Possible purchase of a used kuka robot
« on: March 17, 2017, 07:17:47 PM »
Hello,

We have the opportunity to buy a used Kuka 150 série2000, with the KRC2, for a ridiculous price.
It is from 2004.
Before going any further, we would like to know if it is a good idea to start experimenting with this one (we don't have any experience in robotic arms, but do have in more general cnc (3-5axis, water jet, laser, ...).
Is it just spending cash on a pile of steel, or is it usually sturdy enough to go for many more years?
We haven't checked it yet, but will eventually if we can get some positive feedback on this kind of arm.

Second question, how easy/difficult is it to integrate end-effectors?
For a starter, something like a spindle or a gripper?

Third, if we understand correctly, Kuka/prc can drive this old version of the arm. Is that correct?

Last, how do you interface this arm with a computer? (old KRC2) We have yet to dive properly in the manuals, but some initial light from experienced people always helps.

Thank you for the information

Nico

Hello Nico,

The robot sounds good, just take care that everything is included, such as the KCP control panel and the cables (which can get quite expensive if they are missing).
Most likely the robot comes with some pre-installed IOs, at least digital outputs, which you can then use to interface with your endeffectors, e.g. the valves that control your gripper.
The difficulty of the integration of course depends on the desired communication, so it's hard to give a definitive answer. For a spindle it might make sense to get an analogue output module to set the spindle speed in fine increments. With KRC2 robots you can still use the serial port, e.g. to easily communicate with an Arduino.

And KUKA|prc works just fine with KRC2, I think even the USB ports may work - but I would recommend using the Windows file shares over Ethernet, that's usually the most convenient way to send your *.src files.

All the best,
Johannes
