i have this idea for a butler bot. inspired by Norrislabs (BDS) beverage delivery system http://norrislabs.com/. it will have 1 propeller board it will handle motion, the sensors and a slave for bat lvl temp snsor and controlling the peltier units. it wil have 2 window up/down motors with a h-bridge for each. it will be powered by 2 12v bats for the motion and a 7.2 bat for the prop boards and speakers. the whole thing should be about 4 ft tall.the fridge should hold 3 sodas depending on the size. the fridge wil be cooled by 2 peltier units one on top on on bottom.
update:ordered the prop proto board,ir sensors
got the proto board..progres on butler bot will be slow learning a new language is fun
decided on the shell...2 clothes hampers
getting ready to post it as a work in progres
