Nao robot is a bipedal robot with pleasantly rounded features, It can track objects and recognize speech, It can detect falls and triggers protection, It can stand up on its own, It can communicate clearly and effortlessly with students across a variety of cultures, Tactile sensors in NAO’s head, hands, and feet help NAO robot react and respond as needed, NAO robot can hear, see, and recognize you – both who you are, and what you’re feeling. NAO robot is built to move naturally and go just about anywhere, It can detect obstacles, avoid falls, and get right back up again.

NAO6 robot features

Humanoid NAO6 has software Suite Licenses (including Choregraphe, Monitor, and SDK), and 2 years warranty, The programmable humanoid NAO6 robot is available in only one colour: dark grey. NAO robot has custom-designed integrated circuits based on Microchip 16-bit dsPICs microcontrollers, designed to control the actuators, These circuits are responsible for servo-control, bus control, sensor management, and power converters.

NAO6 robot will benefit from Pepper’s autonomous features such as the diagnosis effects, the sleep mode, and other autonomous abilities that make it look alive, The feature “qicli info” helps people who want to test things very quickly on the head of the robot without having to code the application or the script.

NAO6 takes benefit of all the Dialog and QiChat enhancements including a semantic engine (knowledge API + sentence structure) that allows the robot to give clearer and more coherent answers, Interaction with the robot is much improved, and New cameras can improve tracking and people detection performances, The dual stream of the top and bottom cameras is supported.

Programmable humanoid NAO6 specifications

Humanoid NAO6 has dimensions of 574x 311x 275 mm (22.6 x 10.8 x 12.2 inches), It has a weight of 5.48 Kg (12,08 lb), It has Autonomy of 60 minutes in active use at 90 minutes in normal use, Degrees of freedom: 25, Processor: Intel Atom E3845, Compatible OS: Windows, Mac OS, Linux, Embedded: C++, Python, Remote: Java, Vision: 2 OV5640 2592×1944 cameras, Connectivity: Ethernet, Wi-Fi.

Nao robot design

The Nao robot is controlled by a specialized Linux-based operating system, dubbed NAOqi, The OS powers the robot’s multimedia system, which includes four microphones (for voice recognition and sound localization), two speakers (for multilingual text-to-speech synthesis) and two HD cameras (for computer vision, including facial and shape recognition), Nao robot has a software suite that includes a graphical programming tool dubbed Choregraphe.

Actuator unit design

The motors used for the NAO actuators are Maxon coreless brush DC motors, known for precision and reliability, NAO robot has spur and planetary gears in order to have good back drivability, It has special plastics that are loaded with PTFE (Polytetrafluoroethylene) and carbon fiber was used to meet torque and longevity requirements. NAO robot groups two rotary joints together to make a Universal joint module that includes packaging, This allows costs to be reduced and takes into account the mechanical constraints imposed by the outer shell.

NAO robot has 25 degrees of freedom which enables it to move and adapt to its environment, It comes with 7 touch sensors located on the head, hands, and feet, It has sonars and an inertial unit to perceive its environment and locate itself in space, It contains 4 directional microphones and speakers to interact with humans, It comes with Speech recognition and dialogue are available in 20 languages, which are English, French, Spanish, German, Italian, Arabic, Dutch, Portuguese, Czech, Finnish, Russian, Swedish, Turkish.

Computer architecture

NAO’s head has an x86 AMD GEODE 500 MHz CPU motherboard with 256 Mb SDRAM, An additional 1Gb Flash memory is available, Communication with the robot is enabled via the WiFi 802.11g protocol and through Ethernet port, The CPU manages audio, video, and WiFi and other modules, One ARM7-60MHz microcontroller located in the torso distributes information to all the actuator module microcontrollers (Microchip 16 bitdsPICS) through an RS485 bus (throughput of 460 [Kbits/s]).
