Re: VREP definition of friction

For a little more clarity from my side. ODE seems to have to ways to work out friction. We are just wondering which one VRep uses?

Re: VREP definition of friction

Thanks, but there is a distinction on the ODE description, so I am still a bit unclear: ODE's friction models are approximations to the friction cone, for reasons of efficiency. There are currently two approximations to chose from: - The meaning of mu is changed so that it specifies the maximum fric...

Re: Simple Barrett hand

Hi,

Is there any chance you could talk me through separating the two fingers on the other side please?

Thx

VREP definition of friction

Hi, I was wondering if there was a good way to look at how to vary the parameters for materials using ODE: Friction: a friction value. Two colliding objects will have a combined friction value of value1*value2. This does not correspond to the real friction coefficient. Maximum contacts: the maximum ...

Simple Barrett hand

Hi, Currently, the model for the simple Barrett hand closes all fingers at the same time. Is there any way to separate the finger on the one side from the other two? So that the two "sides" can close independently. Making it just a little more realistic. I looked through the tree structure...

Re: Bug fixing in VREP

Thx. Maybe I am just seeing a problem where there isn't one.

Re: Bug fixing in VREP

That sorted a bunch of issues - Yes I knew all the sensors were there, and I was saving them, but not anymore. Doing this uncovered something though. I recorded part of a grasp: https://drive.google.com/open?id=0BzJFg5HZBNCcckpodWNDOENROUk See the red box, its from the moment of inertia which we wor...

Bug fixing in VREP

Hi, I have a scene where I perform a grasp of a mug using the simplified barrett hand. I place the hand, grasp the object and remove the base to see if the grasp is stable using remote API. There are a number of bugs I would like to investigate and correct. I have a 50s video that shows what is goin...

Re: How can I use my own srv in RosInterface

Everything is working and running as expected - thank you again for such an easy to use succinct system. May I ask what these last commands are all about? : cp -r ~/catkin_ws/devel/lib/libv_repExtRosInterface.so ~/Documents/v-repLinuxItems64/variousCompiledItems/ cp -r ~/catkin_ws/devel/lib/libv_rep...
