They create a robot waiter with better abilities than a human being

The artificial intelligence It is advancing by leaps and bounds, so much so that robots are already performing tasks previously only available to humans such as preparing food, cleaning tables, delivering orders and even bringing drinks without spilling a single drop.

Now researchers at the Technical University Munich Institute for Robotics and Machine Intelligence, they have created a model that allows a robot serve tea and coffee faster and safer than a human being.

To do this, they have relied on a robotic arm developed by the manufacturer Franka Emika, they have placed it on a table and connected it to a computer to take advantage of its artificial intelligence.

This robotic arm He is able to pick up a glass filled to the brim, pick it up, rock it back and forth, and not spill a drop.

It is based on the principle of the spherical pendulum

To achieve this milestone, the researchers fed the robot algebraic formulas dating back more than 300 years, in mathematics that is based on the Moroccan tea tray that applies the principle of the spherical pendulum.

“Most approaches have focused primarily on limiting acceleration to keep liquid splash in check. Or they have worked with fluid dynamics to calculate how these substances behave in order to predict the trajectories“, Explain Luis Figueredo, the team’s lead scientist. “That takes at least a few minutes, if not hours, and the outcome is still uncertain.”.

The researchers created this technology for the topic of healthcare and the transportation of hazardous liquids: “But industries involved in transporting materials that present biological and chemical hazards would probably also be interested in a solution like this.”, adds Figueredo.

for now these robots it is working with tactile sensors as a safety mechanism, and yet it retracts instantly when it detects some type of collision, keeping the liquid safe.
