Tips for buying used robots
« on: August 19, 2010, 03:57:18 AM »
Hello friends:

Many people are off late buying used robots and i thought it will be useful for used robot buyers as a reference.
I have numbered them for convenience so i request anyone who adds a tip to continue the numbering...
A few tips to consider while buying a used robot:

1) Always buy robots only from reliable sources (known companies or companies that have a reputation to protect)
2) Inspect the robot for missing hardware, software, batteries, physical damages, motor or reducer damages, big backlash etc.
4) Inspect the Teach pendant and the related cables
5) Check for the required IO board (or atleast a one that you could use)
6) Try to avoid autions with "as is  where is condition" terms
7) Do not buy too old robots - you will end up paying more for spares than the robot itself
8) Always insist on the manuals - robot manuals + the peripherals if accompanying
9) Ensure that the key spares for the robot are available in the market prior to buying the robot - Identify the spares suppliers too..
10) Be aware of the licensing policies from the used robot manufacturers. Make sure of the robot manufacturers' charges.

11) If you are not a robot expert, hire a qualified company / personnel. A few more dollars will ensure a good buy
12) if necessary get the robot refurbished / overhauled. A good start = lesser trouble during operation.
13) Greasing is recommended
14) Buy a couple of small spares alongwith the robot - fuses etc
15) If possible include the robot training in the deal - however it is recommended to avail this service from experts
16) Remember the packing and handling charges are additional.
17) Do not forget the applicable duties and taxes in addition to the transportation expenses
18) Avoid online buying - usually you discover a lot more that what is mentioned on the specifications
19) Some bigger companies offer warranty - check all the terms and conditions. read the fineprint meticulously
20) validate if the robot purchase meets the reach, payload and the accuracy requirements of your application

21) if you get to carry out a health check by powering up, check for abnormal noise in each axes
22) You should also check the motors for overheating and over torqing in extreme stretched conditions
23) find out if you need a certain grade of IP protection on these robots depending on your application

25) Check the controller cabinet matches the Manipulator- many are mismatched
26) Always have the original Operating software and Key i.d. disc or robot number- very expensive to get a replacement

Depending on your son's age and your location I recommend that you check your local community college/technical school for a robot class.  Many offer night classes which make scheduling much easier.  Also keep in mind on-line course work is not for everyone nor are all on-line classes the same in content, presentation, instructor skill, etc.

There may also be a robot club at a local school where he can learn from other enthusiasts.

27. Check with the Manufacturer to see when they stop servicing the legacy robots.

28.  Check that the index (0) marks are legible on each axis.  Some day you will have to zero your machine and it would help to have these marks to know if you are in the right ball park.
Thank you!

24) dont forget, that if you want to use that robot in Europe you need the CE certificate

Check it twice, to be sure that CE is up to date, because there where changes in EU law in last few years.
When you will have to give final customer/end user  CE for robotic cell, you can have problem if one of components is not fulfill law demands.
There are no impossibles, there are only possibles waiting to be found.

Thanks for all tips, I add:
29) Buying a robot system without warranty: Make sure there is a warranty offered with the used system. A used robot supplier should offer a warranty with certified parts and labor. Technical support should be offered with the warranty.
30)Buying a used robot from an online venue: You will find many great bargains online, but beware of the lack of warranty, service, and support you are getting with the robot. Plus, there is no guarantee that the robot will work when you get it.

First of all make sure there is a warranty offered by the used system. Always buying robot from an experienced dealer. Try to buying robot from an auction because this may become visible to be a great bargain, but be alert of the lack of warranty, no guarantee that it will even power up and the lack of past history in my terms these are the valuable tips you cease use while purchasing used robots.
