Hello
I am french forgive me my spelling mistakes
First of all I am currently in the terminal S SI and we must therefore realize a project. Me and 2 other comrades decided to make a robot that follows a person when it is done it’s race to help him carry for example a pack of water …
To follow this person we opt for an infrared emitter that the robot will follow thanks to these sensors.
But problem … we do not really know how it works …
I therefore allowed myself to contact you
To explain if you agree how to do it
Thank you very much, we hope a lot of you
Thank you.
We get asked that question a lot, and there’s no easy answer. Take a look at the practical example at the bottom of this article: robotshop.com/blog/en/how-to … ors-2-3683
Feel free to read through the entire article as well.
And I would like to know if you could tell me how it locates the person to follow (thanks to the remote control but more precisely with which transmitter? Infrared? Radio ?? …
It follows the remote control which you must have mounted on the rear of your belt.
There are sensors mounted in two locations on the robot and it will turn towards the stronger signal.
This can be done using IR or a sound, and the greater the number of sensors, the greater the precision.
Since we carry the products you linked to, we have updated the links in your last message.
The Pololu IR beacon are intended for that purpose specifically. Given that they need visibility on all sides though, you’d need to mount it somewhere visible from all angles.
The distance sensor would be useful to avoid obstacles, but the two are not meant to work together.
IR is best, except outdoors (where the sun can interfere). There are not many applications like this, so you’ll need to experiment.
