I'm new to hobby electronics and Arduino - so be gentle with me :)
I set myself a target of building a wall avoiding robot, so thought I'd buy a car chassis kit to start me off, this one in fact: https://www.sparkfun.com/products/10825
The motors (48:1) seem woefully underpowered, and the bot struggles to move around my lounge carpet.
Now I was thinking of getting these motors as replacements: http://www.hobbytronics.co.uk/motor-control/motors-general/mm-gear-motor-100
Now, my questions are: 1) Are my choice of new motors a good one? 2) What exactly does the ratio mean with regards to these type of small DC motors?
I'd like the bot to nip around my floors quite quickly, not moving like a slug and failing to turn!
All answers gratefully appreciated!
