What distinguishes a robotic toy from a tool?

Being able to sit on it, perhaps?

  • I want one, but I doubt I could afford it as a toy!
  • Why not operate remotely which would make more sense you just need cameras and you would have it made

    Well, if you're trenching in Northern California soil (mostly hard clay), you want the weight of the rider to get the needed leverage!

    I watched this for a few minutes, and thought "wow he's really not getting very far on his trench". And then I realized the video was just looping. :)

    Seriously though, I think I could dig the trench faster by hand, but it wouldn't be as much fun.
  • I did a Google search:
    Komatsu PC01

    $79 at Kohls....
  • I'm 67. I've had to shovel snow from a driveway to the road...and then take aspirin. That's a tool.
  • I can't be the only one wondering how to operate those things.

  • Operating backhoes and front end loaders is an art. When you see efficient and smooth movements you are watching a master at work. I have often wondered if a miniature arm with encoders at each joint beside the seat would be a simpler way to control the motion of the exterior one.

    It would likely be easy for the first half hour of use. Once a person is used to operating the real controls, I'd think they'd be much faster with the inputs than trying to manipulate a miniature arm.

    I'd think once a person had enough practice, the motions would come without having to think about.

    The problem is the relative cost of hydraulic proportional valves vs hand operated. I have had moderate success with PWM-ing the coils of a basic directional valve (open-loop) but I need to give it a jolt of 100% current just to get the spool moving. From there, it's really nice. I can regulate the velocity from a creep to full-tilt. I intend to pursue this because at the very least, I can eliminate hydraulic flow controls on machines that I retrofit, without having to spend $1,500 to $2,000 per proportional valve.

    Yes, the price difference between a regular valve and a proportional one was a bit of a surprise when I started working on servo-hydraulic systems. The first valve I replaced was $4895.00. Amazing what they could do though.

    EDIT: reduced image size - that thing was huge!!
    So, I'm reading this thread and it occurs to me my shirt is appropriate to this discussion!

  • Where can one get a shirt like this?

    It was for sale on the website many years ago. @Ken Gracey might be able to tell you better. I haven't seen any shirts for sale in a while.

    Now, I consider that a toy for boys!
  • Ah but a very useful tool application for laying down electrical conduit I wish I had something like that about a month ago when I was doing this project
