Learn from my Robotics Fail
« on: January 15, 2011, 05:00:07 PM »
Funny thing happened to me this afternoon.

I was intending to glue the pico servos from NINA's eyelids to the stereoscopic head, and I discovered the bottle of liquid weld I had opened previously and was intending to use was shut tight by its own glue. I attempted to open the lid from the bottle with a pair of pliers, but the tube twisted in my hand and exploded, covering my hands in gooey liquid welding goodness that began to eat through the skin of my fingers and nails immediately. Good thing I was near a sink where I could rinse thoroughly. So aside from exfoliated hands, I'm okay.

So...yeah...don't do it. :P
I think the chauffeur did it.

.......

He did.

Similar thing happen to me a few days ago, except it was super glue...
Dries in 2 minutes :o
Fortunately it was only a couple of fingers  on one hand, and the Acetone was just a arms length away.
Not that it did my hands that much good (burnt them!) but it got the glew off :)
And Admin said "Let there be robots!"
And it was good.

 Never, never , never, glue a servo...they die and have to be replaced...put on the thinking cap and find a better way to mount hardware..how do I replace a part on your production model when all the glue runs out, or I don't know what kind, or I just don't have any.

Hmm...good point.
I guess I've just always been inclined to believe subconsciously that a servo or a motor lasts forever, even after I've had a servocity power servo die on me before. I'll definitely keep that in mind when mounting motors and servos. Incidentally, since power servos from servocity are so expensive and they can die too, maybe I should just get into building my own servos using a cheaper gear motor and a potentiometer.

I don't think I want to build my own, too time consuming but if I have to replace the gear set in my $75 servo's I want to get them out in one piece.

Hi,

I don't think I want to build my own, too time consuming
But very gratifying, as you can then control each parameter to suit your particular needs.
You may find The OpenServo Project worth a look-see.


but if I have to replace the gear set in my $75 servo's I want to get them out in one piece.
Oh, then just add lots of glue, then they'll surely be "in one piece"   ;)
