Hey.I'm a boy there are 15

Hey.

I'm a boy there are 15 years old and just chose the science way of my life. My hobby is to program robots and I think it's interesting. It could be nice with a robot who has an iron detector. So if you for example lost your keys then the robot could find it. It should probably be a small robot. There are probably a lot of iron around the robot but then it's good with the camera and light if it's dark. Then there could be a little map where you can see how far the iron thing are from the robot.

Hope it's a good idea because I really wanna get a code were I can save money. I already used a lot of money on robots and just wanna save a bit.

Thank you
