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.

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.

That's just what I need. I will study more about that items.
