All ActivMedia robots operate as the server in a client-server environment: Their

controllers handle the low-level details of mobile robotics, including maintaining the

platform’s drive speed and heading over uneven terrain, acquiring sensor readings, such
as the sonar, and managing attached accessories like the Gripper. To complete the

client-server architecture, ActivMedia robots require a client connection: software

running on a computer connected with the robot’s controller via the HOST serial link and
which provides the high-level, intelligent robot controls, including obstacle avoidance,

path planning, features recognition, localization, gradient navigation, and so on.

An important benefit of ActivMedia Robotics’ client-server architecture is that different
robot servers can be run using the same high-level client. For example, we provide a

robot simulator that runs on the host machine that can look and act just like your real

robot. With the Simulator, you may conveniently perfect your application software and
then run it without modification on any ActivMedia robot. Several clients also may share

responsibility for controlling a single mobile server, which permits experimentation in

distributed communication, planning, and control.

Currently available client software and development environments for the Microsoft

Windows or Red Hat© Linux-based computing platform of your choice include:

ARIA

The ActivMedia Robotics Interface for

Applications (ARIA) is a C++-based
open-source development environ-

ment that provides a robust client-side

interface to a variety of intelligent
robotics systems, including your

ActivMedia robot’s controller and

accessory systems.

Figure 3. ARIA's architecture

ARIA is the ideal platform for integration

of your own robot-control software,

since it neatly handles the lowest-level
details of client-server interactions,

including serial communications,

command and server-information
packet processing, cycle timing, and

multithreading, as well as a variety of

accessory controls, such as for the PTZ
robotic camera, the P2-Gripper,

scanning laser-range finder, motion gyros, among many others.

Some software may come bundled with your robot. Other packages require purchase for licensing. Some

software is also available for alternative operating systems, such as Macintosh, SunOS, Solaris, and BSD Unix.
