Hello guys. I'm building a robotic arm as a hobby of mine and so far I am just working on the basic movement operations.
My question is:
How do I increase the output torque from a low-torque stepper motor?
My own thoughts are that I should get/install/create some sort of planetary gear train for the stepper motor and make sure it's at a ratio that would at least give me 3-5 times the output torque.
But here's my problem, I'm not too good with gears. So I would have to ask one of you smart guys how many gears I would need, what ratio/size do they have to be and how do I go along and build it?
Again, if anyone knows a website that sells a planetary gear kit or something similar that would increase my stepper motor torque, then by all means just throw me a link. It would make my job much easier!!
Thanks.
