Introduction

Raspberry Pi is a single board computer equipped with an ARM processor developed by the Raspberry Py Foundation in the UK.

Regardless of the embedded board size, Raspberry Pi is very convenient because ordinary Linux (Debian, Fedora, Arch Linux) for ARM and FreeBSD operate and can self-compile on the board as well. Disk is now also inexpensive and can use large capacity SD card, the main unit price is also very inexpensive, around 3000 yen. Also, since basic IO is provided and it can be connected to various external devices, various applications such as robot control and sensor measurement can be considered.

Overview of this Book

Using IO expansion platform PiRT-Unit developed by AIST makes it possible to use IO relatively easily.

PiRT-Unit

Since OpenRTM-aist (C++, Python, Java) can also be compiled and executed on the board, it can be used almost the same as the development process on a regular Linux PC though it is an embedded board.

This section explains the environment building method for developing and executing RT components with OpenRTM-aist, know-how for convenient use, control of mobile robot, usage of IO, etc.
