Re: drawing rectangle or circle on image obtained from vision sensor
Scene vision/imageProcessingDemo1-lua.ttt does some simple drawing onto the vision sensor image, using the simIM plugin.

Re: using OMPL library for path planning of PKM robot 'irb360'
I'm not sure that I have understood it correctly. Do you mean that there is a chance the IK might not have been calculated during the OMPL compute, and that is why I'm getting a straight line between the initial and target positions? Correct, OMPL doesn't do any IK by default. The default state val...

Re: using OMPL library for path planning of PKM robot 'irb360'
Hi, OMPL has no notion of the robot kinematics, besides knowing a set of joints. For a robot such as IRB360, since it is a parallel kinematics structure, it is first important to understand how its kinematics are implemented (there are two modes: FK and IK, see the robot model for details). Then, re...

Re: Control of the gripper kuka youbot by matlab
Please don't resurrect such old topics. The code referenced in this old topic is not valid anymore, it contains deprecated functions and features, and it does not reflect the current youBot gripper script anymore. Since the behavior of grippers is not standardized yet, and grippers' scripts can chan...

Re: How can I make the Robotiq85 gripper attached to a UR10 robot opening and closing?
From another script, you can call functions
openClicked
and closeClicked
defined in the gripper's script, with:Code: Select all
local gripperHandle = sim.getObject('/ROBOTIQ85')
local gripperFuncs = sim.getScriptFunctions(sim.getScript(sim.scripttype_childscript, gripperHandle))
gripperFuncs:openClicked()

Re: Script Crashing, Trying to rotate robot per orientation
The problem is that you have a situation like: function sysCall_sensing() while ... do ... end end which can't possibly work, because code in sysCalls must not block. Your code doesn't return until a condition becomes true, which would happens several steps in the future, but simulation time can't p...

Re: Looking for example of random pick and place
See also scene ur5WithRg2Grasping which is a simpler example of pick and place.

Re: When the arm grabs the object, it slips away
That can happen when grasping objects in a dynamics simulation. You can increase grasping force or you can increase friction of materials. Or if you don't need dynamic grasping, after a completed grasp, you can rigidly attach the object to the gripper (via a force sensor) before moving the arm. See ...

Hi,
demo scene scenes/pickAndPlaceDemo.ttt does that.

Re: python API function; joint name ambiguity
Remote API: https://manual.coppeliarobotics.com/en/ ... erview.htm
The function to use is sim.getObject (see the example in the above page).
