Cable Driven Parallel Manipulator

[Anonymous]

Hello Marginally Clever stuff,
I am planing to create a cable driven parallel manipulator, is it more efficient to use extra 4 stepper motors for the cables coming down from the suspended robot to the ground?

I am not sure of what do you mean with “efficiency” in this case. For sure I would not add 4 “bottom” drives just working just in opposition to the “top” drives.

With an opportune choice of the additional axes (in particular, depending on how they are arranged) you will end with additional, non redundant degrees of freedom that you could control.

In other words, if you have 6 or more degrees of freedom, you are potentially able to control both position an orientation (i.e. a Cartesian pose) of the robot in the space.

There are several videos on YouTube showing 6 dof parallel robots using cables.

Perhaps @arditoseku means something like this?

I appreciate your valuable responses. My main point is to obtain 3 degrees of freedom only translation in x,y,z coordinates with Cable Driven Parallel Robot, I was concerned that is it more advantage for me to use more than 4 cables and motors, especially to overcome the slack of cables and vibrations through the working procedure. Is there any idea or knowledge where you can help me with this issue?
Best regards..
