libcreate

C++ library for interfacing with iRobot’s Create 1 and 2 as well as most models of Roomba. create_robot is a ROS wrapper for this library.

• Code API
• Protocol documentation:
  • V_1 (Roomba 400 series )
  • V_2 (Create 1, Roomba 500 series)
  • V_3 (Create 2, Roomba 600-800 series)

Build Status

Dependencies

• Boost System Library
• Boost Thread Library
• [Optional] googletest

Install

    sudo apt-get install build-essential cmake libboost-system-dev libboost-thread-dev

    # Optionally, install gtest for building unit tests
    sudo apt-get install libgtest-dev
    cd /usr/src/gtest
    sudo cmake CMakeLists.txt
    sudo make
    sudo cp *.a /usr/lib

Serial Permissions

User permission is requried to connect to Create over serial. You can add your user to the dialout group to get permission:

    sudo usermod -a -G dialout $USER

Logout and login again for this to take effect.

Build

Note, the examples found in the “examples” directory are built with the library.

cmake

    git clone https://github.com/AutonomyLab/libcreate.git
    cd libcreate
    mkdir build && cd build
    cmake ..
    make -j

catkin

Requires catkin_tools.

    mkdir -p create_ws/src
    cd create_ws
    catkin init
    cd src
    git clone https://github.com/AutonomyLab/libcreate.git
    catkin build

Running Tests

To run unit tests, execute the following in the build directory:

    make test

Known Issues

• Clock and Schedule buttons are not functional. This is a known bug related to the firmware.
• Inaccurate odometry angle for Create 1 (#22)
• Some 600 series models incorrectly report the OI Mode in their sensor stream (create_robot #64)
  • To enable or disable the OI Mode reporting workaround, pass true or false to setModeReportWorkaround()

• Contributors: Daniel Smith, Jacob Perron, Josh Gadeken, Stefan Krupop, tim-fan

2.0.0 (2019-09-02)

• Cleanup examples
• Use std::chrono instead of custom timestamp function
• Remove Trusty CI job
  • Since it is EOL.
• Default to C++11
• Add compiler flags '-Wall -Wextra -Wpedantic'
  • Fix warnings as a result.
• Disconnect from serial cleanly on SIGINT
  • Send the STOP opcode before exiting the program to ensure the robot is not left in a state that could potentially drain the battery.
• Initialize variable for compiler compatibility
• Add other serial communication options Otherwise, it's possible that Operation "7" (0x07) is confused for "135" (0x87)
• Add cliff sensor example
• Add API for getting left and right cliff detections
• Update wheeldrop example
• Add API for getting left and right wheeldrop
• Use shared pointer when binding callback for serial read (#38)
  • Resolves an issue with ROS Melodic on 18.04.
• Fix for compatibility with Boost 1.66
  • Compatibility with at least as early as Boost 1.58 still persists
• Update wheel diameter for Create 2
  • Now matches the spec from iRobot.
• Add Bionic CI job
• Add static cast to fix compiler warnings
• Use package.xml format 3
  • Make catkin dependency conditional on ROS 1.
• Add Xenial build to CI
• Remove std::cout statement
• Contributors: Anton Gerasimov, Jacob Perron, Ryota Suzuki, Yutaka Kondo

1.6.1 (2018-04-21)

• Build and install gtest as part of CI
• Update README with instructions for building and running unit tests
• Remove external cmake project for gtest Now only build tests if a gtest installation already exists on the system. This should expedite time to build for users that do not care about building/running unit tests and also eliminates the need for internet access when building.
• Add test depend to gtest in package.xml
• Contributors: Jacob Perron

1.6.0 (2018-04-07)

• Add unit tests (gtests)

• Refactor Packet API

  • Declare setData member as protected
  • Rename 'setTempData' to 'setDataToValidate'

• Remove redundant packets from Data constructor

• Updated setDigits function API comments

  • added HTML to adjust for spacing in diagram, showing the
