To the relief of those who have invested years in developing software for Pioneer 1, Pioneer 2 truly does combine the best of the new mobile robot technologies with the tried-and-true Pioneer architecture.

Modes of Operation

You may operate your Pioneer 2 or PeopleBot robot in one of four modes:

!Joydrive

!Self-test

!Server

!Standalone

The Pioneer 2/PeopleBot microcontroller comes with 32K flash-programmable, read-only memory (FLASH-ROM) as part of its Siemens 88C166 microprocessor, and an additional 32K of dynamic RAM: 64K total memory space for your standalone robotics programs.

But we don't recommend that you start learning C166 programming. Rather, the robot comes to you installed with the latest P2OS robotics server software.

In conjunction with client software, such as ARIA, or Saphira running on an onboard PC or other user-supplied computer, P2OS lets you take advantage of modern client-server and robot-control technologies to perform advanced robot tasks. (See Chapter 6, Pioneer 2 Operating System, for details.)

Most users run their ActivMedia robot in server mode, because it gives them quick, easy access to its robotics functionality while working with high-level software on a familiar host computer.

For experiments in microcontroller-level operation of your robot’s functions, you may reprogram the onboard flash-ROM and RAM for direct and standalone operation of your ActivMedia robot. We supply the means to download, but not the microcontroller's programming software, for you to work in standalone mode.

In fact, the download utilities we provide for you to reprogram the 88C166-based controller's FLASH and RAM also are used to update and upgrade your P2OS. We typically provide the upgrades free for download from our website, so be sure to sign up for the pioneer-usersemail newslist. That's where we notify our customers of the upgrades, as well as where we provide access to Pioneer and PeopleBot users worldwide.

Finally, we provide onboard software that lets you drive the robot from a tethered joystick. And we provide some self-test programs that exercise your robot’s microcontroller hardware and software. We examine these modes in some detail in Chapter 5, Joydrive and Self-Tests.

2 / PeopleBot specifications

Pioneer 2, also known as PeopleBot, is an advanced mobile robot platform heralded for its versatile design and robust capabilities. Developed by the renowned robotics company Adept Technology, Pioneer 2 has become a staple in the field of mobile robotics, widely utilized for research, education, and practical applications in various industries.

One of the standout features of Pioneer 2 is its exceptional mobility. The robot is equipped with differential steering, allowing it to navigate complex environments with precision. Its compact and sturdy chassis enables it to traverse a variety of terrains, making it suitable for indoor and outdoor exploration. This mobility is further enhanced by an adaptable wheel configuration, allowing for smooth movement even over obstacles.

In terms of technologies, Pioneer 2 is outfitted with an array of sensors that facilitate autonomous navigation and obstacle avoidance. These sensors include laser range finders, infrared sensors, and bumpers, which work in tandem to map the surrounding environment and detect potential hazards. This capability is critical for applications in areas such as warehouse automation or reconnaissance tasks, where safe navigation is paramount.

Pioneer 2 also supports extensive software frameworks, notably the Robot Operating System (ROS). This compatibility allows researchers and developers to leverage a vast library of tools and algorithms, expediting the process of programming and deploying robotic applications. Additionally, the platform can be integrated with various payloads, such as cameras or grippers, expanding its functionality further.

Another significant characteristic of Pioneer 2 is its user-friendly design. The robot comes with an easy-to-use programming interface that empowers users with varying levels of expertise to engage with the technology. Educational institutions often employ Pioneer 2 in robotics courses to provide students with hands-on experience in programming and operating robotic systems.

Powering Pioneer 2 is a rechargeable battery system that ensures extended operation times. This feature is particularly advantageous for fieldwork applications where connectivity to a power source may not be readily available. Importantly, the robot’s modular design facilitates maintenance and upgrades, allowing users to keep their systems current with advances in technology.

Overall, Pioneer 2 (PeopleBot) exemplifies innovation in mobile robotics with its outstanding mobility, advanced sensing technologies, compatibility with leading software frameworks, and a design focused on ease of use and adaptability. It continues to be a preferred choice for researchers, educators, and professionals in the rapidly evolving landscape of robotics.
