Re: Custom scatter_shape

CustomUI plugin does not support custom scatter shapes.

You need to modify the plugin to call void QCPScatterStyle::setCustomPath(const QPainterPath &customPath) or void QCPScatterStyle::setPixmap(const QPixmap &pixmap).

Re: Visualize sensor trace

Why do you say it will slow down the simulation? Did you try it?

Drawing object it is only graphical, has no impact on the simulation speed. And since a single object can draw as many items as you want, probably you can solve your problem with just one object.

Re: Visualize sensor trace

You can use sim.addDrawingObject to create a drawing object, which can then moved like any other object.

Use sim.addDrawingObjectItem to add items to the created drawing object.

Re: Motion Planning (OMPL) mobile robot, cannot detect obstacles

I didn't see how you replaced those values. I recommend you having a look at scenes/motionPlanningDemo1.ttt, where collections are used: collisionPairs={sim.getCollectionHandle('manipulator'),sim.getCollectionHandle('environment')} Then use Tools -> Collections to define the two collections.

Re: Motion Planning (OMPL) mobile robot, cannot detect obstacles

Collision pairs passed to simOMPL.setCollisionPairs are supposed to be valid handles returned by sim.getObjectHandle or sim.getCollectionHandle , or sim.handle_all. Why in your code you have: collisionPairs={2000001, -2} ... if collisionPairs ~= nil then simOMPL.setCollisionPairs(t, collisionPairs) ...

Re: Motion Planning (OMPL) mobile robot, cannot detect obstacles

Collision pairs are checked with simCheckCollision. Therefore the objects need to have the collidable flag.

Re: multi-robot exploration

That demo is using MATLAB's Robotics Toolbox to perform mapping. Alternatively, you can find many mapping packages in ROS. I'm not sure wether V-REP's octrees currently allow ray tracing whatsoever. There is also a Octomap plugin that exposes castRay and insertPointCloud functions; however it is not...

Re: How to connect vrep(on windows) to remote ROS master (on ubuntu)?

ROS on Windows is still experimental. I have no experience with that. Try with the tutorial: http://wiki.ros.org/Installation/Windows

Or wait for a ROS 2.0 plugin for V-REP, as ROS2 is supported on both Linux, macOS, and Windows.

Re: XML/text to .ttt(binary files) supported by V-REP

Hi,

V-REP can import SDF files (which are basically XML files conforming to the SDF specification) via the SDF plugin.
