Re: Line Drawing Object not clearing on simulation stop

You have always the possibility to remote the drawing object in the destruction phase of the child script.

But I still cannot reproduce your problem...

Re: assigning of coordinates

You need to do some work on your own. Have a look at the many examples that come with V-REP (scenes, model, and also python demo scripts in programming/remoteApiBindings/python

Re: Motion Planning Robotic Arm

Hello,

did you check why it gives you an error in routine getConfigConfigDistance?
There is a reason why it gives you an error. Probably one of the variables are nil. You need to find out when the initial error occurs (i.e. when a specific function returns nil instead of something else).

Re: Assing Target and Move Khepera to That Position

Hello, you will have to code an algorithm. The algorithm will: Read the current robot position Compare it to the goal position. If the position difference is small enough, you have reached the goal and should leave the loop Actuate the wheels appropriately, in order to move closer to the goal positi...

Re: Strange behaviour among PCs and in the same PC

Hello,

When you say that the observed velocity is half... does that mean the robot appears to take twice as long to reach a specific location? or does that mean that the displayed simulation time is double, when reaching that same location?

Re: Problem with remoteApi.dll

Hello, during the installation procedure, did you make sure to install the MSVC2015 redistributables? Normally yes, otherwise you should not be able to run version 3.4.0... then the problem is probably something else. Is there any error output from Python when you try to run the program? DO the othe...

Re: Get object matrix from python

Yes, this is actually even better. But you'll have to do the math behind that (i.e. euler angles to rotation matrix, the position coordinates are easy to put into the 4X4 matrix).

Re: Unstable robot at simulation start

Hello,

you seem to have extremely large inertia values for your different robot links. Try reducing them. Then, you will of course also have to adjust the force/torque for each joints, and their target velocity (which is the upper limit velocity your joint can accelerate to).

Re: Extending/ replacing Lua in V-rep

Hello, yes, the fullscreen mode is currently a little bit buggy. In order to use a different lua library than the default library, you will have to do simply replace the lua5.1.dll (or lua51.dll) in the V-REP folder with your new library. This should work if the other lua library has the exact same ...
