Using Nao’s USB Port for Hardware Interfacing

So your Nao robot has a USB port that is, typically, used for reflashing his operating system, but it can be used for so much more. The USB port is located on the back of Nao’s head under a removable cover.

This port is a standard USB and additional devices can be connected to expand Nao’s capabilities. With the release of NaoQi V2.x the underlying operating system has support for the use of 3D sensors, such as the ASUS Xtion, and this can be connected to the USB port.

Additionally, NaoQi is built on a Linux OS which has drivers for the FTDI serial chip range installed as standard. This means that any device that has a serial interface based on the FTDI chipset, to create a serial port, can potentially be used with Nao.

When a FTDI serial device is plugged into Nao, or with NaoQi 2.1.2 when he is booted with it plugged in, a ttyUSB port is created. If you have nothing else connected to the robot the default port assignment will be /dev/ttyUSB0.

UK Nao - NAO Interfaces Hackathon

The UK Nao user group is planning a new hackathon for all hardware and Nao hackers. It's a great opportunity to play with Nao and interface exciting new hardware and systems to him. Queen Mary University London has been kind enough to proivde the space over the weekend of the 11th and 12th of April. With sponsors such as Aldebaran, Thalmic Labs, makers of the Myo gesture armband, Emotion Robotics and more. Want to know what it's all about? Read on......

Nao ASUS Xtion Mount

As many of you are aware, Nao has a big sister called Pepper. Pepper is due for release in Japan this February and, although larger, runs the same operating system as Nao. So what is the difference between Nao and Pepper?

The main difference, on a hardware front, is that Pepper has wheels, laser distance sensors and, most importantly, a 3D camera. The 3D camera provides depth sensing and is based on the ASUS Xtion sensor. This is not the Pro version of the Xtion, just the basic one. Poor old Nao does not have enough room in his head for the Xtion sensor but we can provide access to the hardware via his USB port. So how do we add the sensor to Nao?
