Comparison between the basic functions of the NAO and those developed by working groups with their relative results.

Group A
Basic function of the NAO	Function developed	Results
• Integrated programming with Python	• Creation of the communication interface between Wolfram Mathematica software and the NAO	• Improved system performance
		• Access to computational processes directly in the Mathematica cloud environment
		• Access to linguistic data resources
		• Image repositories for face and gesture recognition
		• Access to machine learning for emotion recognition
Group B
Basic function of the NAO	Function developed	Results
	• Walking along complex trajectories	New trajectories
• Turn and Walk to a point		• Straight line
• Walking in circles		• Sine
• Finding the way		• Staple
Group C
Basic function of the NAO	Function developed	Results
• Say anything	• Development of complex verbal dialogue	The NAO is able to answer to different questions from those that can be implemented with the basic functions in Choreographe, thus improving the social dialog in the Human-Robot Interaction
• Simple speech recognition
• Distinguishing multiple name
Groups D
