Thread: More Mule then Rover?

    Re: More Mule then Rover?

    yet the snow bucket is still not installed
    Well, who's fault is that?

    It seems I'm the reason for the slow down
    Oh, right then.

    What fun would it be without overthinking? :-)

    Else you would just weld a 3/8" steel plate on front at a diagonal, that would plow just fine as long as you keep up when it's coming down. No fun in that. (Other than saving the work of doing the plowing manually.)

    jwatte, I'm still scratching my head about what type drive to use to lift the bucket.
    I have a ballscrew from a bridgeport mill, but with a pitch of .200" and a motor with 180rpm
    it would take some time to lift the bucket(@20sec. with 4 to 1 gearing of the gearbox).

    if I went to a chain drive, I could get it down to 5sec.

    Also, could you bolt lifting arms to the side, to give you a longer lever? Put the pivot point at the back of the bot, lift somewhere in the middle, and put the bucket in front, for additional speed gain (and, of course, torque loss, so that counteracts your 4:1 gearbox ...)
    Really, just add a harder/better/faster/stronger motor and call it good, I guess? :-D

    I think this is why professional gear uses hydraulics... Build high pressure in a storage tank, use it when needed to actuate with high forces quickly, as long as you're OK with some mush in the system and some lag in the control loop.

    Also, how far do you really need to lift the bucket? You don't really need to lift it much more than the regular ground clearance of the 'bot, right?

    how far do you really need to lift the bucket?
    jwatte, with the way the bucket was made I have to lift it 18" just to dump it.
    I'm thinking of lifting a total of 34".

    I think this is why professional gear uses hydraulics.
    jwatte, this is where the overthinking come in...
    hydraulics would be a easy to implement setup, I can get stuff at farm&fleet to do the job.
    but, I need to start playing at 5 am so I can still get some work done that day, and with 30
    neighbors that would be in range of the sounds the hydraulic pump, they may not let me play
    in their space at that time. (that would suck!)

    I have the same issue with electric winches.(too loud)

    My neighbors don't worry about their lawn crews using weed trimmers at 6am, soo ....
    Buy a shotgun, ignore the neighbors? :-D
