Leonidas Assistive Robot

Leonidas is an assistant robot constructed with Lego pieces. Since elderly people respond better to robots than tablets, we have programmed Leo to play interactive games that they would normally play on a tablet. This helps them maintain their cognitive fitness as it tests their memory and reaction times for the games. Leo has the ability to move his arms. As a user, you are expected to press the buttons on the arms indicated by the corresponding LEDs lighting up. Leo has the Amazon Alexa integrated into its system, which allows users to speak to it and choose games verbally. The reason for using both the Alexa and button pressing as an interaction mechanism between the user and Leo is that people benefit from congruent multi-sensory information. Leo also has face detection and table edge detection abilities which make sure it faces the user and doesn’t fall off the table.
