Abstract:
A mechanism-parametric-calibration method for a robotic arm system is provided, including: controlling the robotic arm to perform a plurality of actions so that one end of the robotic arm moves toward corresponding predictive positioning-points; determining a predictive relative-displacement between each two of the predictive positioning-points; after each of the actions is performed, sensing three-dimensional positioning information of the end of the robotic arm; determining, according to the three-dimensional positioning information, a measured relative-displacement moved by the end of the robotic-arm when each two of the actions are performed; deriving an equation corresponding to the robotic arm from the predictive relative-displacements and the measured relative-displacements; and utilizing a feasible algorithm to find the solution of the equation. When an ambient temperature changes or a stress variation on the robotic arm exceeds a predetermined range, re-obtaining the set of mechanism parametric deviations corresponds to a current robot configuration.

Claim (Index 15):
The mechanism-parametric-calibration method as claimed in  claim 13 , further comprising:\n when a first-direction pitch between an out-of-range first-direction predictive positioning-point and the first precision plane exceeds the maximum sensing distance of the measuring instalment in the first direction, controlling the robotic arm so that the end of the robotic arm moves toward the out-of-range first-direction predictive positioning-point which is in front of a second precision plane of the calibration block to sense the first-direction measured displacement between the end of the robotic arm and the second precision plane, wherein the second precision plane is perpendicular to the first direction; when a second-direction pitch between an out-of-range second-direction predictive positioning-point and the third precision plane exceeds the maximum sensing distance of the measuring instrument in the second direction, controlling the robotic arm so that the end of the robotic arm moves toward the out-of-range second-direction predictive positioning-point which is in front of a fourth precision plane of the calibration block to sense the second-direction measured displacement between the end of the robotic arm and the fourth precision plane, wherein the fourth precision plane is perpendicular to the second direction; determining the first-direction measured relative-displacements according to a first-direction displacement parameter and the first-direction measured displacements; and determining the second-direction measured relative-displacements according to a second-direction displacement parameter and the second-direction measured displacements, wherein the first precision plane and the second precision plane are the first-direction displacement parameter apart; and wherein the third precision plane and the fourth precision plane are the second-direction displacement parameter apart.
