When you're outfitting an automated assembly cell on a secondhand budget, the first fork in the road is usually: do you buy several lower-cost arms to spread across workstations, or one higher-spec robot that does a specialized pick-and-place job? Here are two used industrial robotics options that sit on opposite sides of that decision. The first is a lot of L.J. Electronics ATLAS II robot arms with accessories. The second is a used IAI CORP IX-NNN6020-5L-T1 SCARA robot system.
Quick verdict
For a shopper who wants a single, purpose-built SCARA robot for automated pick-and-place, the IAI CORP system is the clearer fit. For a team that needs multiple arms for bench work, training, or spare stations and can accept an as-is, no-returns lot, the L.J. Electronics ATLAS II lot gives you more machines for less than the IAI's listed price. The IAI is listed at $10,000.00, the ATLAS II lot at $5,225.99, a $4,774.01 gap. The ATLAS II lot is the multi-unit option with more condition uncertainty.

Where each product wins
The L.J. Electronics ATLAS II lot wins when you want more physical units on the floor and are willing to work through surplus-condition quirks. The IAI CORP IX-NNN6020-5L-T1 wins when you want a more complete pick-and-place package with a defined SCARA spec.
Product notes
L.J. Electronics ATLAS II 2 (Lot of 5)
Start with the L.J. Electronics ATLAS II if your priority is getting multiple robotic arms into a lab or production-support role. It includes five arms plus accessories, which makes it practical for simultaneous workstations, student training, or a pool of spare units. All five are reported to power up, and the model number ATLAS II gives you a consistent platform across the lot. The catch is condition transparency: the seller acquired them in a surplus sale and doesn't know usage history, no further testing was done, one unit's front LED doesn't blink (unit number 4), and the photos show missing or broken parts. It's sold as-is with no return rights, so you need to be comfortable buying on visual inspection and power-up confirmation alone. If you have the time to refurbish and a tolerant setup, the five-arm lot is the higher-unit-count route.
IAI CORP IX-NNN6020-5L-T1
The IAI CORP IX-NNN6020-5L-T1 is the more specialized option. It's a used SCARA robot system designed for automated pick-and-place operations, and it comes paired with a Hover-Davis QF01-16 tape feeder. Precision placement, cleanroom compatibility, and controller integration are part of the package, so it's aimed at a production environment where repeatability and feeder-based component handling matter. The trade-off is the price: it's a single used system at a higher listed price, while the L.J. Electronics lot offers multiple arms for less. If you need one cleanroom-suited robot with tape feeding and table or inline mounting, this system packs the needed capabilities into a single purchase. The listed dimensions of 58x50x85 give you a fixed point for cell planning.
Final choice by use case
If your use case is a single pick-and-place station where a defined SCARA spec matters, the IAI CORP IX-NNN6020-5L-T1 is the more complete match. If your use case is multi-station assembly, training, or a parts pool, the L.J. Electronics ATLAS II lot gives you the most arms for the money. The deciding factor is whether you value a higher-spec single robot or a larger quantity of arms with as-is risk.
