Hi Marc, Thanks a lot! Problem solved! It seems that early version of VREP doesnot work so i switch to the latest version. By the way, could you add on more details on the motion planning documentation in the manual since it is really an important part of my work! Thanks a lot Yours sincerely, Juekun

Hi Marc, Thanks for your reply! I have made the changes you suggested but it doesnot work so i attach the scene file as the link below https://drive.google.com/file/d/0B3-BbMZ2bCmNQ2Z6WGk4elpNcUU/edit?usp=sharing it is actually the same with the file forwardAndInverseKinematics2.ttt, on which i want...

Dear Developers, I am trying to execute motion planning on robot arms but cannot get it work. This https://drive.google.com/file/d/0B3-BbMZ2bCmNMFFycGJ2SmVHeWM/edit?usp=sharing links to the image, which shows the setting i have and the problem i faced, namely, when i compute phase 1 nodes, it warns ...

Dear Developers, I am requesting that more detailed motion planning tutorial be provided, which I consider an essential part of robot simulation. Since i observed that most of your demo scene containing robot with predefined path, it would be better to apply motion planning to solve those problems w...

Hi JK, Doing grasping using mesh collision is always difficult because estimation of penetration and contact generation can be very complex. Use of convex meshes usually leads to better results. For the comparison, ODE is certainly less stable than Bullet for my experience with convex meshes. The n...

Dear friends and developers,

I was wondering which physical engine (Bullet or ODE) is more suitable (in terms of speed, accuracy) for handling collision detection (mesh-mesh collision) for robot arm manipulation tasks?

Thanks a lot in advance!

Hello, In V-REP you can do path/motion planning for: lose objects. We call this path planning . kinematic chains. We call this motion planning . Both planers are based on RRT , or Rapidly exploring Random Trees . In case of the motion planning planer, there is also a stage that calculates several t...

Thanks a lot, my friend!

Dear Developers,

I want to know exactly what algorithms you are using for motion planning or where I can find information about that?
Thanks a lot!

Hi,

I am just wondering if there is a way to change the background color of the script since it is hard to see the yellow statement inside quotation marks "" against the light blue background.
Thanks a lot
