Mobile Platform
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

Optimization Of Robotic Parallel Plateform
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.

Re: How To Reduce Degree Of Freedom (Dof)
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. ■
Optimiz The Dof,
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.

Re: How To Reduce Degree Of Freedom (Dof)
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? ■
Freedom's Just Another Word...
The forums are getting quiet. Worthwhile topics are few & far between nowadays & this one certainly doesn't have much value. ■
Optimiz The Dof,
Hi Designer And lzaharis,
Thanks for reply, now i attach the diagram of parallel plateform,in which O point is virtual point it needs to be fixed means its all DOF= 0.
P1,P2 and P3 are rotational joints on X,Y and Z direction i want to fixe Z direction rotation means its DOF = 2
L1,L2 and L3 are linear motor (translation joints) means its DOF = 1
B1,B2 and B3 are same as P1,P2 and P3 so i want its DOF = 2.
can you please tell me how can i calculate these DOF of my parallel platform and how i can write algorithm for this ?
thanks in advance

Re: How To Reduce Degree Of Freedom (Dof)
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.

Optimize Dof
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.

How to Reduce Degree of Freedom (DOF)
HI to all
please can some one give me idea about how to reduse degree of freedom ? i have 6DOF i want to reduce it to 3DOF or 2DOF
i need to find a method how to reduce DOF in mobile platform
Thanks in advance
