Mortar is 130cm tall and weighs 20kg. The battery-operated robot can work for 15 hours constantly, doing most of the jobs of a waiter likebringing drinks to guests and speaking simple words”. The magnetic sensor installed on the floor helps Mortar move throughout thecafé.

The owners of Robo Café are two young men Nguyen Quoc Phi, 30, and Vu Trung Thanh, 25, who had a passion for making robots.

While a student at the Hanoi University of Science and Technology, Thanh successfully made a robot used in the healthcare sector. After graduating, he met Phi who shared the same passion and they learned how to make a waiter robot. It cost them much time and money to finish. After several failures, Mortar was born in late 2017, costing the two young men nearly one year and some 100 million dong (roughly 4,600 US dollars). They were among the first successful manufacturers of robots in Vietnam.

Thanh said Mortar has worked very well since the coffee shop opened. They plan to manufacture three more with smoother movements and better communication to serve in the café. Phi and Trung hope their café will become a familiar rendezvous for young people who love making robots.
