# Comparing industrial robot arms [closed]

I'd like to study the capabilities of industrial robot arms. For example, to answer the question how does price vary with precision, speed, reach and strength?

Is there a database of industrial robot arms including information like the price, precision, speed, reach and strength of each model?

• I'm voting to close this because I don't feel that there's any "right" answer - everything could probably be found out with an online search. That is, I feel that the answers are all going to be "primarily opinion-based". Jul 23, 2015 at 12:37
• @Chuck: The right answer than I am looking for is a link to a database that provides this information.

For example, how does price vary with precision, speed, reach and strength?

The price vary a lot, from a couple of hundreds of bucks to hundreds of thousands of dollars ( Willow Garage's the one-armrobot PR2 costs \$285,000 and The two-armed costs \$400,000 ), it goes up- as you can guess- whenever the robot arm is precise, fast, long, strong, collaborative (i.e. designed to interact with its environment), or have more DoF's (Degrees of Freedom). Also, take into account the flanges, tools, the palette of software they come with, certifications, etc. It really depends.

Is there a database of industrial robot arms including information like the price, precision, speed, reach and strength of each model?

I don't know of such a database, but you can find all these information (except prices, these companies are pretty secretive, they usually reveal it to potential customers. I work on KUKA's robots in my company, I didn't know about their price until our PR told me about the deal) on the Robot's manuals available on the companies' websites. If you want to narrow down your choices, check what's available on the applications you want your robot to perform (if the robot will do repetitive work inside a confined space, there's no need to buy an expensive collaborative robot). I think, the big guys in the industry like Kuka, ABB, or Fanuc have a complete range of robots for different applications and at different sizes. Check this link out:

• "except prices". Yeah, the price is the thing I'm really struggling with. It seems the only robot vendors who advertise prices are those competing on price such as the Baxter robot from Rethink Robotics. Interesting you say that collaborative robots are expensive when Baxter and the Universal Robotics UR series are relatively cheap. Do you mean collaborative robots from the likes of KUKA, FANUC and ABB?

• Most of the sophisticated robot arms are not destined for personal use that's why they seem very expensive, but rather to industrial one. They perform routine, repetitive and tedious works 24h/7 in production lines, so they replace many humans while eliminating human errors, which is cost saving if you are a Car Manufacturer like WV or Mercedes.

• What I mean by " collaborative robots" are the ones that interact with humans without hurting them. The one I know about is KUKA's LBR iiwa kuka-robotics.com/germany/en/products/industrial_robots/… that has torque sensors on each axis, so it can detect any collision or contact with humans.

• Yeah, the KUKA LBR iiwa is $200k. – J D Jul 26, 2015 at 22:41 • I don't think it's$200k, in Europe it's around €55k Jul 28, 2015 at 8:43
