Hi, I have already posted a similar topic in December and with few adjustments it worked.. outside (it was based on GPS).
What I am asking now is if there is a way to make an Arduino robot follow you everywhere, outside and inside, for example using WiFi or Bluetooth, but I think that is more complex..! (unfortunately WiFi and Bluetooth only give the strength of the signal and not the direction, right?)
I saw the Gita robot by Piaggio, and that is what I want to do, but I don't know how it can works, anybody has some ideas? Though I think that is complex to do it for hobby but I am curious to know how do you think it works..!

Edit: I know that it is a frequent question but I found only 2 years ago post or older..!

Correct. AND, there is only a poor correlation between RSSI and distance.

I do. I think you should post a link, NOT expect us to go hunting.

Sorry, this is a video of it..!

Edit: I found this site where it is described..!

Gita's primary navigation system is a pair of stereoscopic cameras mounted on the robot, with which it's constantly performing visual SLAM. It then compares its SLAM picture with the SLAM that the user is doing, thanks to a stereoscopic camera on the user's belt
That means heavy image analysing and computing is involved. That's computer stuff. Not Arduino stuff.

Color blob trackers used in robotic competitions can be used to make a follower robot.

The Pixy camera includes an ARM processor that does the image processing. I do not know how well it works outdoors in bright sunlight. Note the Pixy 2 is out and is cheaper than the original Pixy. OpenMV is a device similar to the Pixy. There are lots of other examples but the following is cute.

Hi, thanks for the answer! Other people suggest to me Pixie, however what I think is: will it work for follow people? I didn't find any example online..!! What do you think?

Did you look at the video? Paint yourself blue and walk around naked. The pixy will then follow you, while laughing hysterically.

I like the blue paint on a naked body better, especially for following a pretty girl.

And maybe go around like superman and fly with a drone? Ahahahahahah

Anyway, I understood that it is not a simple thing to do for hobby, maybe in the future it can be done with a team..! Thanks anyway for the answers!
