Calculating/Visualizing a Manipulator's Reach Envelope/Workspace

asked 2017-03-20 14:52:47 -0600

I'm interested in developing a custom manipulator, and I wanted to do some iterative studies on link lengths and joint limits by seeing what the resulting reach envelope/workspace is.

Are there any tools in ROS that can help create something like this?

I came across this video of a robot in VREP doing something very similar to what I'm interested in.

OpenRave can do this I believe. Here is an example: http://openrave.org/docs/latest_stabl...

I'm looking into OpenRAVE. It does seem really fantastic, and I actually was able to run a study on my current design, but my issue is...you just get a 3D model with a cloud. How do I compute workspace dimensions and so on with it? There's also no information as to how the color coding is setup?

Great question. Something like that is definitely missing in MoveIt and I don't know of a separate ROS module for that.

I know Shaun Edwards gave a presentation at ROSCon two years ago where he complained about missing tools for this... ( https://vimeo.com/142622435 )

The video you reference looks nice. Do you know whether the code for the visualization is Open Source? The setup in the video is pretty easy and I could imagine things get more complicated when you try to visualize the workspace of a 7-dof arm with rotational joints.

It's not too polished at the moment, but the reuleaux project can do something like that for you.

Yeah, I'm looking into Reuleaux!

Just need to do some stuff to get it to play nicely with Kinetic.
