Synopsis:

The subject undrestands the robot as a dynamical system. Its design, identification, control and programming will be introduced. The methods can be used for other electromechanic systems, e.g., production machines and manipulation devices.

Requirements:

The knowledge of basic methods of dynamic modeling of mechanical systems. The knowledge of the basic method of kinematical analysis of spatial mechanisms and especially robots (inverse kinematical problem, direct kinematical problem). The knowledge of basic methods of the control of systems.

Syllabus of lectures:

1. Basic methods of dynamical modeling - Newton-Euler equations.

2. Basic methods of dynamical modeling - principle of virtual work, Lagrange equations.

3. Special methods for dynamics in robotics - inverse dynamics problem, composite rigid body method, recursive methods.

4. Modeling of robot dynamics with flexible bodies - eigenfrequencies, eigenmodes, flexible multibody modeling.

5. Planning of robot motion, analysis of dynamic capabilities of robot on the trajectories.

6. Synthesis of kinematic and dynamic properties and structure of robots.

Study Objective:

The main goals of the study of subject are the student skills in the field of the dynamic analysis of robots, their design, identification and control. The knowledge from the control system theory will be applied to robot control problems. The knowledge from the identification, synthesis and calibration will be extended and applied to robotics.
