Theobjective of this course is to give you the basic tools and knowledge to beable to understand and create any basic ROS related project. You will be ableto move robots, read their sensor data, make the robots perform intelligenttasks, see visual representations of complex data such as Point...
例如:At the core of ROS is an anonymous publish-subscribe middleware system that is built almost entirely from scratch. Starting in 2007, we built our own systems for discovery, message definition, serialization, and transport. The intervening seven years have seen the development, improvement, and...
