I’m always on the hunt for the next big robotics story and today is no different. So, to say that I was thrilled when I happened upon a rather interesting online discussion would be an understatement! Fuelled by some of the robotics industry’s international heavy hitters, the conversation of second hand robots versus new robots was up for debate. Spurred on by this extremely valid issue, I ask the question…is newer always better? My first response? Yes! I mean let’s consider a few key points; a new robot is faster with productivity enhancements and ancillary options, like vision, not found in older robots. They are flexible and accurate for the changing face of production and there’s very little downtime, as maintenance requirements are low and parts are easily located. All in all, it’s easy to see why I would endorse new robots. But, after some investigating, I looked beyond the shiny façade of a brand spanking new robot and wondered if perhaps there is still a place for the proven standing of a second hand robot. This is the part where every man and his proverbial dog weigh up the cost versus benefit argument. And they would be right. There is no denying that choosing to implement or to continue using a second hand robot does come with some considerations. Factors like the possibility of longer periods of downtime; as spare parts may be difficult to locate coupled with the chance that the technology has been outmoded resulting in less application flexibility and speed. But when it all boils down there is really only one question…does the second hand robot perform well? The Manager-Process Engineer at FANUC Robotics America Inc, Paul Santi puts forward his opinion saying, “By ‘performing well’, I take this to mean: safely meeting production rate and quality targets without excessive maintenance, supporting labour, or energy costs. If a robot is performing well and the user plans to continue using the robot indefinitely for its present task then there is probably no strong reason to change.” adding that, “FANUC Robotics has a feature that can monitor robot performance and detect when certain components should be replaced as part of a preventative maintenance schedule. This reduces downtime due to unplanned maintenance and increases the usable life of the robot.” Another consideration in choosing a second hand robot is cost, and I don’t necessarily mean the purchase price. I’m referring to the savings that could be made by not having to update existing programming or allow for integration and safety differences or even to re-train staff for that matter. Cost can also play a huge part for small companies. These businesses simply don’t have the budget to invest in the newest technology right away. Choosing to install a second hand robot gives them the chance to “test” the technology prior to making bigger capital financial commitments. Clearly in this industry there is always going to be something bigger and better than before. The question is though, what is going to suit your business? I guess when it comes to second hand robots, the old adage really be true…“If it ain’t broke, then why fix it” By Prue DeAraugo Robotize Features Writer
