[Unitree] ROS Master not found in Go1 Air

[sktometometo]

I have tried following steps to develop with Go1 Air based on https://github.com/jsk-ros-pkg/jsk_robot/blob/master/jsk_unitree_robot/README.md

1. Connect to the robot via Ethernet

2. Set your PC'S IP address to 192.168.96.162

3. Setup ROS_IP and ROS_MASTER_URI

   rossetmaster 192.168.96.161
   rossetip

I have added step like below, But there seems something wrong.

$ rossetip 192.168.96.162
$ rostopic list
ERROR: Unable to communicate with master!

and ping does not respond.

What is wrong?

Acoording to this document , Laptop Network Configuration should be like

• IP Address: 192.168.123.162/24
• Gateway: 192.168.123.161

And rossetmaster uri should be 192.168.123.161

Is there any robot where internal network is 192.168.96.x?
