I want to know if I can control the phidgets 42BYG40(M)-160-4A Nema 17 Bipolor 99:55:1 bi polar stepper motor with the Pololu 8-35v 2A single bipolar stepper motor driver A4988. I want to use two of each for the drive system on my robot I am making for completion. I am using the propeller board of education microcontroller.
I am in school doing this stuff for the first time and I thought that a stepper sounded like it would work well. are you saying this stepper will be to slow for my robot. It has to perform a couple tasks a line follow, pull, incline, and wall climb
Stepper motors are sometimes used as drive systems, especially where accuracy of motion of a flat surface is concerned, but stepper motors are harder to control and don’t provide much torque. the vast majority of smaller mobile robots use DC geared motors - they are inexpensive, easy to control and come in a wide variety of torque / rpm / dimensions.
It looks like the 42BYG series consume about 2.4A or more, whereas the Pololu controller can only provide up to 2A. You’d need a more powerful controller such as RB-Spa-696.
Also, why are you using stepper motors for your drive system as opposed to DC gear motors with encoders?
