Earlier this year the Rover started making deliveries around the city, and after a successful period their responsibilities have been upgraded to hot food.
The robot picks up orders from restaurants and brings them to the customer who then unlocks the robot using their smartphone and lifts out the food.
Three of them are now operating in the White Square area, part of a city-wide fleet of 20 robots.
The Yandex delivery service and its rival, Delivery Club, mean the sight of delivery couriers wearing bright yellow or green overalls with boxy thermal satchels on their backs has become ubiquitous in Moscow in recent years.
Over the summer, five Russian retailers commissioned a monument in Moscow to honour tens of thousands of delivery couriers who it said had kept the capital ticking during a weeks-long lockdown to curb the first wave of the COVID-19 pandemic.
