This release is running ROS 2 Galactic with the following interface library versions:

Release Overview

As with the last release, this one provides the robot's sensors and controls via topics, actions, and services.
iRobot® Education Bluetooth protocol functionality has been greatly improved in this release; we have released the iRobot Education Python Web Playground to interact with the robot.
Please be sure your robot's BLE/USB Toggle is in the "BLE" position in order to use the robot in this mode.
Note that when the Bluetooth1 radio is enabled, the USB-C2 port cannot communicate with a downstream device (though it remains powered).

Known issues

Core Robot

  • Robot may require multiple connection attempts when changing Wi-Fi networks
  • Robot will restart application when its connectivity changes, including connection changes with Wi-Fi or the USB interface, or when it receives a new DHCP lease. This is helpful for autoconfiguration with DDSes but can be disruptive.
  • Robot prefers time sync from Wi-Fi over its USB interface

ROS 2

  • When using CycloneDDS, invoking ROS 23 actions causes a memory leak on the robot. When the robot runs out of memory, it will automatically restart the application. Follow this issue for more information.

iRobot® Education Bluetooth protocol mode

  • Robot does not recognize disconnection for thirty seconds.
  • Changing Bluetooth name in the webserver does not modify advertisement name until application is restarted
