Robotics help: stronger motors?
I Am Blashyrkh asked:
I am a kinetic sculptor and I want to create a light following robot that walks. The mechanics for the walking are not new to me but the robotics/programming stuff definitely is. Ive been trying to figure out how to build everything and everything i find is for tiny little micro bug type things. The form I want to build would be bigger and would need stronger motors and obviously a bigger power source. (im even thinking of scaling up once i figure this first one out) Its basically two sets of legs, each with their own motor to facilitate turning. Since everything i find is tiny wimpy things my question is, if I build the circuit board and program it and everything the way I see it on other bots, what would I need to change to accommodate the stronger servos that I would be using? Its probably a stupid question but i am definitely new to robotics. I know I cant just put a bigger battery and stronger motors on the same board. What would I need to change? Also, if you don't mind, can I contact any of you directly for further questions? If not just say so.

The good news is that if you scale a robot design up the programming remains more or less the same, and yes, you can put bigger batteries and bigger motors (with more powerful driver circuitry) on your circuit board. The bad news is that if you simply double the linear dimensions of the design, its volume, and therefore its weight, goes up by a factor of eight. The good news again is that by redesigning the new larger size you can get the weight down again. If you are not into engineering calculations then you will have to find out empirically by browsing robot websites to find out what sort of motors people use to drive what lengths of levers are involved in the legs of your scaled up version.
