Hi,
We are doing a little autonomous vehicle that will be controlled using an Arduino Uno. We need to drop ping-pong balls in a hole that is on top of a 50 cm height box. We have an extendable mechanism which is essentially a drawer slide. We need little motors to extend the slide. These motor needs to be as small as possible and we need to be able to measure the number of rotations that the motor is doing. Do you have any recommendations or advices for the motor?
thank you!
P.S.: The slide is about 400 g but we just need to lift the internal section not the whole slide
Hello @Frederic44!
Here is an excellent guide that will give you an idea of which motor would be best for your project:
For the application you mentioned, I’d say that a linear actuator would be best, however, since you already have a drawer slide you could use a DC motor with an encoder, or even a servo motor. If you need a lot of force you should use a geared motor, but this does not seem to be the case, and if you need a lot of precision the best is a stepper, but again this does not seem to be the case. For this reason the best would be a DC motor with encoder or a continuous servo motor, but to choose it you will have to see that it is compatible with your slider so perhaps it would be better to ask the manufacturer of your drawer slider which motor he suggests using.
