Raspberry Pi Motors

[GameModeLiam]

I have put together a list of parts I will get to build my first Raspberry Pi robot toy car that will be fully autonomous,  however the only part I am missing are the motors. I have searched around and can't find what motors other people are using or what motor I should even be looking for. If anyone can guide me towards what I should be looking for, it would help a lot.

 

I will most likely use four motors unless there is any better form. I don't know if a higher rpm is better, or if I need a gearbox type thing that will cut it down. Also if anyone has any prior experience or could explain what the ideal motor would be for a small car like the one I am building, that would be great.

You're probably looking for something like this:

 

You can usually find these at a hobbyist shop or an electronics shop.

or rip one out of an old controller or cd player

Rc cars are a good source

True, depends how many he needs and if he has one of those to spare

please be sure to doublecheck the amperage of the motor and the raspi. if its to high, you might want other electronic components as well

You need geared motors if you want it to move. Something like this:

Look at the speed to torque specs and decide what you need for your application.

 

Are you using a motor controller shield? You should use one because the Pi cannot provide enough amps to run motors under load.

Thank you this is exactly what I needed. I am using an external power supply (AA Batteries) and a l298n board in conjunction with the gpio pins on the pi. I am using this guy's series as a rough guide
