What to Know About Buying a Used Robot

Used industrial robots are a popular option for companies looking to automate without breaking the bank. Used robots can save buyers between 40% to 60% compared to the cost of a brand-new robot while still providing many of the same benefits. The used robot market is more accessible with the ability to buy through online marketplaces in addition to the growing number of robotic equipment suppliers. When buying used it is important to do your due diligence to ensure you are getting a quality industrial robot. The following are important items to be aware of during the used robot buying process.

• 1. Know who you are buying from - First off, finding a reliable used robot supplier will significantly lower any risk involved with purchasing second-hand. Reputable robotic equipment companies will thoroughly test used robots to ensure they are in working condition before listing them for sale. They will also be upfront with the robot condition and history. If possible, it is best to avoid robot auctions and instead buy from a used equipment company, such as Robots Done Right. RDR carries a wide variety of used robots for sale including the FANUC Arcmate 120ic and Yaskawa Motoman MA1440.


• 2. Know the condition of the robot - It is important to get as much information as possible about the condition of the used robot you are buying. Has it been reconditioned? If not does the seller offer reconditioning? Are there any missing or worn parts? Is the controller and teach pendant included? If buying online make sure the seller can provide pictures of the articulated robot. You want to have a good understanding of what you are buying so there are no unexpected surprises after the sale.


• 3. Find out the operation hours - Operation hours are the total hours a robot has operated during its lifetime. These can be a good indicator of the condition and shelf-life left on a robot. However, even if the FANUC R-2000ic has high operation hours it should not deter a sale. Well-maintained robots can operate for 100,000 hours or more.


• 4. Know the maintenance history - As mentioned above, a well-maintained robot can operate for a long time, lasting up to several decades. Robots need routine maintenance to ensure they continue functioning at optimal levels, prevent breakdowns, and ultimately extend their shelf-life. Buying a used robot with a good maintenance record ensures you are purchasing a quality industrial robot.


• 5. Check the controller matches and is the original - Sometimes with used robot sales, the controller and manipulator may not match so it is important to verify the controller model. It is also important to find out if the controller is the original one for the six axis robot. Operation hours are stored on the controller, so if the controller is not the original the operation hours may not be accurate.


• 6. Know where you can get spare parts - Used robots will typically need used parts for spares. Having spare parts is part of maintaining an industrial robot. Buying a used robot from a supplier that also stocks used parts will help you easily locate consumable parts to protect your investment.
