100rpm or 50 rpm???

[harisankarsa]

I am planning to buy 12v dc motors for making a line follwer....shd i choose 50rpm or 100rpm???
which will be better to work with atmega8 and a light body construction....

12 V,  either thats a large line follower, or those are tiny batteries.

u can go for any rpm just as long as u can control it

[airman00]

as long as u can control it

Ill go a little more in depth- as long as you can control the motors with PWM  giving them speed control

[superchiku]

ya thats obvious without pwm forget motor control

[lkik]

wont you have to worry about wheel size too
