it
( I tested every thing with a thermal gun and found nothing hot after running out a whole batt. "But there is room for heat sinks ")
The included batt. is 2200 amh. " It shows a much bigger batt. in the video. and states "Accessories shown"
Included sd card is blank. They will e-mail you the link to a google drive and you can burn your new sd card.
The app that this uses is their own and other Ros-Slam apps will not work. "Note: Customer service at XiaoR GEEK has been great!!!!" I've e-mailed several times and they have been great to work with sending me links, pics, files, etc...
{The app..... First, it's only for Andriod no ios. Second, they will send you the apk file but you need to figure out how to sideload it yourself... It's not in the play store. After much trial and error, I got it to install using a side loading program called "Solid Explorer" from the play store.}
So in closing, This kit has some good quality parts and there's good customer support but this is NO rtr r/c car. You will have to know a lot about programming, ROS, Slam, Apps, Apk, Linux, and,Electronics.
And there is a level of trial and error/Learning. The included book is very very good! And in English!!!
I was a little hesitant at first but again the customer support is good " And they have a nice way of telling you to "READ THE BOOK!" lol
