Robot Evolution Guide

The earliest service robot models feature rather simple, even clunky designs, and relied on marker navigation and manual charging. They often had poor suspension, relatively weak orientation capabilities, and poor reliability when it comes to battery life and other parts. Many of the 1st generation robots are no longer in production or in the process of being phased out. We no longer offer 1st generation robots. 

To qualify for 2nd generation, a robotic model must have an aesthetic industrial design (subjective - yes, so we follow this rule: if most of us think its ugly then it doesn't qualify). It also must have laser navigation, relatively advanced orientation capabilities and good reliability, and at least one of the advanced features: self charging, tray sensors, contactless dispatch/operation, or marketing display.

3rd generation models don't necessarily represent a major jump in the robotic evolution, but in a way represent the "perfect ideal" of what a 2nd generation robot should strive to become. An impeccable industrial design with high quality materials and build, advanced orientation capabilities, laser navigation, self charging  capabilities, tray sensors, contactless dispatch or operation, and high reliability. Marketing features are a plus, but not a necessary qualifier.

4th generation robots fulfill all the necessary criteria of the 3rd generation (except tray sensors), but make the evolutionary jump by being capable of actually serving the dishes on tables.  

What would 5th generation robots look like, and be able to do? Perhaps, they will be able to handle stairs, or steep inclines, without spilling drinks. Maybe they will feature some advanced AI capabilities, or will be able to handle some rudimentary service functions, like pouring water or finding items guests need, like napkins or utensils, and delivering them to the guests. 

One thing is for sure - they are constantly evolving to become smarter and more capable, to become even better hospitality assets.
