Under Floor Inspection Robot

Introduction: Under Floor Inspection Robot

About: Retired but working.

I wanted a method of inspecting the crawl space under a house. Very narrow and dark! So I started with a toy treaded tank with remote control and video camera! It has a nice treaded design to crawl over uneven surfaces. But I found it had only 1/2 inch ground clearance and it soon hung up on a stone.

What to do? *3D print bigger wheels!*

Step 1: Some Good Wheel Designs to Start With...

but I had to modify the wheel design for the axle with a screw attachment, to offset the body of the wheel from the vehicle, I needed a treaded design, and it had to be strong!

Step 2: What to Do for the Tread?

Treads of an exact size are hard to find. Brainstorm - use two sided velcro tape, looped around both wheels, and "taped" to itself. Then add small chunks of the tape as gear teeth on the inside, and tread pads on the outside!

And put gear teeth into the wheel design.

Step 3: Finished Wheels - Treaded - With 1.25 Inch Ground Clearance!

And a super cool spoke design!

Step 4: A Short Flash Video Showing the Finished Result!

    Hi Michael, mixed. By remote video I could not easily tell if the soil was level or slanted, so I tipped the vehicle over a few times. I started to add "flags" to the front, visible in the camera view, to show vehicle tilting. But have not gotten back to it!

    Brilliant! I wish I'd have thought of that Velcro idea when the drive belt on an old Reel to Reel machine I was transfering to PC went . Would have save me a whole lota headache.

    Great idea.

    Tank treads made of two-side velcro tape have advantages in: very strong, not stretchable, no tension pulley required, easily create any length, and replaceable in a few minutes!

    Disadvantage: doesn't look as cool as regular segmented treads.

    This looks beautiful!
    Are there more Instructables on the way to help us create the whole thing?

    Ha! That's an excellent solution for a lot of problems! I wish I'd thought of it.
