Plenty of businesses are investing in a robots to serve their customers better. That applies to restaurants too. Take the PUDU A1 for instance: it is a smart robot that can identify different types of food and deliver them to each table thanks to deep learning.
The PUDU A1 uses laser & visual SLAM to stop with accuracy of 7mm. It can offset the change in its center of gravity in real-time to ensure high stability. The robot is smart enough to calculate “the space where the dishes are to be placed and correctly places the dishes on the table with optimal obstacle avoidance path planning in real time.”
