Bob Moves!

It’s ALIIIIIVE!

While I did an initial experiment to prove to myself I COULD move Bob, the exact who’s and how’s, and whatsit’s have been a little trying, requiring a minor re-design and some creative implimentations of the bungies.

Following a request to get some more details on all this mechanism, I’ve got a bunch of photos.

First, the axis.

A PVC pipe inside 2 pieces of larger PVC pipe, bolted to the table. A hole drilled allows the EMT pipe up and through, to act as both Bob’s spine, and the activating lever. A couple of cauder pins help hold the EMT from sliding.

The EMT has a nice little “S” bend in it so that when Bob is flat, so is the under-side.

Photo of the gate latch, a re-designed bend in the pulling lever to account for needed lengths of the bugnies, and the temporary switch of a clothes hanger. I need some pulleys to install the final switch. I know the new bend is not pretty, but it’s what happens when I did not foresee it’s need…

And the guts of the mechanism.

The “top” bungie slides along the EMT to that new bend, preventing Bob from doing a face plant. The other is the driving bungie. Both hook to the legs of the table.

Finally, the long awaited video of Bob in action. (Bob is not fully corpsed yet, need more latex, waiting for payday. He’ll also scream…but that’s a ways off yet.)
