I heard that this fall there will be some changes to a euro standard for safety and some companies are exploring wireless technology for teach pendants......
Any one have any info on wireless teach pendants......
basically who, how, when????
I know comau has a wireless teach pendant for a while now. Don't know about you guys but i am always loosing the remote control of the tv, how do you explain your customer that you don't know where you left the teach pendant.
But the advantage is you will not be limited to the wire anymore. So it does have a few positive and negative side of it.
Here is a link
And tech specs
Saw one back in 06. Motoman NX controller with a HP-3 arm. Was not made directly by Motoman, an engineer at Honda Canada did it as a project. Had a box to carry around and could not control more than one arm or external axis.
I'm waiting for ISO 10.218 for the controller to be released, may allow for a wireless pendant. That would be sweet.
I thought that as a safety requirement it was important to have a EMG on the TP.
and the EMG is usually hardwired.
How would they ever have a EMG signal in the remote mode?
do they have EMG for the satellites from the earth? a similar technology may be applicable?
I heard a technical presentation recently that included news on wireless pendants. In summary from what I remember being said:
1. Technical committees recognize the need and are trying to figure out methods & technology specs in order to give engineers a method of designing the equipment to meet the safety requirements.
2. Working through operational issues & requirements such as
(a) one pendant being able to control multiple robots...pendant is required to "login" to a selected robot and only control that robot while selected
(b) pendant must be "docked" when not in use
(c) if a pendant is used in a multi-robot environment but only "logged-in" to one robot at a time, then how does the ESTOP work to maintain safety?
...and so on. Many issues to be resolved, and the wheels of the ANSI + ISO technical committees grind away slowly at it.
I started this thread to see what issues any could think of and have come up with some myself.
Keep the comments coming.............
I always thought it would be a cool gadget....additionally the ability to convert existing pendants into wireless with a battery pack and wireless tx/rx box...
Negatives - weight, battery life, dead batteries, charging jacks, misplaced pendants
Might have to use a neck strap much like used w/ RC airplanes....I think a battery pack will add a lot of weight to hold for long periods of time...
Positives - obvious
I hope the new safety regulations allow for a wireless setup...pendant cables suck...
Seems like no one replied for a long time so maybe something has changed since.
Has anyone heard about wireless pendants? Mine drives me crazy. I keep stepping on the wire and it's so annoying especially while programming
The KUKA KRC4 teach pendant runs completely off of a network connection, including the E-stop, so at least in theory there's probably nothing stopping it from running on a wireless network connection, as long as that network is reliable enough that the safety packets don't experience any delay or losses -- safety-qualified networks are hyper-sensitive, for obvious reasons.
So we can not expect one commig out any soon. That sucks
as SkyeFire already stated, connection to SmartPad is ethernet. the actual media (copper, fibre, wifi) is not important. i think Siemens has wireless multi panel for a while, then there are italians with slick compact pendant etc:
OTC has it with new series...
ABB recently ran a demo of a windows tablet running a teach pendant interface wirelessly. Didn't see it myself, so I'm not sure if it was full-featured or a limited function.
I know the limiting factor at the moment is that safety regulations require a direct hardline for the E-stop, in case of emergency. Until a reliable wireless e-stop is developed and approved by safety regulators, this idea won't get very far.
Actually, unless I recall incorrectly, the RIA standard for wireless safety-rated devices (like E-Stops) have already been set. And since safety-rated devices can be connected via TCP/IP networks, now, the network media (wired or wireless) are essentially irrelevant. If a network connection is lost, or suffers too many packet delays, the system fails safe. A sufficiently robust and high-speed WiFi network could probably become part of a safety-rated network without the safety devices even noticing that they weren't connected via Ethernet "hard lines" anymore.
On the other side of the coin, a lot of end users probably don't have any wireless systems in their approved safety device catalogs, simply b/c such things haven't really existed until recently.
