I have six dof robotic arm from lynxmotion we use our inverse kinematic Equations which are on lynxmotion web page ; but we have some problems I have applied the equations on robot and measured robot position physically by the help of a meter. Results of measurement length and height values are differ from logical length and height values. Physical mesurement is height = 21.5 and width 22. Logical values should be height = 20 and width = 25. This deviation changes when we move the arm dynamically. (increases or decreases on different positions)
Is this type of deviation is normal?. If not what can you advise to us?.
cannot help you any but can you give me the link to the inverse kinetics equations I cannot seem to find them
Thanks
Scott

Thank both of you guys , I think my problem is about Gravity Compensantation do you know anything about that I need G C equations
like inverse kinematic equations do you konw anything about that.I have just writen a program for my ms thesis ;I need a Gravity Compensation mechanism that Rios has if you help me about this subject I would be greateful.
i say tht and friction and null zone ,and u know how servos slow when they near thtere destination there comes a point where there,s not enough power to overcome friction and gravity,mabe a higher min speed,or once it hits min speed speed it back up till it hits the mark ! ?
