Amazon has many massage tables at reasonable prices such as https://www.amazon.co.uk/gp/product/B076HJ8Q8H/

This model allows you to add some connectors for the modular mounting system so that you can attach motors, cameras, servos, or whatever else you want to thehead end of your table.

Why would you want to do this? If you need to ask, you probably don't want to know... ;)
