Hi,

The scene given for Blob Detection Pick & Place seems quite complex altogether to understand. Are there any other tutorials or scenes which use Vision sensors for pick and place to get basic working idea???

Thanksss....

Alix, I advise you to restart from scratch with only a conveyor belt and a sensor, because I think a setting has been changed unpurposely. If you have a problem with this basic scene, send it again and I will check out :) I have used "motionPlanningandGraspingDemo.ttt". What I have found ...

Even I have tried commenting all the thread switching code lines in the "Jaco" script,
Later even i tried to remove 'Jaco' script at all.... still, the error is the same.


If Coppelia or anyone else can help, I'll be highly thankfulllll......

But How could i solve it??? I am not getting any idea,

Hi Everyone, My conveyer belt script is not getting the handle of the proximity sensor. Following command is being used : sensor=sim.getObjectHandle('conveyorBelt_sensor') I have rechecked the spellings etc again and again. But still getting this error: Lua runtime error: [string "CHILD SCRIPT ...

Update: I just checked that in the original scene also, if the gripper opening signal is commented, the motion planning fails. Curious what is the problem, I really need a solution for this, waiting for help. Thankssss

Edit: Hi, I am still waiting for help.... Thanks a lot in advancee....

Hi, I am working with 'MotionPlanningwithGraping.ttt'. What I have encountered is that whatever position the target is Jaco is not reaching it with 'closed hand'. But all those targets are reached with 'open hands'. What could be the problem here, I want it to reach the target with 'closed hand', ot...

your robot is simply jumping from one configuration to another, keeping the same end-effector pose. If you want to make that slower, simply put a sim.wait after applyJoints(...). But your robot will still jump from one configuration to another. If you want to have a smoother jump , then you should ...

Hi Everyone, I have followed the "motionPlanningDemo1.ttt' , and designed my scene, i experimented with 1 target at the moment. OMPL calculates the paths for it, and I used the same 'followPath' function to move a robotic arm, but it is moving quite fastly than in the original "motionPlann...
