Remote control carrier tracker following 1

[mingki]

Hi I need to make this electric cart to follow me around at a certain distance which could be adjusted.

The video shows remotely controlled electric cart and I want this cart to follow me like the one in the picture below.

The robot follows the wearable tracker.
Could you tell me how to build this kind of tracker unit?
If there is a commercially available complete item that I can purchase, that would be the best.

How closely do you want it to follow? How accurate must the distance be?

The minimum distance is 1m and the maximum distance is hopefully 10m. Less than 10m is also fine.
For the accuracy, i don't have a specific target in mind. As long as my electric cart follows me at walking speed (3.5km/h ~ 5km/h), I would be happy.
Thank you.

I suppose one could also wear some unusual color and apply machine vision with a camera to follow it. I got one called the Pixy 2 that can be trained for such things:

Thank you very much Dave.
That's just what I need. I will study more about that items.
