(Tutorial introductionWith the landing of robot products, many robot enterprises have a huge demand for talents in the direction of motion planning. Many undergraduate and graduate students in Colleges and universities are eager to learn the cutting-edge principles of robotics and practical engineering.In the process of developing this course, we believe that as a robot course, it should have strong practicability. We hope you can directly use it in the actual robot after learning the course. In view of this, the practice or engineering realization of the course will account for a large proportion.)
