    seems like you're missing an axis of articulation in the wrist...shouldn't be lifting the object towards you...should be able to lift parallel to the plain from which it was lifted from....surely?
    Either that or the wrist articulation is in the incorrect plain

    Build Question:
    How do you plan to counter balance the machine? You can lift 7,000lbs (roughly) but the vehicle will be very front heavy and likely to fall face first.
    Are you adding a weighted backpack to the robot? It’s common in heavy equipment but this will affect the robots ability to walk.

    It would have been so much easier to put it together if they only had a power loader... you know, like the one from Aliens!

  • Brandon B

    So FYI, in your calc, it should be pi*D^2/4. You show 2, but the conclusion is still correct. :-)

  • Paul Byrne
    Paul Byrne 13 days ago

    Your math is wrong. The area of a circle is Pi.R^2 as the radius (R) is D/2 then R^2 is (D/2)^2=D^2/4. You had D^2/2 which means that your force is only 50% of what you calculated...BIG error guys.

    Will you be using limit switches to protect the pump(s), cylinders, and joints?

    • the Hacksmith
      the Hacksmith  21 day ago +1

      It would be a poor design if it could break itself like that! All cylinders can extend and retract fully :) no limit switches required!
      But we will have full positional feedback for other things 😁

  • Bradley Weingartner
    Bradley Weingartner 28 days ago

    Okay, from here that looks more like 3/8" plate. That's insane. Going to need an super heavy base for this thing not to fall over when it's all put together! Haven't done the math, but my intuition tells me 1/8"-3/16" plate boxed like that and reinforced in a few key areas would be more than adequate for those forces.

    There is a slight mishap in thr calculation for the 3" circle. A= pi *(d^2 / 4) would be correct. Because you have to sqare the 2 in the division too.🤗

    While i only just saw this video, and I'm ok only a carpenter, i do believe there is an error in your lifting figures. Why? Because a lot of the pressure of a lift is going to be in the jaws, that is the weak point

    Not even sure how people are impressed with this. Completely slow and unusable. That will the most boring completed project. Robot that will take an 15 mins to do a simple task.

      @the Hacksmith Fair enough. I'll watch the rest and also subscribed. I look forward to the end product.

    • the Hacksmith
      the Hacksmith  Month ago

      Helps if you watch all the videos. That is a test hydraulic pump. Not the final one because we are at the beginning of this build. It can be 10-20x faster with a proper pump

  • Rechtschreib- Fee
    Rechtschreib- Fee Month ago

    9:37 you need to divide by 4! A = pi(r^2) = pi(d/2)^2 = pi(d^2)/4 So you end up with half the power instead.
