nasa crawler a great idea

e14 Contributor

I think Ben should build a remote controlled crawler using the basics of electronics and at low cost

if this it made it will help me very much and even possibly give others ideas.

please can this be done and please everyone support me in this.search?q=nasa+crawler+desighs&qpvt=nasa+crawler+desighs&FORM=IGRE#view=detail&id=6A59FD76FAC08F390778CFB01CEABB546E424E8F&selectedIndex=16

  • I would make a wireframe model.  We need to isolate the degrees-of-freedom.  The windshield wiper we see in front could possibly be crudely modelled upon a real number, say, between 0 and 1 for a single point in time.  Most stuff a machine can do can be modelled this way*.  A fn private to the renderer would intermediate its way to the display.  The rub is that we will need an elasticity model on anything mechanically reactive, like suspension components in the bogey wheels, or stretchiness in the tracks.

     

    I guess what I am trying to say is that, for such an ambitious project, I would try to run the software and hardware development in parallel.  Skining the wireframe can probably come last.

     

    ==========

     

    Counterexample:  Bar feeder on a horizontal lathe.  Some linear DoFs have to be modeled to infinity.

     

    [They use two els in 'modeled' across the pond.  We like to keep it brief here in the States.]

     

    If it has a steering wheel, it may be more convenient to encode its position as -1 - 1.
