This repository contains ROS support packages for the Ranger robot bases to provide a ROS interface to the robot.

• Ranger Mini V1.0

• Ranger Mini V2.0

• Ranger

1. Install dependencies

$ sudo apt install libasio-dev libboost-all-dev

2. Clone and build the packages in a catkin workspace

$ cd ~/catkin_ws/src
$ git clone https://github.com/agilexrobotics/ugv_sdk.git
$ git clone https://github.com/agilexrobotics/ranger_ros.git
$ cd ..
$ catkin_make

3. Setup CAN-To-USB adapter

• Enable gs_usb kernel module(If you have already added this module, you do not need to add it)

  $ sudo modprobe gs_usb
  

• first time use scout-ros package

  $ rosrun ranger_bringup setup_can2usb.bash
  

• if not the first time use scout-ros package(Run this command every time you turn off the power)

  $ rosrun ranger_bringup bringup_can2usb.bash
  

• Testing command

  # receiving data from can0
  $ candump can0
  

4. Launch ROS nodes

• Start the base node for ranger

  $ roslaunch ranger_bringup ranger.launch #for ranger

• Start the base node for ranger_mini_v1

  $ roslaunch ranger_bringup ranger_mini_v1.launch #for ranger_mini 1.0

• Start the base node for ranger_mini_v2

  $ roslaunch ranger_bringup ranger_mini_v2.launch #for ranger_mini 2.0
