Re: OMPL collision detection/avoidance vs bounding box

On a side note, is there a way to add a 'safe distance' between manipulator and obstacles? For instance, let the OMPL solution path always be x meters away from the obstacles.

OMPL collision detection/avoidance vs bounding box

Hi Coppelia, I'm trying to use OMPL to generate a collision-free path between configurations. I also use sim.checkCollision() to check if there is any collisions. In this screenshot: https://ibb.co/bH39xV6, I think the arm only collides with the bounding box of the obstacle but not the actual obstac...

Re: motionPlanningDemo1 cannot be ran in v4.2.0

Hello Coppelia, Thank you for the suggestions. I made following changes (code: https://drive.google.com/drive/u/0/folders/1a973NRhBRVCdXaISXrvo00gHCK4xdOkI): - only enabled visible shapes to be collidable - changed all visible shape's self-collision indicators to 0, left others' indictors unfilled -...

Re: motionPlanningDemo1 cannot be ran in v4.2.0

Hello Coppelia, I am trying to move a robot arm between two configurations with an obstacle in between. I tried to follow roadmap_multiquery.ttt and motionPlanningDemo1.ttt , but failed to get the obstacle avoidance working. My code: https://drive.google.com/drive/folders/1a973NRhBRVCdXaISXrvo00gHCK...

Re: motionPlanningDemo1 cannot be ran in v4.2.0

Hi, I added the provided line, but the scene still gets stuck in "info: searching for a maximum of 60 valid goal configurations..."

Do I need to rebuild the scene (like changing API format to the latest) in V4.2.0?

motionPlanningDemo1 cannot be ran in v4.2.0

Hi CoppeliaSim, I would like to achieve the exact same obstacle avoidance as shown in the `motionPlanningDemo1`. When I try to run the example scene `motionPlanningDemo1` from V4.1.0 in V4.2.0, it gets stuck. I am wondering what modifications that need to be done so that it can run in V4.2.0. Thank ...

Re: Display information in scene

I found simTextEditor functions and an example snippet of XML. Is there any way I can append info to the text editor?

I found <text-browser> for simUI.create(). I believe I can update the text by simUI.setText, how should I found the widget ID thou?

Display text information in scene

Hi Coppelia, I'm wondering if CoppeliaSim has a similar function like QTextEdit in PyQt, which can display large trunk of text in real-time? Essentially I would like to display the info from the status bar in the scene (floating window also works). I checked `sim.displayDialog`, but it opens new mes...
