In the study of Nonlinear problems establish back analysis method, people gradually find and establish a material parameters method that make the corresponding displacement value and the measured displacement value with the least error .Obviously, for the practical engineering design and construction the most reliable results is the one that on the whole make the most close to the result between based on the obtained results calculated displacement and the measured displacement.
(3) Therefore, when the number of the total Measurement information is more than the total number of unknown variables to be calculated , That is when ,we can define the objective function is as: (4) In order to let the Square sum of error between the objective function like Eq.3 or the best estimate is become least, need to meet the conditions for: (5) Take Eq.4 into Eq.5 , after Expansion ,we can get Eq.6 or Eq.7: (6) (7) Write into matrix form: (8) It is Canonical equation Optimization processed through the principle of least square method, from Eq.8 we get Eq. 9: (9) Obviously, formula (9) is the General Expression of Linear algebraic equations that we can use to solve the material

Robots working in a cooperative manner can also be used in material handling, e.g., transporting objects beyond the load carrying capacity of a single robot.
This method is much cheaper than using force sensors, is reliable and solves some problems which appear to decentralized force control (here the object can be made of any material rigid or not, the grippers can be vacuum grippers, etc.) all that because the force sensing is not needed anymore.
