The problem seems to lie in that the press has a control panel and controller, and the robot has its own controller and control panel. Both AB, but I suspect that the robot does not have to ask permission before entering the press's work space. So, if it gets out of sequence it can dive right in if it decides to. Then the press e-stops until you remove the bot.
The problem for us (me and the night operator) is that it requires a password and more pendant knowledge than we have at the moment in order to back the robot out. So, we ended 2 nights with the robot inside the press. Imagine that kind'a scenario in a healthcare situation...
Yes, this does sound like a big one, Ralphy Boy. It would be a good story to tell at Design News -- to illustrate what can go wrong, how it can be fixed, and how safety worked when things went haywire.
Thanks for the thought Rob, but we are just now getting to run this piece at night. The 2 day shift operators are engineers and they are inside the debug loop. I may not even be told when it is fixed. It may just stop happening one day night.
The day guys have seen this a few times too though so 'we' didn't discover anything new. New machines are frequently slowly developing list of action items... This is a big one in my mind.
Those are great examples of what is out there Rob...
It looks like the current batch of sophisticated robots are mostly specialized in very narrow tasks. The hospital helpers come to mind... One washes hair, another admins drugs, another lifts in and out of bed. In a few years that will likely change. But how many jobs will be lost to a small fleet of HC Robots once they can do it all? Stay tuned I guess.
On another note... It's not that simple a thing to program bots for the unexpected. We have a new 400 ton press that is off loaded by an industrial Fanuc 6 axis LR Mate 200ic.
After certain types of faults or maintenance events it will some times attempt to commit suicide if the exact sequence of buttons is not pressed during restart. What it does is rapid into the press when the press is not expecting it. The light curtain is all that saves the robot from being terminated...
It has done this 2 nights in a row now. It's being looked into by the machine builder's code guys.
I am resisting hanging a 'Terminator' name tag on the control panel cause... no one will be laughing if it finds a coded loophole around the light curtain.
Back to the HC Bots... Take care when restarting after a fault... I wouldn't want my Depends (or anything else for that matter) on/in the wrong end.
Droid, it's true that the things we ask health care workers to do are considered disgusting. But, the robots can help keep nurses and staff safe and healthy. Lifting hundreds of pounds of dead weight to check for bedsores, change a bad pan or transfer a patient from a bed to a wheelchair causes thousands of back injuries every year.
Robots working with people could be a good solution for end of life care.
Last year at Hannover Fair, lots of people were talking about Industry 4.0. This is a concept that seems to have a different name in every region. I’ve been referring to it as the Industrial Internet of Things (IIoT), not to be confused with the plain old Internet of Things (IoT). Others refer to it as the Connected Industry, the smart factory concept, M2M, data extraction, and so on.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
