How do you know if your motors will be strong enough?
December 2, 2009
I'm new to the LMR community and want to build my first robot. I'm a linux enthousiast so for brains I have an beagleboard. This has an 500MHz arm processor and runs on 5Volt at 2 watt on full load. http://beagleboard.org/
It also has 3 serial interfaces so I would choose a serial motor controller.
But the problem is with the motors. I have my eye on the polulu 100:1 micro metal motor with 120 RPM and 0,7 kg/cm (or 10 oz/inch). http://www.pololu.com/catalog/product/992 and the 42*19 mm wheels and extended brackets.
I read that beginners should choose motors that do not go to fast, so I think this is a nice setup to start with. My only concern is how big can the robot be? Or better how much can the robot weigh? I mean, if I build this and see that the motors are underpowered, its a waste of good motors.
Or maybe have an example robot with this setup of motors? Or I can look at the size?
