Abstract: A robot for making coffee and a method for controlling the same are provided to couple or decouple a portafilter to or from an espresso machine without damage to the espresso machine or the portafilter due to a collision between the espresso machine and the portafilter. The robot includes a robot arm to move with a predetermined degree of freedom, a gripper provided in the robot arm to grip a portafilter, a torque sensor provided in the robot arm to detect repulsive force (Fr) when the portafilter makes contact with a group head of an espresso machine, and a controller configured to set a virtual spring having a predetermined elastic modulus (C) based on the repulsive force (Fr) detected by the torque sensor, and to control driving torque (T) of the robot arm depending on the restoring force (Fe) of the virtual spring.
