1. composition of control system and moving parts-the accuracy and sensitivity of various control elements are different, and it is also related to the presence or absence of azimuth response equipment. The moving parts include the parts of the secondary manipulator itself and the parts of the grasped object.
2. Accuracy stiffness-When the structural stiffness and contact stiffness of the auxiliary manipulator are low, the positioning accuracy is generally low, because it is easy to oscillate.
3. Positioning methods-Different positioning methods have different influencing factors. For example, when positioning a mechanical stop, the positioning accuracy is related to the stiffness of the stop and the speed when contacting the stop.
4. Positioning speed-The positioning speed of the auxiliary manipulator has a great influence on the positioning accuracy. This is because the energy consumed by moving parts is different when the positioning speed is different. Generally speaking, in order to reduce the positioning error, the positioning speed should be controlled reasonably, such as improving the buffering function and capacity of buffering equipment, and controlling the driving system to slow down the moving parts.
5. The pressure fluctuation of hydraulic and pneumatic driving sources, as well as the fluctuation of voltage, oil temperature and air temperature will affect the repetitive positioning accuracy of the secondary manipulator. Therefore, choose the necessary methods to stabilize the pressure and adjust the oil temperature. If the accumulator is used to stabilize the oil pressure, the heater or cooler is used to control the oil temperature, and the temperature and pressure are used to compensate the flow control valve at low speed.
