Title: Motor Identification
Post by: extreme.aly on August 01, 2014, 11:32:18 AM

Hello people, I'm interested in making a Ball Bot, I have been doing research on it since a few weeks.
I'm good with everything, except the motor selection.
Can anybody tell me which motors are used on these robots in link below (or any similar motor that I can use), the specs (torque, rpm, voltage, amp)? or any suggestions over Brushless and Stepper Motor, which one is better to use for a ball bot?

I want my robot to carry almost same amount of weight (or less).

[EDIT]
Oh btw, I think I'm going to use these wheels:

 :) Hello!
Parallax has done some work with this type of robot. It might be a good thing
to look them up. Good luck!   :)
