Would you be so kind as to explain in greater detail what you are asking us? I do not understand your question.

assuming it is mechanical:

Per wiikipedia-

In three dimensions the six degrees of freedom of a rigid body are sometimes described using these nautical names

Tilting side to side - rolling

Moving left and right- yawing

Tilting forwarfd and back - pitching

Moving up and down - heaving

Swaying - moving left and right

Moving forward and backward - surging

hi dears,

Can you help me about to reduce the DOF ( Degree Of Freedom) . I have 6 DOF of Robotic parallel plateform. I want to optimize it and make 3 DOF or 2 DOF. so please some one help me about its key ponit of my project . please gauid me about to reducing the DOF. i ll be thank full.

Thanks In advance.

I have a vague idea, but the questioner has given so little detail I really can't be bothered until we get a much more definitive question. ■

Hi Dear , Gesigner And lzaharis,

Which kind of detail and question due you want to ask? tell me about i ll try to give you more and more detail about . actually i just want starting ponit from where i can make the strat my project i want to reduce the DOF of my parallel plateform, which current have 6 DOF i want to make calculation and algorithem about it .

Please help me

Thanks for reply me.

If I remember correctly the 6 degrees of freedom would be -

Translation in X axis

Translation in Y axis

Translation in Z axis

Rotation about X axis

Rotation about Y axis

Rotation about Z axis

So which of these degrees of freedom do you need to keep, and which do you need to fix? ■

The forums are getting quiet. Worthwhile topics are few & far between nowadays & this one certainly doesn't have much value. ■

I believe you need an arrangement of six hydraulic cylinders or linear actuators joining the two platforms as indicated in the attached sketch.

That's as far as I can help you. You know, these forums are for matters related to BULK MATERIALS HANDLING, and as far as I can see this question has precious little to do with bulk materials handling.

Hi Designer ,

Thanks if you find some thing else so please send it to me , my e-mail id is syedrizwanulhaq@hotmail.com, and i have to use that plateform which i attached .

thanks once again.
