I got a Drift XR toy for $25 (including tax) which came out as a CVS's Christmas Seasonal Toy for Year 2023.

This one has 4 magnum wheel based.

What is impressive about this model is that it runs with only 1 rechargeable lithium-Ion battery of 3.7V and yet it runs very powerfully.

 

I like to modify this one with A.I. enabled self roaming rover.

The problem I noticed is that it runs too fast.

In order to make the computer vision stable, its speed must be reduced with PWM.
