| What would need to be done, add some randomizing factor on movements, or is drunkeness different than just that? |
|
Quoted:
you could add random values to positioning data - they would skew movements and it would probably appear to be drunk. change the magnitude of the values randomly as well for fun... we already do this in CNC programming line production robots to even wear on joints, if they do the exact same movement over and over it will wear parts faster. |

It would be more than just randomized movement. Actually, i think there were be very few randomized movements.
You would want to change slew rates and randomized endstops (either changing optical read distances or radian stops). That way you would get overshoots or undershoots at inconsistent movement rates. Then just some slight randomization at the end. That would be pretty close to drunk. |

Quoted:
The robots I work on sometimes act drunk. They get all freaky then crash into the hard stops. Usually an open in the encoder feedback loop. drunk assholes. Pretty much that. I've had them run away and smash up a lot of expensive stuff in the process. 
That's why the fenced work cells are the size they are. |

Losing the encoder feedback, or tach-monitor feed back should cause a fault and an immediate E-STOP. Who is mfg. of drive? (worked on this type of equipment forever.) Retired, enjoy the subject. |

"No it's a robot problem. It's always the robots fault!"..... I get so sick of hearing that shit. The sumbitch does what it is programmed to do every time all the time. If not then it don't do shit. Makes me want to stomp a sack of kittens when I hear that shit. |

Makes me want to stomp a sack of kittens when I hear that shit. LOL. Yep it's programed exactly right. Oh you mean you put the wrong gearing ratios in the program.......I had no end of hell trying to convince the engineer it was a software issue not the robot. Indramat/Rexroth and some Mitsubishi motor controllers. Using GEFanuc 90-30 PLC with Horner APM modules. The open in the encoder cable generally causing incorrect stepper position counts. |

Here ya go OP  Just create several programs with random and inefficient points and random ACC values and slew speeds. Then add in some Registers and IF = < > statements to call them at each move in to and from the work piece. Would look pretty odd to the staff that looks at the robots every day and says "Robots, how the fuck do they work"   |

Quoted: The one that smacked me in the head several years ago was not drunk. I however may have been a little hungover from the night before. Fanuc 420 at 100% speed will lay you out like a boss!ETA: must have hit me so hard I forgot the model # I had a dream the other night I was in the cage at work with three Fanuc R-2000iB that started up when I was in there next to all of them. I was scared! Ducking and running. Assholes tried to kill my me! |
