I am currently planning on developing a new 'bot. I want to make it along the lines of a micromouse style robot, using stepper motors as my drivetrain. I want to make it basic for starters (basic object avoidance). Then down the road I want to add to it to make it more advanced.
So, for starters I am toying with the idea of directly connecting a wheel the the shaft of the stepper or to use the gear that is on the motor to turn a geared wheel of some sort. What should I do?
Also I am trying to choose a driving method for the motor (it's unipolar btw), driver chip (good recommendation would be greatly appreciated), or premade board, or make a driver out of discrete components. Which route should I go?
Any input/ideas/recommendations would be nice.
Here is the motor I'm planning on using.http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=171601
