Robotics as a Useful Tool to Improve the Hydration of the Elderly

The aim of this clinical trial is to evaluate the effectiveness of a hydration educational program executed through a robot in comparison with the usual hydration program in terms of fluid intake and general health status of the residents. The main question to be answered is whether the use of robotics through a humanoid robot increases the hydration of institutionalized older people. Participants: * The intervention group will receive a hydration plan executed by the robot and the control group will receive the center\'s usual hydration plan. * Healthcare personnel will receive reminders from the robot to record fluid intake through it. In the control group, health personnel will perform the fluid intake record in paper format and at the end of the shift, as usual.
