Chapter 2 What Is Pioneer?

Pioneer is a family of mobile robots, both two-wheel and four-wheel drive, including the Pioneer 2-DX, -DXe, -CE, and -AT, and the PeopleBot (V1 and Performance) Mobile Robots. All are intelligent mobile robots, whose client-server architecture was originally developed by Kurt Konolige, Ph.D., of SRI International, Inc. and Stanford University.

ActivMedia’s robots are truly intelligent, off- the-shelf mobile platforms, containing all of the basic components for sensing and navigation in a real-world environment, including battery power, drive motors and wheels, position-speed encoders, integ-

Your ActivMedia robot also has a variety of expansion power and I/O ports for attachment and close integration of additional sensors and other accessories. Expansion includes an addressable I/O bus for up to 16 devices, two RS-232 serial ports, eight digital I/O ports, five A/D ports, PSU controllers and more—all accessible through a common application interface to the robot server software, P2OS.

With the onboard computer option, your ActivMedia robot becomes an autonomous agent. With Ethernet-ready onboard autonomy, your robot even becomes an agent for multi-intelligence work.
