ELEGOO TUMBLLER ROBOT - THE BEST SELF BALANCING ROBOT !!!

I bought this robot from Amazon.co : www.amazon.com...
I consider this robot the best self balancing robot!
I have couple other robots that you can find here: • Self Balancing Robot Z... that do not do everything it should!
My friend Hari Wiguna www.youtube.co...
is trying to finish the sketch (code) for the robot, because it doesn't work with the phone APP. There is missing code inside the sample you can find in my video: • Self Balancing Robot Z...
But this robot, if you do what the manual instructs you to do, will work right out of the box!
I hope you'll have as much fun as I did.
