Add diffbot_mbf package using move_base_flex, the improved version of move_base.Test different global and local planners and add documentation.> This is partly implemented (see diffbot_base/scripts/base_controller)Īlso replace Wire.h with the improved i2c_t3 library. Test a low level PID on the Teensy 3.2 mcu using the Arduino library of the Grove i2c motor driver. The current implementation of the ROS Control hardware_interface::RobotHW uses a high level PID controller.Make use of the imu odometry data to improve the encoder odometry using a Kalman filter, such as robot_localization (or the less active robot_pose_ekf).Add diffbot_driver package for ultrasonic ranger, imu and motor driver node code.Use the "2D Nav Goal" tool in RViz (red arrow) to send goals to the robotĬontributions to these tasks are welcome, see also the contribution section below.Localize the robot with the "2D Pose Estimate" tool (green arrow) in RViz.Roslaunch diffbot_navigation diffbot_hw.lauchĪmong other essential navigation and map server nodes, this will also launch an instance of RViz on your work pc where you can use its tools to: Other ROS catkin packages such as rplidar_ros need to be cloned into the catkin workspace.įor an automated and simplified dependency installation process install the vcstool, which is used in the next steps. The required Ubuntu packages are listed in software package sections found in the documentation. The communication between the mobile robot and the work pc is done by configuring the ROS Network, see also the documentation. The packages are written for and tested with ROS 1 Noetic on Ubuntu 20.04 Focal Fossa.įor the real robot Ubuntu Mate 20.04 for arm64 is installed on the Raspberry Pi 4 B with 4GB. diffbot_slam: Simultaneous localization and mapping using different implementations (e.g., gmapping) to create a map of the environment.diffbot_navigation: Navigation based on move_base package launch and configuration files.diffbot_msgs: Message definitions specific to DiffBot, for example the message for encoder data.diffbot_gazebo: Simulation specific launch and configuration files for DiffBot.diffbot_description: URDF description of DiffBot including its sensors.diffbot_control: Configurations for the diff_drive_controller of ROS Control used in Gazebo simulation and the real robot.diffbot_bringup: Launch files to bring up the hardware drivers (camera, lidar, imu, ultrasonic. ![]() The scripts folder of this package contains the low-level base_controller that is running on the Teensy microcontroller. ![]() diffbot_base: ROS Control hardware interface including controller_manager control loop for the real robot.Demonstration SLAM and Navigation Real robot There is also support for different single board computers (Raspberry Pi and Nvidia Jetson Nano) through two changable decks. ![]() It provides mounts for different camera modules, such as Raspi Cam v2, OAK-1, OAK-D and you can even design your own if you like. You can use it directly with the software of this diffbot repository. If you are looking for a 3D printable modular base, see the remo_description repository. The formatted documentation can be found at. This respository contains ROS driver packages, ROS Control Hardware Interface for the real robot and configurations for simulating DiffBot. Its main processing unit is a Raspberry Pi 4 B running Ubuntu Mate 20.04 and the ROS 1 (ROS Noetic) middleware. DiffBot is an autonomous differential drive robot with two wheels. ![]()
