GO1 Robot Interface

Guidelines for interacting with the robot, relevant to GO1’s built-in computers

1. Static Network Connection

For initial setup, use a LAN cable to configure the robot’s WLAN network.

1. On your PC (not the robot), go to Settings → Network in Ubuntu, click on + to create a new connection.

2. Change the connection to Manual in IPv4 settings,

3. set the IP address to 192.168.123.51, Netmask to 24, save, and restart your network.

Once connected successfully, check the host’s local IP by typing in the Host PC’s terminal.

After establishing a successful connection, verify the host’s local IP using the Host PC’s terminal with the command:

ifconfig

Next, ping the robot:

ping 192.168.123.14

Access the robot via SSH:

ssh -X unitree@192.168.123.14

The default password is: 123

Note

At times, the presence of additional networks can create interruptions when connecting to the GO1. It is advisable to have only the connection to the robot active, while deactivating all others.

2. WiFi Connection

Connect to the GO1 WiFi using its hotspot with the default password ‘00000000’.

Access the robot via SSH:

ssh -X pi@192.168.12.1

The default password is:

123

Then you can ssh again into the Nvidia through the pi

ssh -X unitree@192.168.123.14

The default password is:

123

Note

The LAN connection is faster and ideal for development.

3. Screen Connection

Another method for connecting to the robot involves using an HDMI cable along with a mouse and keyboard. This setup enables connecting the robot to your local network, allowing subsequent connections over WiFi.

4. Enabling Internet

To enable internet connectivity on the GO1, ensure it is connected via an LAN cable with internet access, and then simply run:

sudo ip link set eth0 down && sudo ip link set eth0 up
sudo dhclient eth0
sudo apt update

Note

It may take some time for it to get detected, you can check by running ping google.com.

By default, internet is not required

Initialization

1. Powering on the GO1

• Press the battery button once and then press the battery button again, holding it for 3 seconds.

• Press the remote button located on the bottom side of the controller once, and then press it again, holding it for 3 seconds (similar to the battery).

2. Powering the Open Manipulator

Once the GO1 has completed its boot process, proceed to power on the Open Manipulator. This can be done either by connecting the power connector on the top or by activating the power button situated on the U2D2 board within the top housing.

Note

Avoid turning on the Open Manipulator while the GO1 is still in the booting process, as doing so alters its internal mode and may impede communication with the GO1 SDK.

Installation

Please Clone the repository from out github accout to your Ros1 workspace by following the command:

git clone https://github.com/MYBOTSHOP/qre_go1.git

Once the repository is downloaded, navigate to your ROS workspace and install the ROS dependencies.

rosdep install --from-paths src --ignore-src -r -y

Grant permissions and execute to install GO1 Navigation dependencies.

sudo chmod + x go1_install.bash && ./ go1_install.bash

Now build and source your workspace

catkin build -DCMAKE_BUILD_TYPE=Release
source devel /setup.bash

Note

For arm64 (GO1 Nvidia), sometimes the build is not detected so you can replace these lines in CMakeLists.txt in go1 base:

if ("${CMAKE_SYSTEM_PROCESSOR}" MATCHES "x86_64.*")
    set (SYSTEM_ARCHITECTURE amd64)
endif ()
if ("${CMAKE_SYSTEM_PROCESSOR}" MATCHES "aarch64.*")
    set (SYSTEM_ARCHITECTURE arm64)
endif ()

followed by

set (SYSTEM_ARCHITECTURE arm64)

GO1 Operation

If you’ve connected through LAN, you can initiate and operate the robot using

sudo su
source <your_workspace>/devel/setup.bash
roslaunch go1_bringup bringup.launch

1. Teleoperation

rosrun teleop_twist_keyboard teleop_twist_keyboard.py

2. Visualization

roslaunch go1_viz view_robot.launch

Note

This can be run on your own local PC or on the GO1, both should work. Ensure that if you are connecting via WiFi the go1 base launch file has the target ip set to WiFi or else to LAN.

GO1 & Open Manipulator Operation

Note

These are found in the same GO1 repository under the github branch name melodic-robotis.

To launch the GO1 with the Open Manipulator, use the following command:

roslaunch go1_bringup mmp_bringup.launch

For the initial setup of the GO1 with the Open Manipulator, grant permissions to the port using the following command:

sudo chmod a+rw /dev/ttyUSB0

1. GO1 Open Manipulator Namespace

Take note that when using the GO1 MMP (Mobile Manipulation Platform) launch file, all GO1 packages are contained within the namespace “GO1” to avoid conflicts with the open manipulator’s packages. Utilize ROS commands to navigate and understand these namespaces.

rosnode list
rostopic list
rosservice list

By default, the GO1’s normal bring-up does not contain namespaces for every node.

Attention

Ensure to execute this on the GO1 PC with the connected open manipulator! The default PC for this purpose is the Nvidia board with the IP address 192.168.123.14.

2. Open Manipulator Gripper

Open manipulator can be controller via the Moveit arm controller group. The gripper can be controller via the services

To open the gripper

rosservice call /go1_robotis/goal_tool_control "planning_group: ’gripper’
joint_position :
joint_name :
- ’ gripper ’
position :
- 0.01
max_accelerations_scaling _factor:0.0
max_velocity_scaling_factor:0.0
path_time : 0.0 "

To close the gripper

rosservice call /go1_robotis/goal_tool_control "planning_group : ’gripper’
joint_position :
joint_name :
- ’ gripper ’
position :
- -0.01
max_accelerations_scaling _factor:0.0
max_velocity_scaling_factor:0.0
path_time : 0.0 "

For different positions, you may use any value between -0.01 to 0.01, where 0.01 is for opening and -0.01 is for closing.

3. Open Manipulator Demo

The GO1 demo package can be employed to evaluate the Moveit package’s functionality. Initially, make sure the mmp_bringup package is launched:

roslaunch go1_bringup mmp_bringup.launch

Subsequently, execute the GO1 demo package:

rosrun go1_demo demo.py

You can input commands to navigate to pre-defined poses like home, stand, left, right, etc.

4. Open Manipulator Powering Off

When shutting down the open manipulator driver, it is advisable to use the default home pose from Moveit to ensure it rests in a suitable standby position. Failure to do so may result in the Open Manipulator falling.

GO1 & Robosense LIDAR Operation

Note

These are found in the same GO1 repository under the github branch name melodic-robotis-robosense.

To launch the GO1 with the Robosense Lidar, use the following command:

roslaunch go1_lidar lidars.launch

Running this command initiates the lidar driver connected to the robot, and you can observe the point cloud generated by that lidar by executing the visualization command:

roslaunch gi1_viz view_moveit.launch

GO1 Camera

For this, a ROS multi-machine setup is required. Clone this package to the three Nvidia boards on the GO1 with the IP addresses 192.168.123.13, 192.168.123.14, and 192.168.123.15 respectively. When used in conjunction with robot upstart (not covered here yet), it should start up every time the robot boots.

Note

The default camera driver auto-startup on each Nvidia needs to be disabled.

To set up multi-machine functionality, add the client PC details from the code above to the .bashrc file. Replace the IP 192.168.123.— with the Nvidia IP, which can be found using ifconfig (e.g., 13 in this case).

1. Disable Camera Driver startup

Run this on the PC and unlink the camera driver

gnome-session-properties

In some versions

./Unitree/autostart/camerarosnode/cameraRosNode/kill.sh

2. GO1 Navigation

Intended to be run on the host PC.

Odometry Navigation

For navigation based purely on the robot’s odometry, start by running the bring-up:

roslaunch go1_bringup bringup.launch

Next, launch the odometry navigation:

roslaunch go1_navigation odom_navi.launch

3. GO1 Service Examples

This requires the go1 driver to be running, either bringup.launch or mmp_bringup.launch.
