#CES2019: Robots will be everywhere.
December 10, 2018
Investments in robotic designs of all manner are through the roof. In the past 18 months alone we have seen at least a 10 fold in RFQ robot projects come our way. Assembly line robots, personal butler robots,Â collaborative robots, warehouse robots, if you can think of a use for a robot there is pretty good chance that someone, somewhere, is working on that robot design right now. Many of these new robotic designs will be introduced at #CES2019, there will be robots everywhere. So how does rapid manufacturing play a role in the exploding robotics industry?
All new product development needs some design flexibility and manufacturing options that match this need. When it comes to robots, design flexibility is even more essential becauseÂ you are designing something completing new that you think the market will accept and adopt, but you really donâ€™t know until you launch. Rapid manufacturing: low-volume rapid tooling and no tooling rapid manufacturing technologies offer flexibility. Industrial and manufacturing sectors have benefited tremendously from robotics and the ROI has basically been established through market history of successes and failures. But when it comes to the vast consumer market we are only just starting to get our feet wet on robotic designs that may one day be commonplace in our everyday home and office lives. So, if there is no great history of prolonged robot design success in everyday life what is a good manufacturing strategy for bring new robot designs to life?
My advice? Save your project dollars and stay away from costly mass production injection molding tooling as long as you can. Instead opt for no tooling manufacturing technologies like CNC machining or urethane casting (tooling yes, but disposable low life tooling) to help you test and validate your design in the market. You may be very confident in your design but erring on the side of caution until the market gives you some feedback as to whether you are on track or not is always a viable strategy.
CNC Machining Robots â€“ A great option for metal or plastic robot parts. Highly durable parts, an incredible range of surface finishing options, and precision dimensional tolerances are all good manufacturing benefits when making robot parts via CNC Machining. The process is one-off, so the next iteration is easily achievable with no project dollars wasted on tooling that would likely be deemed useless if you have to change your design based on market feedback.
Urethane Casting Robots â€“ if your final manufacturing process will be injection molded parts, then, in my opinion, there is no better option for early testing and design verification than urethane casting (vacuum casting). it very closely mimics the properties of injection molding, allows for detailed surface finishes that are available through the injection molding process and urethane casting can self-colour each part so no post finishing is necessary unless desired.
3D Printing Robots â€“ Not my favourite manufacturing process for early robot samples but I feel it needs talking about because 3D printing is everywhere these days. My reservations are in large part because when you bring 3D print design into the mix it often leads to designs that are not mass manufacturable. But, if you have a highly specialised robot design, that is a niche low-volume and high-profit margin design, then 3D printing may be for you. NotÂ my choice for robots, but it has its place and is getting better year over year.
Save your capital for a later date when you are truly ready for injection molding and mass production of your robot. Embrace low-volume rapid manufacturing technologies for the speed and design flexibility that they offer. It is easy to make the next iteration when you have not invested in tooling. It is incredibly painful and sometimes not economically possible to make that next iteration when you have invested heavily in tooling. Your robot might just say thank you in the end, if it has a speaker . See you at #CES2019, HLH Booth LVCC 62329.
