Solving a direct kinematics problem for a seven-digit manipulator

The article considers the question related to the solution of the direct kinematics problem for a seven-link manipulator. The author gives a definition of the concept of "manipulator", highlights the main problem of designing robotic manipulators, emphasizes the purpose and features of service robots. The article also gives an example and the results of the solution of the problem under study by using the method of building a kinematic model and coordinate system, proposed by J. Denevit and R. Hartenberg.
