That just looks as wrong as looking down a gun barrel from the muzzle. I keep thinking,
oops, where did that glitch come from?

Agreed! shudder Those robotic arms are capable of acceleration
rates of zero-to-dead-flopping-meat in under a second. You wouldn't
catch me riding one.

My "real Job" was programming and maintaining a cell of four GMF robots for
three years. Once I got sloppy and held the hand pendant Estop override
while reaching in the cell. My arm went over the photo eye which told the
robot to come get parts. I got caught like a mouse in a trap. We wrote it up
as a robot malfunction cause I would have been in serious trouble for
intentionally overriding a safety.

I'm currently downstate. Attending a Fanuc M-710iC mechanical repair
class in the morning.

You are lucky. What robots, app, control?

its been 17 years now. I forget the model numbers. They were all six axis
G.M. Fanuc with G.M.'s version of a Fanuc control. The programming language
was very much like Pascal. Big exception, GOTO meant move to a certain
coordinate. I remember the computer was more wimpy than the super fast PC-AT
I had just got.

We were assembling VHS tapes and went from humans to robots. over 50 robots
in the whole line. My little piece of the puzzle was taking the output from
25 molding machines and placing the parts in trays to cool before running
down the final assembly operation. The whole line was scrapped out with the
coming of DVD.

Karel? A couple years ago I got roped into resurrecting a GMF welding
robot that had been sitting idle for several years that spoke Karel.

Sounds like the control I was working on. The programming wasn't bad,
as long as you didn't fall asleep while debugging.

I had another customer who was making throw-away VHS tapes, for
promotional videos and the like. It was a pretty clever design -- the
whole cassette had only 6 components: the shell, two hubs, the leader,
and two springs. The shell had several fold-ins with live hinges for
the hub brakes, the door, etc. Everything except the springs was
polypropylene, so if the assembly automation went down, the molded
parts were diverted and reground and went back into the molding
machines.

They overestimated how long VHS would be around, spent a huge amount
on hard automation, and offered to give it to me about two years later
when their market disappeared. That must have been around 1998.

Think of the consequences to the guy running those arms in the Mall,

being shoveled up off the wall and floors.

What's the acceleration rate for those? Equivalent G force to a human
rider for max accel to quick stop? Gory minds want to know.

Happy Halloween!

The max accel at the end of arm tooling depends on a huge number of factors.
I can say unf%^&ing believable. Two the four robots were a bottle neck for
the entire assembly line. At first they were 25% slower than any other
section. played a lot with end-of-arm weight reduction and tuning
acceleration of all the axis. Also the Jerk rate (rate of change of
acceleration) If the robot took off too fast the inertia of the parts would
pull them right off the suction cups. I got the plant manager's award (big
deal at the time) for removing my cells as the bottle neck. Only took two
years. They had "reassigned" the engineer before me when progress wasn't
good enough. it was the only project I ever worked on where part price and
technician availability was not allowed to be an issue.

What'd you do, up the suction to 423 inches of mercury, suck holes in
the parts, drop it to 350, etc? g Yeah, there's a lot to the
"simple" quick movement of parts from one place to another.


Only took two years.

Slow programming language, eh?

I suspect any robot manufacturer that knew their robot was being used
that way would cut them off from parts and service.

Yeah, one headline like
"ACME ROBOT VICIOUSLY SLAMS/RIPS 2 PEOPLE INTO BLOODY PIECES"
could put a real dent in their sales that year, ya reckon?

I'll bet the lawyers for the firms already have language in their
contracts against that eventuality, JIC, but it's still a bag of
worms.
