Meet Pudu Robotics’ BellaBot: a cat like robot that can be used at restaurants to reduce risk of exposure to COVID-19. The robot simply helps with contact-less delivery. It can move and navigate by itself in crowded environments. It has intelligent induction trays and can deliver food to 3/4 tables at a time.
BellaBot has a Cruise mode, so it can move back and forth to deliver snacks. You can find out more about it here.
