Ever yearned for a wireless communication system for your robotics? Fed up with cables and their associated breakages and disconnections? Want lower installation and maintenance costs? Well, wireless robotics is now a reality. In fact, it’s been here for some time, providing totally reliable, noise-resistant communication at a growing number of manufacturers that have adopted the completely unique Wireless Unit from SMC. To help anyone who is still hesitant about wireless communication technology, Juanjo Jubete, Wireless Unit Product Specialist, at SMC Spain, addresses a number of common concerns in this short Q&A.
Q1. How can potential users overcome their fear of the unknown in terms of wireless reliability?
A1. It’s a common misconception that wireless is not as reliable as wired, but how many wireless systems have we got functioning in our homes? Headsets, landline phone handsets, car keys and computer keyboards to list but a few. Wireless communication technology has become so robust that most of us take it for granted, so why not let our industrial systems take advantage too? In the seven years since the launch of our Wireless Unit, we’ve had no notable problems reported. It has even been standardised as reliable communication equipment at leading manufacturers in the automotive industry.
Q2. What if my IT department is reluctant to accept the addition of new external wireless networks, thinking that they may conflict with internal network packets?
A2. It’s important to note that our wireless equipment only sends information when necessary, not constantly, in very small network packets. Furthermore, the system incorporates FHSS (Frequency Hopping Spread Spectrum) technology, which has been widely proven for many years to work without problems in areas where several devices transmit information in the same bandwidth simultaneously. All of these factors help to ensure robust and reliable communication.
Q3. Will wireless communication equipment perform stably and reliably in environments where there is a high level of electromagnetic noise, such as spot welding?
A3. The origins of the product’s development are in the automotive sector, whose natural habitat is a sea of electromagnetic noise derived from motors, inverters, heaters, spot-welding equipment, RFIDs and so on. There’s no danger of the equipment being susceptible to failure due to electromagnetic noise. In fact, we know that it’s far more immune to noise than copper communication, almost behaving like fibre optics, but without the associated high costs and delicate care requirements.
