Re: Cable Modelling in Vrep

Hi,

For example in loop_1, P_7 is the prismatic_joint2 and Cuboid_13 is the cablepart3 in the shared model.

My question was if gravity is enabled wont the second prismatic joint get activated with the external force since it is free?

Thanks and Regards,
Vignesh

Re: Cable Modelling in Vrep

Hi, Thanks a lot for your reply. I am trying out a planar cable robot. This is what i came up with Base>>revolute_joint1>>rigidbody1>>prismatic_joint2>>rigidbody2>>revolute_joint2>>rigidbody3>>revolute_joint3>>rigid_body4 Basically when I am adding an extra rigid_body I am able to get better results...

Cable Modelling in Vrep

Hi, I am trying to model a cable driven parallel robot. So , Initially I am trying to model a single cable and when I am successful at that I plan to proceed to the actual robot. I have seen some models in the forum to represent ropes which I am able to understand. I know the standard way to model a...

Re: Inverse Kinematics of Parallel cable robot

Hi, Thank you for the response. I made the necessary changes and was able to perform the FK of the model. But for IK I looked at a few examples and completed the model but the tip dummy doesn't follow the target dummy. https://drive.google.com/drive/folders/1pYfjBbl1UjNbWnSiJSM0CEUJImwYneKB?usp=shar...

Inverse Kinematics of Parallel cable robot

Hi, I am working on the IK of a parallel driven cable robot. I was able to do the forward kinematics of the robot. But with the same configuration I am not able do the IK. The joints just breaks and comes apart. I think there is some mistake in the modelling of the joints. Please refer the link belo...

Position vs time input for moving bodies

Hi, I am trying to do a walking simulation. I have the xyz position vs the time (of the COM of foot and pelvis) Is there a way in v-rep to apply the position wrt time to be followed by a particular body? (in the hybrid mode ) For example I have the xyz vs time values of the feet and I want the feet ...

Asti Model ; Forces sensor ; Torques

Hi all, As a part of my Master's Project ; structural analysis of Humanoid robot. I followed a few steps to arrive at the joint loads(Forces and Moments) acting on various links in Asti robot. 1. I scaled the robot by 1.77 times to get the height to 1.8m (similar to average human adult) 2. I entered...

Re: Asti Model info for structural Analysis

Hi,
Thank you for your reply.

I added the lowerlegjoint as a child and the results came out good.
Thanks again
