geometry_msgs/Twist消息用于描述一个刚体(例如机器人)的线速度和角速度,而geometry_msgs/TwistStamped则通过添加一个时间戳字段,使得该消息能够包含时间信息,这在处理时间序列数据或进行时间同步时非常有用。 注意,标准的ROS消息类型使用斜杠(/)而不是双冒号(::)来分隔包名和消息名,因此正确的类型名称是geometry_...

获取当前速度 话题名为/current_velocity,消息类型为Geometry::TwistStamped,主要信息为三轴线速度与三轴角速度。 由于autoware车辆为阿克曼转向方式,虽然在速度参数定义时包含了三轴速度与角速度,但实际上只使用了x轴的线速度(车辆前进速度)和z轴的角速度(车辆水平转向),随后会加以分析。 设置预瞄距离,并选取next_po...
