About the Accuracy of Positioning of a Linear Robot Equipped with a High Resolution Optical System
Robots have rapidly become key elements to improve general performances of the existent products, to add up new supplementary characteristics or even in view of creating new products that were impossible to create prior to this research. This paper presents a measuring system with optical device in view of determining velocity variation on the investigated axe of the maximum velocity and acceleration or of their variation in dynamic circumstance. The advanced research of precision parameters is a technical necessity, which leads to the selection of linear actuators according to the conditions of usage. Has been made a measurements stand in order to determine these parameters, a stand equipped with laser ruler with a system of numeric acquisition of experimental data. By analyzing the measuring values presented in this paper it can be concluded that when the positioning precision in the target - point of an acting linear robot or when the trajectory precision is absolutely required, the obtained results must be taken into account. We can operate these appropriate corrections in the system of dynamic programming of the robot.
