| Whoo, okay, interesting project and like you REQUESTED, no further comment on the practicality...
I'd use servos to drive the drills' own speed controllers via the trigger- take off the spring if you can to reduce servo load, and the 148's should be fine. I don't think you need to change the plugs unless you have the really old "G" plugs, then yes you can just put newer plugs on for the 6100e receiver.
I think a bigger issue will be the size of the battery needed to propel and steer that thing around the yard for a reasonable time at the speed you want. How long does it take to just mow the yard now walking behind the mower? I guess a big lipo or A123 pack would be feasible, but not cheap. Hmmm how can you measure the effort to propel the mower, at a projected (guesstimate) weight- push it through a scale with some ballast to represent the battery/propulsion system weight? Then convert to power and time to mow the yard, and see how much battery you need.
What about propelling it with a weed-wacker motor (gas) and steering via the front wheels?
Never, ever, ever, ever give up. |
