Equally, will you want the same software for each one?
Think as well about whether and how you could use a robot outside exhibitions. (Could it be used in the office, perhaps in your reception area, for example?)
Consider the technical support you are likely to require. If you hire a robot, you are likely to have more technical help on hand, rather than having to deal with any issues yourself.
You may well find that robot hire is a very cost-effective option, especially if you don’t attend numerous trade events throughout the year. At the same time, hiring gives you the flexibility to wipe clean the content on the robot, or reuse the information for the next show.
So give some thought now to how a robot could set your organisation apart next time you attend a trade show or similar event. Attract people to your stand with one – and get them talking about and remembering your brand.
