(1) The control of the robot is closely related to the kinematics and dynamics of the mechanism. The state of the robot hand and foot can be described under various coordinates, and the reference coordinate system should be selected according to the specific needs, and the appropriate coordinate transformation should be done. Solutions for forward and inverse kinematics are often required, in addition to the effects of inertial forces, external forces (including gravity) and centripetal forces.
(2) Even a simple robot needs at least 3-5 degrees of freedom, and a more complex robot needs a dozen or even dozens of degrees of freedom. Each degree of freedom typically consists of a servo mechanism, which must be coordinated to form a multivariable control system.
(3) The computer realizes the coordinated control of multiple independent servo systems and makes the robot act according to the will of the person, and even gives the robot a certain "intelligent" task. Therefore, the robot control system must be a computer control system. At the same time, computer software carries a difficult task.
(4) Since the state and motion of the robot are described by a nonlinear mathematical model, with the change of state and the change of external force, its parameters also change, and there is coupling between the variables. Therefore, it is not enough to use a positional closed loop, but also a closed loop of velocity or even acceleration. Methods such as gravity compensation, feed-forward, decoupling, or adaptive control are often used in systems.
(5) Since the actions of the robot can often be completed in different ways and paths, there is an "optimal" problem. For more advanced robots, artificial intelligence methods can be adopted, and computers can be used to establish a huge information base, and control, decision-making, management and operation can be carried out with the help of the information base.
