This demo show the communication interface of MR813 motion control board based on Lcm.
|
|||
|
|
Dependency:
|
|||
|
|
- robot_control_cmd_lcmt.py
|
|||
|
|
- robot_control_response_lcmt.py
|
|||
|
|
|
|||
|
|
雷达参数已经能够读取
|
|||
|
|
替换basic_motion_test_comb中的main.py
|
|||
|
|
运行代码之前需要执行:
|
|||
|
|
cd /home/cyberdog_sim
|
|||
|
|
source /opt/ros/galactic/setup.bash
